Chongqing's goal is to build on the continuous improvement of the quality of the environment. According to the results approved by the Ministry of Environmental Protection, last year, the city's sulfur dioxide emissions amounted to 746,100 tons, which was 36,300 tons less than the previous year's, which was a decrease of 4.64%, exceeding the national task of reducing emissions by 4.5%; chemical aerobics The amount of emissions was 239,800 tons, which was a decrease of 0.81% over the previous year's emission reduction of 0.19 million tons. It also exceeded the 0.7% reduction target set by the state.
Chongqing's “double excess†fulfilled its emission reduction targets, mainly due to the city’s efforts to optimize its industrial and product structure, actively changing its development mode, and focusing on improving the quality of the city. The city has strictly controlled the projects with backward technology, high energy consumption, serious pollution, and low added value in new industrial projects, and has controlled new increments of pollution. At the same time, the use of various means to explore the overall mode of emission reduction, such as the strict implementation of desulfurization preferential electricity price and other pollution emission reduction economic policies, actively explore the experimental emissions trading rights, vigorously implement the environmental relocation project, the full implementation of "green credit" work , increase the total amount of emission reduction funds and so on.
The chemical industry is a pillar industry in Chongqing, especially the new construction of the Changshou Chemical Industrial Park. Chongqing’s chemical industry has become increasingly prominent. In response to the development of resources and environmental pressure brought about by the chemical industry, the Chongqing Municipal Government has formulated opinions on the structural adjustment of the chemical industry, and relocated or shut down and transfer chemical companies with high energy consumption, heavy pollution and poor technology, and a large number of chemicals and The environmental relocation of key polluting enterprises has played a very important role in achieving success in energy conservation and emission reduction in Chongqing. In this context, the importance attached to energy conservation, emission reduction and environmental protection work by chemical companies in Chongqing continues to increase. For example, Chongqing Changshou Chemical Co., Ltd. has implemented a neutrophil latex degassing project and a rubber tail gas incineration remediation project in response to issues such as rubber tail gas, wet acetylene odor, boiler and calcium carbide furnace fumes that have long affected the surrounding environment. Through the combination of source control and end treatment, the rubber tail gas pollution problem was solved. The dry acetylene project was implemented, and the dry acetylene new process was used instead of the wet acetylene process, which effectively solved the problem of the wet acetylene carbide slurry volatilizing exhaust gas. In addition, the company also strengthened energy management and vigorously implemented energy-saving technological transformation work, and implemented 56 energy-saving emission reduction and recycling economic projects. In 2008, the company completed the “Eleventh Five-Year†energy saving task ahead of schedule. In 2009, the comprehensive energy consumption per million output value decreased by 4.3% from the previous year.
Chongqing Changfeng Chemical Co., Ltd.'s new aniline project has achieved stable and complete production of the equipment in 2009. Natural gas consumption has dropped from 500 cubic meters per ton of product to 300 cubic meters. In December 2009, in the case of a natural gas supply of only 20,000 cubic meters per day, the company maintained a high aniline load level through the application of N-methylaniline by-produced hydrogen, accumulating 29,478,000 tons of coal throughout the year. Tons of standard coal. In addition, Chongqing Minfeng Chemical Co., Ltd. has undergone environmental relocation and has continuously adopted new equipment and new processes to accelerate the development of comprehensive utilization of resources. From 2003 to 2009, the company accumulated a total of 680,000 tons of chromium slag. At the same time, it used dry detoxification of waste chromium residue from old factories. By the end of 2009, it had disposed of nearly 80,000 tons of waste chromium residue. The company has also undergone a technical transformation and reused the previously directly discharged standard waste water for production, reducing the production water from 130 to 150 tons per day to about 20 tons, saving nearly 90% of water.
Huang Qifan, mayor of Chongqing pointed out that environmental protection work should focus on optimizing energy structure, promoting industrial upgrading, developing low-carbon economy, promoting green consumption, strengthening ecological environmental protection, and improving the target responsibility system. To ensure the completion of energy-saving emission reduction tasks, it is imperative to speed up the completion of environmental relocation tasks. All responsible units must ensure energy-saving and emission-reducing investments, and ensure that the planned emission reduction projects are completed and benefit from the prescribed time, especially chemical companies.
This year, Chongqing’s COD emission reduction target was set at 0.5%, and sulfur dioxide emission reduction was achieved at 1.5%. It is intended to complete the “Eleventh Five-Year†total emission reduction task in the first half of the year. In terms of pollution prevention and control, the city's industrial enterprises will achieve 98% compliance with pollutant discharge this year. The city's urban sewage treatment rate will reach 80%, and urban trash disposal rate will reach 90%. Chongqing has taken great strides in further improving the quality of the environment, optimizing development methods, and improving the quality of the city.
Chongqing: Chemical Reform Promotes Urban Quality Improvement
The three times of the 3rd plenary session of the Chongqing Municipal Commission for the 3rd session recently proposed that Chongqing’s urban environmental goals should be upgraded to a higher level this year: the air quality in the main city will meet more than 300 days, and at the same time the establishment of a national environmental protection model city will be started. To further improve the quality of the environment, optimize the development methods, and enhance the quality of the city.
