Summary of environmental protection work of private aluminum smelting enterprises
I. Company Profile The company was established on September 28th, xx. It is a private enterprise specializing in aluminum smelting and has 750 employees. The 230ka large-scale pre-baked aluminum electrolysis project is one of the key construction projects of the province. The design work of the xx branch of the xx aluminum-magnesium design institute is designed to design an annual production capacity of 140,000 tons of aluminum ingots. After the project is put into production, the annual sales income can reach 2 billion yuan. 250 million yuan, the project has a total investment of 850 million yuan. It is built in two phases. The existing scale is the first phase of 70,000 tons. It was successfully put into operation in two batches on February 28 and July 8 of xx, with a total of 108 tanks. The total investment is 450 million yuan, the annual electricity consumption is 1 billion kwh, and it is put into operation to the end of xx. The total output of aluminum ingots is 937,57.637 tons. In the first quarter of this year, the total output of aluminum ingots was 15,876.362 tons.
Second, the process characteristics of the company sy230 prebaked anode electrolyzer, which integrates various advanced technologies and achievements at home and abroad, using a fully enclosed automated material handling system, high-energy efficiency automatic monitoring flue gas purification and recovery system, using intelligent fuzzy control The system, the whole process assists in the management of aluminum electrolysis production, as well as the smooth supply and delivery system with higher degree of electrical automation and the advanced spectral analysis quality monitoring facilities. The process is compact and the degree of automation is high. It is in the forefront of the same industry in the country. Process, belonging to the clean production process of the electrolytic aluminum industry.
III. About environmental protection For the electrolytic aluminum industry, environmental protection is a very important basic condition. Since xx years, the state has introduced many measures to implement environmental protection policies, and closed many environmentally unsatisfactory enterprises. Therefore, it was established in this environment. The importance of xx aluminum industry to environmental protection work is self-evident. The company's leaders conscientiously implement the relevant national industry policies and systems, and look at the problems from a long-term perspective, whether in the construction period or the current production period. Do not forget to do a good job in environmental protection, to achieve a high starting point, high requirements, specifically to do the following:
1. High standard design, laying the foundation of technology The impact of electrolytic aluminum production on the environment is air-based. Fluoride is the main characteristic pollutant of emissions. In addition, it is dust. In order to achieve the standard construction, our company first proposed to the design unit. According to the requirements of the national policy to achieve production standards, after the re-screening, the national-level design unit-xx aluminum-magnesium design institute xx branch was selected, and the group selected more than 20 large and medium-sized aluminum plants nationwide. Finally selected the sy230 series slot;
2. Highlighting the governance, focusing on the implementation of the technical compliance company, it is very concerned about environmental compliance, strictly in accordance with the "Environmental Air Quality Standards", "Urban Regional Environmental Noise Standards", "Industrial Enterprise Boundary Noise Standards", "Surface Water" The national standards such as Environmental Quality Standards, Comprehensive Emission Standards for Air Pollutants and Boiler Air Pollutant Emission Standards are supervised and perfected, and the external supervision and internal management are truly implemented, and the electrolytic flue gas recovery and purification system installed by the company is fully utilized. Potential, classified management, strict compliance:
First, increase investment to ensure that environmentally-friendly hardware meets the standards. The company has a total investment of 450 million yuan in the first phase of 70,000 tons, and a total investment of about 50 million yuan in environmental protection. It has two sets of purification and recovery systems, a fully enclosed material supply system, and the use of bag filter and wenqiu. The principle of recycling and purifying in the dry process, centralized treatment of all flue gases in the electrolyzer, and discharge to the standard;
Second, the classification is up to standard and comprehensive management. The pollution of electrolytic aluminum is nothing more than gas, dust, fluorine and slag. For the above-mentioned pollution sources, the company has classified and dismantled gas, solid and slag through technical treatment. The effective substances are retained and utilized, the harmless gas is discharged to the standard, and the solid materials are used repeatedly or as raw materials of other industries. Not only the treatment but also comprehensive utilization, turning waste into treasure, creating benefits for the enterprise and reducing losses;
Once again, ensure that environmental protection facilities are 100% operational. Recognizing the importance of environmental protection, we also tasted that the comprehensive management is the sweetness of turning waste into treasure. All the company's environmental protection equipment ensures 100% operation in 24 hours, laying a scientific foundation for creating a beautiful and clean environment. At the same time, the company has set up a purification and recycling workshop, and also established the Anhua Branch to ensure that the company's environmental protection atmosphere is managed, supervised, executed, and long-term benign operation. In addition, the company also actively invited the county and city environmental protection departments to guide and strengthen monitoring, timely rectification and improvement, and ultimately meet industry standards.
3. Greening the enterprise environment and optimizing management indicators In order to further strengthen the workers' environmental awareness, the company organized employees to carry out voluntary greening activities. The company spent more than 500,000 yuan on the 90% of the first phase of the plant. Greening, and the division of responsibility areas, into the company's door to give people the feeling of a real garden-style factory, the company is thriving, all indicators have entered the advanced level of the industry:
1. The quality of aluminum ingots for hj brand remelting meets the national standards and declares provincial famous products;
2. The AC power consumption of the original aluminum is below 14000kwh/t-al and reaches the domestic advanced level;
3. Fluoride emission concentration is 1.9mg/nm3, dust emission concentration is 8mg/nm3, dust removal efficiency is over 99%, and these indicators have achieved leading level in the same industry;
4, the implementation of fully enclosed loop water, basically no industrial water discharge;
5. The enterprise and the surrounding areas have truly achieved mutual supervision, jointly managed and shared environmental advantages.
4. Long-term unremitting efforts to create tomorrow's environmental protection enterprises With the development of enterprises and the progress of society, environmental protection compliance has become a consensus and requirements. Our company has also planned future environmental development plans. We will summarize past achievements and learn. External success experience, constantly improve the company's environmental image, actively respond to the national policy, cooperate with the environmental protection departments at all levels to increase efforts, seek truth from facts, do a good job in the economic development of enterprises, do a good job in environmental protection, and make unremitting efforts to create tomorrow's environmental protection. enterprise.
