"The environmental quality is not the best, only better." At the recent meeting of environmental continuous improvement held by Jigang, the relevant leaders of the enterprise emphasized that Jigang is building a "city steel mill" that is harmonious and friendly with the city. The National Games will be a test for enterprises and a new starting point for environmental protection in Jigang.
On February 26th last year, 12, Wang Jun, Chairman of the 16th Workers' Congress of Jigang Group, made a long speech on environmental issues in his work report. Facing more than 2,000 workers' representatives, he solemnly said: "Holding the National Games in Jinan next year will not only bring us pressure, but also bring us an opportunity to show our corporate image. The whole company should consciously establish the concept of ecological civilization and environmental responsibility, turn pressure into motivation, accelerate the construction of' urban steel mills' and create a green and harmonious National Games. "
This kind of pressure is invisible and huge. Although it was awarded the honorary titles of "National Environmental Friendly Enterprise", "National Greening Model Unit" and "China Iron and Steel Industry Cleaner Production and Environmental Friendly Enterprise" last year, the decision-makers of Jigang did not feel any satisfaction and relaxation in environmental protection work. The factory of Jigang is less than 10 km away from the venues and airports of the National Games, and it is surrounded by traffic arteries. A cloud of black smoke and sewage will discredit the National Games and the image of Shandong Province and Jinan City. "The National Games is at home. What should we do? " In 2009, Jigang faced up to the gap, raised the standards, studied and formulated the environmental protection targets of that year, and signed the responsibility letter of the total emission reduction targets of major pollutants with the municipal government in March. The first goal stipulated in the responsibility book is to ensure the normal operation of the first sintering machine. 1, sintering machineNo.: Flue gas desulfurization facilities of sintering machine of Casting Pipe Company 120m2, reducing SO2 emission1000t; The second is to ensure that the comprehensive sewage treatment plant can meet the discharge standards stably, and the COD can be reduced by 300 tons.
With the help of the National Games, Jigang's environmental protection work is moving towards a higher level.
"Environmental Responsibility" in Crisis
The countdown to the National Games is one year, which is the period when the global financial crisis is the most rampant and the production and operation of Jigang encounter great difficulties and challenges. "Dealing with the crisis, reducing costs and improving efficiency must not be at the expense of the environment. The more difficult it is, the more we must adhere to scientific development and harmonious development. " Based on the investment of 654.38+0.5 billion yuan in 2008 and the implementation of 29 environmental continuous improvement projects, Jigang redefined 20 environmental improvement projects in 2009. According to Ye Bing, head of the Environmental Protection Department of the Ministry of Safety and Environmental Protection, in the case of extremely tight funds, Jigang actively applied for special funds for environmental protection from provincial and municipal environmental protection departments, on the other hand, it gave priority to ensuring funds for environmental remediation projects and promoted the continuous emission reduction of pollutants, which fully reflected the high sense of social responsibility of a large state-owned enterprise. The desulfurization and dust removal project of sintering machine of cast pipe company, which invested 8.3 million yuan, took the lead in adopting "double alkali method" for desulfurization in China, which has the characteristics of fast reaction speed, high efficiency and low operating cost.
After the project is put into use, the dust emission concentration of sintering machine head is greatly reduced, and the SO2 emission concentration is less than 200mg. SO2 1540 tons was reduced in the first half of the year, exceeding the annual emission reduction target. The dust removal projects of No.2 Ironmaking Plant 1 1- 12 and 13 were successfully completed and put into use this year1October 20th, completely eliminating the two major pollution sources. The dust removal reconstruction project of coking coal charging car with an investment of 42 1 0,000 yuan has been put into trial operation, and the steel slag wet grinding magnetic separation project of coal charging company with an investment of 654,380+0,659 yuan is being put into trial operation. It is estimated that the coking ammonia evaporation wastewater treatment project with an investment of more than 50 million yuan is undergoing preliminary preparation and scheme demonstration.
Developing circular economy is an important way to promote energy conservation, emission reduction and environmental friendliness. Since the beginning of this year, Jigang has continuously improved the development level of circular economy with the goal of building a "city steel mill". They strengthened the effective recovery and utilization of natural gas and optimized the structure of on-grid power generation. In the first half of the year, they used waste heat to generate 654.38+0.4 billion kWh of electricity, up 5.5% year-on-year, and the self-sufficiency rate of production electricity was close to 60%. According to estimates, this alone is equivalent to saving 600,000 tons of social coal resources and reducing CO2 and SO2 emissions by 6.5438+0.6 million tons. Establish the concept of "saving water is protecting the environment", give full play to the role of Donglian water supply project and comprehensive sewage treatment plant, and realize zero extraction of deep well water and resource utilization of mine water. In the first half of the year, the consumption of fresh water per ton of steel decreased to 3 cubic meters, down by 0. 1 1 cubic meter year-on-year, saving 550,000 cubic meters of fresh water, and reducing the COD emission of the comprehensive sewage treatment plant by 290 tons, which is close to the annual target issued by the municipal government.
All employees "protect the environment"
For the sake of the National Games, for the sake of future generations, it has become the unshirkable responsibility of Jigang workers to keep the blue sky and white clouds and protect the clear water.
It is fundamental to maintain good environmental quality and stable operation of environmental protection facilities. Li Yuxin, director of the environmental monitoring station of the Ministry of Safety and Environmental Protection, said that the environmental protection department of Jigang has established a system of scientific statistics, strict monitoring and strict assessment, and implemented a daily and monthly declaration system for key pollution reduction facilities, especially the comprehensive sewage treatment plant, the flue gas desulfurization facility at the head of the 1 sintering machine, and the sintering machine of the casting company, and approved the reduction of pollutants once a month to implement process performance evaluation. In the main smoke (dust) emission sources, an online automatic smoke monitoring device is added, which is networked with the provincial environmental protection bureau to strengthen the whole process monitoring. In accordance with the new emission standards, strict supervision is focused on the dust at the sintering machine head to ensure that the emission reaches the standard. They monitor smoke emission and smoke control, and give timely feedback when they find smoke; For wastewater discharge and wastewater treatment facilities, analyze the causes in time and follow up the rectification. In the first half of the year, 8 rectification notices were issued and 23 issues of environmental quality weekly were issued. In order to suppress dust, Jigang also purchased more than 6,543,800 square meters of tarpaulin, covering the open-air storage yard comprehensively, sprinkling water regularly to suppress dust, and ensuring air quality.
At the end of last year, the dust emission value of the 320m2 sintering machine chimney in the Second Ironmaking Plant was as high as 150mg/m3, exceeding the standard emission value of 70mg/m3. "If you can't solve this problem, you can only stop." Wan Jicheng, director of the sintering center of the factory, said. Through refined management, finding the "blind spot" and optimizing the process, the dust removal equipment was technically reformed. Since the beginning of this year, the dust collector at the sintering machine head has been running stably, the synchronous operation rate has reached 100%, the flue gas emission standard has always been kept below 60mg/m3, and the dust recovery has increased by 15 tons every day. Based on the profit of 300 yuan per ton of dust removal ash, the economic benefit in the second quarter alone reached 405,000 yuan, changing the "subtraction" of environmental protection into the "addition" of benefits. The implementation of environmental protection measures has won the respect of Jigang in the market. In 2008, Jigang was ranked 1 1 in the 2008 "China's Most Respected Listed Company Award" jointly organized by the global authoritative financial magazines Buffett Magazine, World Economist Weekly and the global authoritative enterprise competitiveness research institution-World Enterprise Competitiveness Laboratory. At the same time, Jigang actively declared the sixth "China 25 Most Respected Listed Companies Award" in 2009.
The environmental monitoring station of Anhuan Department of the National "Demonstration Post for Female Workers" is a female soldier composed of 14 female workers, and is mainly responsible for monitoring the external drainage, air, wastewater discharge, environmental noise and environmental factors in the workplace. In order to grasp the environmental information, the causes of pollutants and the environmental quality in time, the female staff of the monitoring station carried out the three-dimensional operation of "water, land and air" in Shili Steel City, and distributed high-temperature and toxic gases in the long and narrow underground corridors, belt ditches, kiln chimneys and dust removal facilities at an altitude of tens of meters, beside the sewage ditches bitten by mosquitoes in summer and frozen in winter. They said: "As long as our production and living environment is getting better and better, it's nothing if we are dirty and bitter." In the first half of this year alone, they completed more than 20,000 environmental monitoring and analysis data and compiled more than 100 monitoring reports, which provided an important basis for environmental improvement and pollution reduction in Jigang.
