Major Announcement: Ten Ministries Jointly Issue "Guiding Opinions on Promoting Wastewater Resource Utilization"

Recently, ten ministries including the National Development and Reform Commission, the Ministry of Ecology and Environment, the Ministry of Science and Technology, and the Ministry of Industry and Information Technology jointly issued the Guiding Opinions on Promoting the Resource Utilization of Wastewater (hereinafter referred to as the Opinions). The Opinions put forward opinions on the resource utilization of industrial wastewater, pointing out that: conducting enterprise water use audits, water efficiency benchmarking, and water-saving transformation; promoting internal industrial water recycling in enterprises to improve the reuse rate; promoting the integrated optimization of water use systems among enterprises within industrial parks to achieve integrated improvement; improving the construction of industrial enterprise and park wastewater treatment facilities; improving operation and management levels to ensure that industrial wastewater meets discharge standards; and carrying out the reuse of industrial wastewater.

Resource utilization technology for colored metallurgical acidic wastewater

Resource utilization technology for colored metallurgical acidic wastewater

Colored metal wastewater can be divided into acidic wastewater, alkaline wastewater, heavy metal wastewater, cyanide-containing wastewater, and oil-containing wastewater, etc. Acidic wastewater contains a large amount of heavy metal ions such as sulfuric acid, lead, zinc, copper, arsenic, and iron. If this wastewater is discharged into the environment without treatment, it will cause a decrease in the pH value of the water body, affecting the survival environment of aquatic plants and animals, and destroying the ecological balance. Heavy metal ions will accumulate in the bodies of plants and animals and harm human health through the food chain. Some substances in wastewater can be utilized; as long as suitable processes are explored, they are resources. This article takes the acidic wastewater of a certain smelting plant as an example, combined with the treatment methods of non-ferrous metallurgy wastewater, will
