Since last year, Guiyang has launched the largest and most comprehensive air pollution control work in history. It has established a leading group for improving environmental air quality in Guiyang and launched a joint effort by 28 member units. Seven special treatment tasks were carried out: road dust control on construction sites, motor vehicle exhaust pollution control, industrial waste gas control, dietary fume control, oil and gas recovery control, non-coal mine control and environmental greening improvement.
According to analysis, the reason why dust pollution has become one of the main reasons affecting the ambient air quality in Guiyang is because with the rapid development of urbanization and industrialization in Guiyang, multiple construction sites have started working at the same time, causing dust The pollution sources are widely distributed and are unorganized emission sources. Some construction sites are not constructed according to regulations.
To curb dust pollution, blocking the source is the key. Since 2013, regarding the current dust pollution status of construction sites and roads in Guiyang City, the housing construction, urban management, traffic management and other departments have jointly enforced the law, increased inspections of construction sites, and strengthened daily supervision of engineering transport vehicles and waste trucks.
According to statistics, last year the municipal and district housing and construction bureaus inspected 1,276 projects under construction and issued 1,156 rectification notices. For the 24 construction sites with many problems during inspections and supervision, the 33 construction units and 19 supervision units involved were notified and criticized in batches, and the construction units and supervision units were suspended from participating in project bidding activities and undertaking new construction projects. project until the rectification review meets the requirements, and bad behavior records of the construction unit and supervision unit will be recorded and included in the integrity and credit files.
At the same time, the Guiyang Municipal Public Security and Traffic Management Bureau investigates and punishes various traffic violations that affect air quality, especially construction transport vehicles (including slag trucks) that are prone to generating dust, and *** plans to investigate and deal with projects There were 3,245 traffic violations committed by transport vehicles; the Municipal Urban Management Bureau dispatched more than 9,860 sanitation vehicles and more than 58,000 sanitation workers to manually clean and clean sanitation facilities (pepper bins, trash cans, garbage collection boxes, etc.) every day. The average daily manual cleaning area is 17.23 million square meters, and the mechanical washing area is 9.4 million square meters; in 2013, the city's environmental inspection agency inspected 300,689 motor vehicles, and the environmental protection regular inspection rate was 95.63. The city's *** issued (including replacement) There are 290,000 sets of motor vehicle environmental protection signs. The verification and issuance of motor vehicle environmental protection inspection qualification marks has laid the foundation for Guiyang City to carry out separate management of motor vehicles.
Starting in March this year, Guiyang City has launched a new round of joint inspections of ambient air quality, intensifying efforts to control dust pollution at construction sites. Through open inspections and secret inspections and joint inspections at night, the focus is on Inspect issues such as nighttime construction sites, road dust and slag transportation, and dust pollution from non-coal mines.
During this period, the Guiyang Municipal Housing and Urban-Rural Development Bureau strictly implemented grid management of 665 construction sites, assigned the supervision responsibilities of civilized construction to each specific supervisor, and supervised the entry of vehicles on the construction site. Cleaning and prevention of spillage, coverage of debris and materials, implementation of dust reduction measures, hardening and cleaning of entrances and exits, etc.
At the same time, the Guiyang Municipal Housing and Urban-Rural Development Bureau also cooperated with the Municipal Urban Management Bureau and the Municipal Public Security and Traffic Management Bureau to conduct nightly joint checkpoints, setting up checkpoints on key road sections in Guiyang every night to check passing garbage. Earth-moving trucks, commercial concrete trucks and sand and gravel transport trucks, etc.
Multi-pronged approach -
Initial results appear
In addition to dust control, Guiyang City has also launched a "combination punch", starting from six We have taken a multi-pronged approach to air pollution prevention and control and achieved phased results.
Motor vehicle exhaust pollution has become an important source of air pollution. In order to reduce the negative impact of excessive motor vehicle exhaust on air quality, the Guiyang Motor Vehicle Pollution Prevention and Control Center carried out regular environmental testing of motor vehicles, standardized motor vehicle maintenance services, and random inspections of motor vehicles and exhaust-polluted roads. In 2013 , the city's environmental inspection agencies inspected 300,689 motor vehicles, with a regular environmental inspection rate of 95.63. 275 motor vehicles were randomly tested throughout the year, effectively eliminating vehicles with unqualified exhaust emissions from driving on the road.
Gradually promote industrial waste gas treatment.
In recent years, in order to achieve energy conservation, consumption reduction and pollution reduction, Guiyang City has adjusted the city's industrial layout, completed the relocation of Guiyang Cigarette Factory and Guizhou Cement Factory, and promoted the relocation of Guizhou Tire Co., Ltd. and Shougang Guiyang Special Steel Plant; gradually A number of corporate waste gas treatment projects have been completed, including the flue gas desulfurization of coal-fired boilers of Chinalco Guizhou Branch to produce sulfuric acid, the yellow phosphorus tail gas power generation of Guizhou Qianneng Tianhe Phosphorus Industry Company, and the comprehensive utilization of yellow phosphorus tail gas of Qingli Tianmeng Chemical Company to produce sodium formate. The "Comprehensive Plan for the Prevention and Control of Industrial Air Pollution in Guiyang" was formulated, and 67 industrial enterprises were designated as key prevention and control enterprises, with designated personnel responsible for prevention and control, and a comprehensive inspection of the operation of the company's environmental protection facilities, smoke and dust pollution, and exhaust gas emissions up to standard. Implement relocation and renovation of high-energy-consuming and high-pollution enterprises in the central city. Three of them: Guiyang Weishuanyuan Food Co., Ltd., Guiyang Kangle Bean Industry Co., Ltd., and Guiyang Sanlian Dairy Co., Ltd. plan to move out of the central city within the year. Guizhou Laogandie Food Co., Ltd. has included the change of coal-fired boilers to gas-fired boilers in its work plan. Completed the denitrification project renovation of five cement production lines of Guiyang Conch Panjiang Cement Co., Ltd., Guizhou Jinjiu Cement Co., Ltd., Guiyang Orchid Cement Co., Ltd., Guizhou Miaoling Building Materials Co., Ltd., and Kaiyang Zijiang Cement Co., Ltd., and is expected to reduce nitrogen oxides annually. The emission volume is more than 1,400 tons.
Comprehensive launch of the food fume control project. At present, Guiyang City has completed a thorough investigation of catering units within 1 km of the ten key areas. Among them, 150 catering units have installed oil fume purification devices, and the remaining 32 will fully complete the oil fume purification devices before June 30, 2014.
