Why is it better to improve the quality of the water environment?
time:2023-11-22 17:42:27      click:959

"The discharge of major pollutants, whether water or air, is more than 20 million tons, far exceeding the environmental capacity. A few percentage points of the decline since the 11th Five-Year Plan is difficult to drive overall improvement in environmental quality." Ministry of Environmental Protection Vice Minister Yan Qing explained on the spot. If the environmental quality is required to change significantly, according to experts' estimates, the pollutant emissions will be reduced by 30% to 50% on the existing basis.

He also pointed out that the total amount of pollutants is not enough. Now only the chemical oxygen demand, ammonia nitrogen indicators, total phosphorus, total nitrogen and other related pollutants are not included.

These reasons have led the public to feel that there is a positive correlation between emissions reduction and environmental quality improvement.

In recent years, the serious situation of water pollution in China has not been fundamentally contained. In the national surface water control section, there are still nearly 1/10 (9.2%) loss of water use function (inferior to Category V) and 24.6% of key lakes ( The reservoir is in a state of eutrophication; many river ditches flowing through the town are black and smelly. Drinking water pollution incidents occur from time to time. Among the 4,778 groundwater quality monitoring points in the country, the proportion of poor monitoring points was 43.9%, and the proportion of extremely poor was 15.7%. Of the nine important bays in the country, six are poor or very poor.

Ma Zhong, dean of the School of Environment of Renmin University of China, pointed out that China's industrial wastewater discharge standards do not meet the surface water quality standards, and the COD concentrations of all emission standards are higher than the quality standard V water requirements, that is, the industrial standards are discharged. Waste water is inferior to Class V water.

According to expert analysis, the discharge standard of wastewater and the quality standard of surface water are out of the way, which is an important reason for the company to claim that the water quality is up to standard and the people think it causes pollution.

This urgently requires that the water environment management should complete the transformation from total control to quality target management as soon as possible, and improve environmental quality as the ultimate standard for judging the effectiveness of various work.

In order to make the masses visible and enjoy the results of the improvement of the water environment, “Water 10” proposes that by 2020, the proportion of the seven key river basins with excellent water quality (achieving or better than Class III) will reach over 70%, and the prefecture level and above. The black and odorous water bodies in the urban built-up area are all controlled within 10%, and the water quality of the centralized drinking water sources at or above the prefecture level is higher than or equal to the proportion of the third category, which is higher than 93%.

In fact, taking the improvement of the quality of the water environment that the masses are concerned about as an entry point, optimizing the economic structure and transforming the mode of economic development, initial results have been achieved in some places.

Zhejiang Province took the "five-water joint governance" as a breakthrough, and forced the transformation and upgrading, with remarkable results. According to a survey by the Zhejiang Provincial Bureau of Statistics, 83.9% of the public in 2014 were satisfied with the local ecological environment, an increase of 1.66 percentage points over the previous year.

Similarly, the improvement of water environment quality has also been reflected in water resources management. The assessment of water resources management has been tightened year by year, showing that the country is striving to change the current problems of over-exploitation of water resources, water wastage, and serious water pollution. The determination to reverse the deterioration of the water environment from the source is increasing, the intensity is increasing, and the water is pushed. The need to improve environmental quality is even more urgent.

This also shows that China's water environment management is changing. In the future, water environment management must be considered as a whole. The improvement of water environment quality should be the core, and water resources management, water pollution control and water ecological protection should be promoted systematically.

This is a trend.

Chen Jining, Minister of the Ministry of Environmental Protection, said at the beginning of this year that environmental quality improvement is the core of environmental protection. It must be carried out with the utmost efforts to persevere and last for a long time. Every year, a group of people can be seen, touched and able to The benefits of governance will enable the people to truly feel that the environment can be better, pollution can be governed, and people's new expectations for environmental protection will be continuously met.

The era of environmental protection with the core of improving environmental quality and environmental governance has arrived.
