Ministry of Ecology and Environment: The second national pollution source survey mainly achieved five results.
CCTV News:The State Council Press Office held a press conference at 10 am on June 10th. Zhao Yingmin, Vice Minister of the Ministry of Ecology and Environment, and the responsible persons of the Bureau of Statistics and the Ministry of Agriculture and Rural Affairs introduced the bulletin of the Second National Pollution Source Survey and answered questions from reporters.
In response to a reporter’s question, Zhao Yingmin, Vice Minister of the Ministry of Ecology and Environment, pointed out that the results of the second national pollution source survey are mainly reflected in five aspects:
First, the basic situation, quantity, structure and distribution of all kinds of pollution sources in China have been found out.By the end of 2017, the number of various pollution sources in China was 3,583,200 (excluding mobile sources), including 2,477,400 industrial sources, 639,500 domestic sources, 378,800 livestock and poultry farms and 84,000 centralized pollution control facilities. Among them, the number of various pollution sources in Guangdong, Zhejiang, Jiangsu, Shandong and Hebei provinces accounts for 52.94% of the national total, and the number of pollution sources in China, especially the number of industrial pollution sources, basically shows a gradual decrease from east to west. In terms of industries, five industries, namely, metal products, non-metallic mineral products, general equipment manufacturing, rubber and plastic products, and textiles and garments, account for 44.14% of the total industrial pollution sources in China. In addition, by the end of 2017, there were 267 million motor vehicles, 4.132 million construction machinery, 762 million kilowatts of diesel power for agricultural machinery and 278,000 ships in operation. In 2017, the fuel consumption of national railway diesel locomotives was 2,461,800 tons, and civil aviation took off and landed 10,248,900 times. The above is the basic distribution of all kinds of pollution sources.
Second, we have mastered the emissions of various pollution sources.From the national water pollutant discharge situation, the chemical oxygen demand is 21.4398 million tons, the total nitrogen is 3.0414 million tons, and the ammonia nitrogen is 963.4 million tons. In terms of emissions, the Yangtze River, Pearl River and Huaihe River basins have large drainage areas and involve many provinces, and the emissions of pollutants such as chemical oxygen demand, total nitrogen and ammonia nitrogen are relatively large. From the perspective of emission intensity, the pollutant emission intensity of unit water resources in Haihe River, Liaohe River and Huaihe River basins is large. The national air pollutant emissions are: 17,852,200 tons of nitrogen oxides, 16,840,500 tons of particulate matter and 6,963,200 tons of sulfur dioxide. This time, we also investigated the emissions of volatile organic compounds in some industries and some fields, with a national total of 10.1745 million tons. Beijing-Tianjin-Hebei and its surrounding areas, the Yangtze River Delta and the Fenwei Plain are areas where the emission intensity of air pollution sources per unit area is relatively high in China. As we all know, these three areas are also key areas for air pollution prevention and control determined by the state. The situation of solid waste in China is as follows: in 2017, the output of general industrial solid waste was 3.868 billion tons, the comprehensive utilization was 2.062 billion tons, the disposal was 943 million tons, and the storage in that year was 931 million tons. The output of straw in China is 805 million tons, and the utilization is 585 million tons. The output of general solid waste in Shanxi, Inner Mongolia, Hebei, Shandong and Liaoning provinces accounts for 42.4% of the country, and the comprehensive utilization of general industrial solid waste in Shandong, Hebei, Shanxi, Anhui and Jiangsu provinces accounts for about 40% of the country.
Third, the archives of key pollution sources and the pollution source information database have been improved.This census has formed a unified database for the second national pollution source census, with more than 1,800 database tables, 15,000 data fields and 150 million data records, forming a "one map" for the second national pollution source census. According to the requirements of the management method of pollution source census files, all files have been managed in an orderly manner and stored safely.
Fourthly, a group of business backbones with the spirit of environmental protection iron army have been trained.In the census work, enumerators and census instructors at all levels carry forward the spirit of environmental protection iron army, work hard and work hard. Through systematic training and on-site investigation, they understand the production technology, pollution control technology and environmental protection facilities of key industries and enterprises, and master the accounting methods of various pollutant emissions. In the process of summarizing the census results, through analysis and induction, we have grasped the environmental policy and the current environmental situation, and have been comprehensively studied and improved. Through the census, a group of comprehensive talents with high sense of responsibility and dedication, familiar with policies and proficient in business have been trained.
Fifth, the environmental awareness of the whole people has been further improved.The census took a long time, lasting three years. During the whole census period, through multi-media and multi-way publicity, the majority of friends in the press gave strong support, widely mobilized all sectors of society and actively participated in the census work, which improved the environmental awareness of the whole society and created a good atmosphere for the census. This is the main result of this census.
