Our country will focus on improving the wastewater treatment in industrial parks along the Yangtze River Economic Belt, in order to enhance quality and efficiency overall, strengthen ecological environment protection, and resolutely combat pollution. At the 4th annual meeting of the \"Belt and Road\" Ecological and Environmental Protection Big Data Service Platform and International Intelligence Hub for Environmental Protection Technologies, hosted by the Center for International Cooperation and Exchange under the Ministry of Ecology and Environment this morning, Hong Yuning, a doctor from the Water Pollution Sources Division of the Department of Water Ecology and Environment at the Ministry, explained that there are currently 552 development zones of various levels across the country, with over 2,400 industrial parks that discharge industrial wastewater. Earlier on, the Ministry of Ecology and Environment urged industrial parks at the provincial level and above across the country to implement the requirements set out in the Water Pollution Prevention and Control Plan. 58% of these parks have established centralized wastewater treatment facilities, while 97% have installed automatic online monitoring systems. The capacity for wastewater treatment in these industrial parks has increased by more than 28.6 million tons per day. At present, there are mainly three issues regarding the prevention and control of water pollution in industrial parks in our country: the infrastructure in a few parks is inadequate and incomplete ； Inadequate construction and maintenance of pipeline networks ； The design and operation of centralized wastewater treatment facilities are unscientific and unreasonable.

In the Yangtze River Economic Belt, the situation regarding water pollution control in industrial parks is not optimistic. The Yangtze River Economic Belt is one of the river basins in China where water environment problems are most severe. Monitoring data show that although the Yangtze River Economic Belt accounts for only 21% of the country’s total area, it generates over 40% of the country’s total wastewater discharge. The emission levels of chemical oxygen demand, ammonia nitrogen, sulfur dioxide, nitrogen oxides, and volatile organic compounds per unit area are 1.5 to 2 times higher than the national average.
The Yangtze River serves as a source of drinking water for many provinces and cities along its banks; the safety of this drinking water is relevant to the health of over 500 million people. Trace toxic pollutants in the water can pose threats to human health and the aquatic ecosystem through the food chain. Taking the chemical parks in the Yangtze River Economic Belt as an example, according to Yang Ting, secretary-general of the Chemical Parks Working Committee of the China Petroleum and Chemical Industry Federation, there are currently 676 key chemical parks in China, whose total output value accounts for about 60% of the total output value of the country’s petroleum and chemical industry. Chemical parks have truly become the \"main battlefield\" for the development of China’s petrochemical industry. With so many chemical industrial parks, the quality of their development varies; therefore, \"improving quality and efficiency as well as pursuing green development is of utmost importance.\"
It’s never too late to take action; the longer you wait, the greater the cost.
The water in the upper reaches of the Yangtze River is noticeably cleaner
