Analysis of Xi’an’s Urban Domestic Waste Disposal Policy Source: New West Update Time: 3-26 14:28 During the Western Development Period, Xi’an is accelerating urban development With the continuous increase of urban population and the steady improvement of the living standards of urban residents, the amount of urban domestic waste generated in Xi'an will inevitably increase. Therefore, actively treating urban domestic waste as resources and carrying out comprehensive utilization will not only help solve the ecological and environmental problems caused by urban domestic waste, but also provide certain resources for urban development, which is of far-reaching significance. 1. The current situation of urban domestic waste treatment in Xi'an City. At present, the domestic waste generated in Xi'an urban area is about 3,500 tons every day, and about 1.8 million tons are generated annually. 90% can be recycled. About 200 tons of plastic are recycled every day. Among them, 60% is about fruit peels and vegetable waste, 30% is waste paper and plastic, about 4% is glass, and the rest is metal, cloth, etc. Xi'an currently generally uses three methods for domestic waste disposal: sanitary landfill composting and incineration for power generation. Xi'an has now built 1 landfill gas power plant, 1 comprehensive treatment plant (composting and incineration) and 2 hazardous waste centralized disposal plants. Most of the garbage in the urban area is transported to the Jiangcungou harmless landfill for sanitary landfill. Jiangcungou Landfill is the largest domestic waste landfill in Xi'an. It is located in Baqiao District, about 18 kilometers away from the city center, and has a garbage storage capacity of 49.5 million cubic meters. The entire project is planned to be divided into two phases. The first phase covers an area of ??240 acres and has a garbage storage capacity of 2.82 million cubic meters. It was put into operation in June 1994. The second phase of the project is planned to cover a total area of ??1,100 acres and has a garbage storage capacity of 49 million cubic meters. It is understood that the plan also proposes that Xi'an will build 11 new garbage treatment plants. Six of them will be built in the near future: a domestic waste incineration power plant will be built west of Liucunbao with a daily processing capacity of 1,000 tons of domestic waste. It will be responsible for processing all domestic waste in Lianhu District, part of Weiyang District and Jiyang Group. Expand the domestic waste incineration thermal power plant based on the "Medical Waste Disposal Center" in the Jinghe Industrial Park in the northern suburbs, with a daily processing capacity of 600 tons of domestic waste. It is responsible for processing all domestic waste in Jingwei District, Economic and Technological Development Zone and Xinzhu District, and part of Weiyang District . A domestic waste incineration thermal power plant will be built to the north of Chang'an Industrial Park in the southern suburbs, with a daily domestic waste processing capacity of 1,000 tons. It will be responsible for processing domestic waste in Chang'an Industrial Park, Chang'an University Town, all of Chang'an City, Beilin District, and the southern part of Yanta District. The Lintong domestic waste sanitary landfill will be constructed near Daiwang Village in the east of Lintong District with a daily landfill capacity of 500 tons to dispose of urban domestic waste in Lintong District. The Yanliang domestic waste sanitary landfill will be constructed near Podi Village in the northern part of Yanliang District, with a daily landfill capacity of 200 tons, to dispose of urban domestic waste in Yanliang District. A Hu County domestic waste sanitary landfill will be constructed near Cuicun in the eastern part of Hu County, with a daily landfill capacity of 400 tons, to dispose of Hu County's urban domestic waste. "Xi'an Urban Domestic Waste Incineration Power Generation Project" is located in Dizhai Town, Baqiao District, Xi'an City. It has a planned area of ??120 acres and a total investment of 760 million yuan. It operates in the BOT mode and is designed to incinerate 1,800 tons of waste per day. The installed capacity is 48MW and it is mainly responsible for processing domestic waste in the main urban areas of Xi'an. The project is expected to start before the end of 2008 and be completed and put into operation before the end of 2009. In addition, construction waste that cannot be recycled will be disposed of in landfill. , it is planned to set up 3 to 4 construction waste landfills in the east, west, south and north directions of the main urban area, and to set up 3 to 4 construction waste landfills around the towns in Lintong, Yanliang and Hu counties. After the completion of these 11 garbage treatment plants and municipal solid waste incineration power generation, they will greatly alleviate the demand for municipal solid waste treatment in Xi'an and at the same time provide a portion of electric energy or heat energy for local economic development and residents' lives. In summary, they are prioritized for development. Recycling, moderate development of incineration power generation and composting are the best ways to treat urban domestic waste as resources in line with the actual development of Xi'an. 2. Thoughts on the treatment of urban domestic waste in Xi'an 1. Strengthen waste management through legislation. On the other hand, foreign governments attach great importance to legislation.
For example, the German government invites public representatives to hold symposiums to discuss, let the public participate in environmental protection legislation, formulate more specific laws and regulations, and strengthen waste management through public participation in legislation. In the 1990s, Xi'an City promulgated laws and regulations for garbage disposal such as the "Urban City Appearance and Environmental Sanitation Management Regulations" and the "Urban Domestic Waste Management Measures". However, due to the lack of corresponding implementation details and poor operability, many practices The practices deviate from these laws and regulations, and the enforcement is not strong, which brings great difficulties to legal management. The Shaanxi Provincial Government must pay attention to the legislative behavior of urban waste management and learn from good foreign practices, as shown in Table 1. According to the development and changes of urban domestic waste, various laws and regulations are constantly improved, and waste management methods in line with my country's national conditions are formulated. Measures taken by foreign countries to manage garbage through legislation Table 12. Improve the collection and management of garbage disposal fees Many foreign countries have adopted the collection of garbage disposal fees to strengthen garbage disposal. For example: All costs for municipal waste disposal in Finland come from the garbage disposal fees paid by residents, and the cost is determined based on the capacity of the trash bin and the number of dumping times. In Japan, you have to pay for oversized garbage disposal rolls for oversized garbage, and you have to pay recycling fees and collection and transportation fees for discarded household appliances (air conditioners/TVs/refrigerators/washing machines). In 1998, the Shaanxi Provincial Government formulated the "Interim Measures for the Collection and Management of Bagged Urban Domestic Garbage in Xi'an" requiring citizens to implement bagging of garbage. In 2005, the Xi'an Municipal Price Bureau issued the "Implementation Opinions on Charging for Municipal Domestic Waste Disposal in Xi'an". However, looking at the overall situation, the urban garbage disposal charging mechanism in Xi'an is not yet perfect. For example, the collection area is too small, and many districts, counties, communities, streets, etc. have not yet levied domestic waste disposal fees; the charging standards of each unit and department are different, and there are major problems. gaps; inconsistent charging methods, etc. Therefore, in order to solve the problem of garbage disposal fee collection, it is necessary to formulate management methods for garbage disposal fees, unify charging standards, and at the same time increase management efforts in accordance with relevant laws and regulations. 3. Strengthen garbage classification and recycling. Xi'an still mainly collects garbage in a mixed manner. Domestic garbage has not been collected, transported, and processed in a classified manner. Many recyclable and renewable garbage have not been recycled, and some of them are hazardous waste. It has not been detoxified or specially recycled. For example: garbage is simply divided into recyclable garbage and non-recyclable garbage, and the classification is not detailed enough. In order to facilitate garbage recycling, a trash can should be divided into several compartments or several independent classified trash cans should be established to clarify the categories. Japan divides domestic waste into 12 categories, including: flammable materials, bulky materials, cans, bottles, soft drink bottles, plastic containers, dry batteries, small metals, aerosols, paper, cloth, and non-woven fabrics. Burning things. The purpose is to provide convenience for garbage collection personnel to transport garbage to garbage treatment plants for classification, processing and recycling. The United States implements classified collection of household waste. The classified resource waste is placed at the door and is collected by garbage trucks for free. The money obtained from selling the resource waste is evenly distributed to each household according to the amount of resource waste collected in each district to pay for the next purchase. Monthly garbage disposal fee; you can also send the valuable parts to 27 recycling centers in the city by yourself. The deposit will be refunded for items subject to the deposit system. Items without deposit can also be sold. Judging from the waste disposal methods in the above developed countries, Xi'an's waste classification and recycling is far behind that of some foreign countries. Due to comprehensive reasons such as insufficient government investment, insufficient publicity, people's insufficient understanding of the benefits of garbage classification, and backward equipment of the environmental protection department, Xi'an still has a lot of work to do in garbage classification and recycling. 4. Strengthen publicity and education on garbage classification and recycling. We should publicize the importance of garbage classification and recycling through extensive publicity, education and advocacy work on garbage classification, and call on every citizen to actively participate in garbage classification and recycling. 3. Gradually improve the legal system for urban domestic waste treatment in Xi'an. Compared with foreign countries, the current legal system for urban domestic waste treatment in Xi'an is not perfect and its operability is poor. Therefore, we must first establish and improve the legal and regulatory system for urban domestic waste in legislation as soon as possible, and further improve the management mechanism, thereby providing legal protection for the industrialization and socialization system of Xi'an's domestic waste.
First, strictly implement the new "Measures for the Management of Urban Domestic Waste" promulgated by the Ministry of Construction in April 2007, and formulate the "Xi'an Municipal Domestic Waste Classified Collection and Classified Recycling Management Regulations" as soon as possible to establish the classified collection and classified recycling of municipal domestic waste in legal form system to ensure the smooth progress of classified collection, classified recycling, classified transportation, and classified processing; second, the "Regulations on Supervision and Punishment of Municipal Domestic Waste Pollution Prevention and Control" should be formulated as soon as possible to implement a license and qualification review system for enterprises participating in the treatment and disposal of urban domestic waste , and monitor domestic waste treatment and disposal facilities as sources of pollution, and punish units or individuals that cause environmental pollution due to improper treatment and disposal; third, the "Xi'an Municipal Waste Material Recycling Comprehensive Utilization Management Measures" is formulated as soon as possible, and the supporting "Waste Electronic Products Recycling "Management Measures", "Waste Tire Recycling Management Measures", etc., clarify the responsibilities of production enterprises in recycling and mandatory recovery rates, use the law to ensure the establishment of a waste material recycling system, and effectively promote the recycling and reuse of waste materials; 4. It is necessary to formulate the "Xi'an Municipal Domestic Waste Treatment Industrialization Regulations" to provide basis and guarantee for accelerating the industrialization of domestic waste treatment. For example, it is necessary to clearly stipulate the price of municipal solid waste incineration power generation, landfill gas power generation price, municipal solid waste processing subsidies, etc. etc., to ensure the enthusiasm of enterprises for comprehensive utilization of resources; fifthly, the "Xi'an Municipal Domestic Waste Disposal Special Plan" is formulated every five years, taking the urban domestic waste problem in Xi'an as a key research topic, and providing Xi'an domestic waste treatment in stages. Solutions and References. The disposal and management of urban domestic waste is a complex system. To achieve the goal of "reduction, resource utilization, and harmlessness" of waste, it is necessary to pass legislation and strengthen publicity and education to make every citizen aware of the importance of waste classification and collection. Benefits, consciously become a member of protecting the environment and beautifying the city, thereby achieving sustainable development of the city. References [ 1 ] Li Keguo.

It is one of the core enterprises of Mingride Group and is mainly engaged in: environmental protection engineering design, construction, and domestic waste disposal. On November 4, 2005, Mr. Fulgen was invited to attend the Wuxi-Chengdu economic symposium co-organized by the Sichuan Provincial Government and the Wuxi Municipal Government. His company's famous brand project "WST" water-based series products received great recognition at the symposium. Highly praised. The "WST" water-type series products are considered to be the most advanced, most environmentally friendly, and most comprehensive recycling treatment technology in the field of urban domestic waste treatment technology in the world. Currently, they have been used in Shuozhou City, Hubei Ezhou City, Jiangsu Province Muyang County, Wuxi City and other places have built several municipal solid waste treatment production lines with a daily processing capacity of 500 tons. After more than a year of operation, local governments have expressed great satisfaction. The technology has been proven in practice through the display of complete sets of system equipment. feasibility and superiority.
This technology is all developed by our company. The core device has obtained a number of invention patents from the United States, China, Taiwan and other countries and regions. In 2003, it obtained the PCT world priority, and has successively applied for patents including the European Union and the Asia-Pacific region. A total of more than 100 world invention patents. We believe that with the systematic promotion and application of WST, a new way will be created for the proper disposal of large amounts of urban domestic waste, and it will have an important radiating effect on the construction of the social environment, urban economy, culture and health, etc., in the near future In the future, we will definitely create a beautiful home for mankind with green mountains, green hands, fertile soil and blue sky. WST is a professional enterprise that mainly provides environmental protection engineering design and domestic waste treatment solutions, including the design, construction, installation, commissioning and operation of waste sorting and treatment systems and other supporting equipment, providing one-stop services. We *** spent 5 years understanding and researching the rules related to domestic waste and breaking the rules to carry out research and development. After 7 years of hard work, we finally changed the old treatment concept of "big and big" to the concept of "small and small". Domestic waste currently has quite mature processing technology and equipment and achievements, and has been put into official operation on the market. WST triggers the concept of "small" The concept of "small" in WST means that when processing a large amount of domestic waste, small areas, small equipment, small capital, small energy consumption, and small manpower can be used to achieve large areas and large equipment. , a treatment technology that requires a lot of energy and a lot of manpower, and is faster, hygienic, dust-free, and odorless than large-scale treatment methods. In addition, it can achieve full sealing, full automation, and full resource recovery. The concept, and the various new integrability theories generated therein, will write a new page in the field of domestic waste treatment. WST's innovative concepts and technologies have obtained multiple national invention patents and world patent priority. The first set of processing equipment with a daily capacity of 500 tons of municipal solid waste established in Wuxi, China, has passed the registration enterprise standards of China's National High-tech Demonstration and Quality and Technical Supervision Bureau, passed the inspection by the Product Quality Supervision and Inspection Institute, and entered the production stage. The WST technology platform consists of the following technologies: . WST fully automatic water classification waste treatment system can not only separate dry and wet materials to more than 95%, but also subdivide various types of materials with different properties into ten categories. . CMP Rapid Refined Compost Technology The organic matter after WST water separation is used to make 100% fertilizer using a special CMP rapid fertilizer production system. The fertilizer production process is fast and uses bacterial strains for high-temperature fermentation. It can kill diseases, pests and bacteria in the material. Pure natural organic fertilizer. ． Recycled plastic pellet technology uses classified waste plastics to process them into secondary recycled plastics, which can reduce plastics from being burned or buried and comprehensively solve the problem of white pollution. . RDF Derived Fuel Manufacturing Technology: After classification, non-recyclable debris is processed by WST to form RDF derived fuel. The electricity recovered is more than 50% higher than that of direct incineration of waste to generate electricity; it can also avoid landfills and help increase the life of landfills.
