Overview
Anhui wastewater treatment plant serves He County in Anhui, China, with a population of 150,000. It operates under China's national wastewater regulations.
The Anhui wastewater treatment plant is located in He County (和县), within the Ma'anshan prefecture of Anhui Province, China. The facility serves a population of approximately 150,000 people, classifying it as a medium-to-large agglomeration under Chinese wastewater management standards. As a plant of this scale in China, it is expected to meet the discharge standards set by the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). This regulation typically requires secondary biological treatment with nutrient removal for plants serving over 100,000 people, especially those discharging into sensitive water bodies. The plant's treated effluent likely discharges into a local river within the Yangtze River basin, as He County is situated near the Yangtze River. The downstream environment includes the Yangtze River ecosystem, which supports diverse aquatic life and provides water for agriculture, industry, and drinking water for millions. Proper treatment is critical to prevent eutrophication and protect this vital waterway.
Environmental context
The plant is located inland, approximately 50 km from the coast, and its treated wastewater likely flows into a tributary of the Yangtze River, which eventually reaches the East China Sea. The Yangtze River basin is ecologically significant, supporting numerous fish species and providing critical habitat for migratory birds. Nutrient pollution from untreated or inadequately treated wastewater can lead to algal blooms and oxygen depletion, threatening aquatic biodiversity and water quality downstream.
