China News Agency, Beijing, June 10 (Reporter Chen Suo) "The Second National Pollution Source Census Bulletin" (hereinafter referred to as the "Gazette") was released on the 10th. The results of the census showed that between 2007 and 2017, China's pollutant emissions were substantial decline.
On the same day, the Information Office of the State Council held a press conference on the Communiqué. Zhao Yingmin, Vice Minister of the Chinese Ministry of Ecology and Environment, stated that the standard time for the first census of pollution sources was December 31, 2007, and the standard time for the second census was 2017. On December 31, there was a full difference of ten years. Compared with the first census, the emission of major pollutants in China dropped significantly.
In 2017, the discharge of pollutants such as sulfur dioxide, chemical oxygen demand, and nitrogen oxides decreased by 72%, 46%, and 34% respectively compared with 2007. While the output of products has increased significantly, the discharge of pollutants in key industries has dropped significantly. The chemical oxygen demand in the paper industry has decreased by 84%, the sulfur dioxide in the steel industry has decreased by 54%, and the nitrogen oxide in the cement industry has decreased by 23%.
Zhao Yingmin said that China's pollution control capacity has improved significantly in the past decade. The number of industrial enterprise wastewater treatment, desulfurization, dust removal and other facilities was 2.4 times, 3.3 times and 5 times that of 2007 respectively. The number of urban sewage treatment plants increased by 5.4 times, the treatment capacity increased by 1.7 times, and the actual sewage treatment capacity increased by 2.1 times. The number of domestic waste disposal plants increased by 86% in ten years, of which the number of waste incineration plants increased by 303%, and the proportion of incineration treatment volume increased from 8% a decade ago to 27%.
The "Gazette" shows that at the end of 2017, the number of various sources of pollution in China was 3.5832 million (excluding mobile sources), which basically showed a gradual decrease from east to west. Among them, Guangdong, Zhejiang, Jiangsu, Shandong, Hebei five types of pollution sources accounted for 52.94% of the national total.
From the perspective of the three major pollutant discharges, in terms of water pollutant discharge, the Yangtze River, Pearl River, and Huaihe River basins have a larger amount of pollutant discharge, and the Haihe, Liaohe, and Huaihe River basins have a greater intensity of pollutant discharge per unit of water resources; The emission intensity per unit area of air pollution sources in Beijing-Tianjin-Hebei and surrounding areas, the Yangtze River Delta, and the Fenwei Plain is relatively large; in terms of solid waste emissions, in 2017, the amount of general industrial solid waste generated was 3.868 billion tons. The production of general solid waste in the five provinces and autonomous regions of Shanxi, Inner Mongolia, Hebei, Shandong, and Liaoning accounted for 42.4% of the national total. (Finish)
