SMM Network News: since the State Council issued the "Action Plan for the Prevention and Control of Water pollution" (hereinafter referred to as the "10 Water articles") in April 2015, under the strong leadership of the CPC Central Committee and the State Council, the Ministry of Ecological Environment, together with various regions and departments, has taken improving the quality of the water environment as the core, coming out of Taiwan with supporting policies and measures, speeding up the control of water pollution, implementing various objectives and tasks, and effectively solving water pollution problems of concern to the masses. The overall water environment quality throughout the country has maintained a momentum of continuous improvement.
First, the discharge of water pollutants should be controlled in an all-round way. By the end of 2018, 97.4% of the industrial agglomeration areas at or above the provincial level had built centralized sewage treatment facilities and installed automatic on-line monitoring devices. 78% of the anti-seepage transformation of underground oil tanks in gas stations has been completed. Dismantle more than 10 million tons of old transport vessels and dismantle and transform 42500 inland river vessels. 4332 sewage treatment plants have been completed and operated in cities and towns throughout the country, with a sewage treatment capacity of 195 million cubic meters per day. A total of more than 262000 livestock and poultry farms (communities) in the forbidden area were closed or relocated, and 5628 demonstration farms for healthy aquaculture were established. A total of 163000 villages have carried out comprehensive improvement of the rural environment, and Zhejiang's "demonstration of thousands of villages and renovation of ten thousand villages" won the 2018 United Nations Earth Guard Award.
The second is to make every effort to ensure the security of water ecological environment. We promoted the environmental renovation of centralized drinking water sources throughout the country, completed 99.9 percent of 6251 problems in 1586 water sources, relocated 3740 industrial enterprises, closed 1883 sewage outlets, and improved the level of drinking water safety for 550 million residents. Of the 1062 black and smelly water bodies in 36 key cities (municipalities directly under the Central Government, provincial capitals and municipalities separately listed on the State plan), 1009 eliminated or basically eliminated black odour, accounting for 95% of the total, and the sense of access of the people around them was significantly enhanced. We will strengthen the prevention and control of blue-green algae blooms in key lakes such as Taihu Lake and Dianchi Lake. Eleven coastal provinces have formulated and implemented plans for the prevention and control of pollution in inshore waters at the provincial level to promote the prevention and control of marine waste (microplastic) pollution.
Third, linkage and cooperation to promote pollution control in the river basin. The river (lake) length system has been established in an all-round way, with a total of more than 300,000 river length and 24000 lake length at the provincial, municipal, county and township levels. We have set up a joint research center for the protection and restoration of the ecological environment of the Yangtze River, and 11 provinces (cities) of the Yangtze River Economic Belt and Qinghai Province have compiled and completed the "three lines and one single" (ecological protection red line, environmental quality bottom line, resource utilization online and ecological environment access list). The Chishui River and other river basins have carried out pilot projects to set up environmental supervision and administrative law enforcement agencies according to the river basins. Xinanjiang, Jiuzhou River, Ting River-Hanjiang, Dongjiang, Luanhe River, Chaobai River and other upstream and downstream provinces have established horizontal ecological compensation pilot projects.
Monitoring data show that in 2018, the proportion of excellent surface water quality (class Ⅰ-Ⅲ) and loss of use function (inferior class V) was 71.0% and 6.7%, respectively, which was 6.5 percentage points higher and 2.1 percentage points lower than that in 2015, respectively. the water quality has improved steadily. However, the situation of water pollution prevention and control is still grim, and there are still some outstanding problems in urban and rural environmental infrastructure construction, nitrogen and phosphorus and other nutrients control, watershed water ecological protection and so on.
In 2018, Beijing, Tianjin, Hebei, Shanghai, Zhejiang, Fujian, Jiangxi, Hubei, Guangxi, Hainan, Chongqing, Sichuan, Tibet, Gansu, Qinghai, Ningxia and Xinjiang have achieved better water environmental quality targets.
