Overview
Henan wastewater treatment plant serves Qinyang City, Henan Province, China, with a population of 115,000. It operates under China's national wastewater standards for urban agglomerations.
The Henan wastewater treatment plant is located in Qinyang City, within Henan Province, China. Serving a population of 115,000, it is classified as a medium-to-large agglomeration under Chinese wastewater regulations, which require secondary treatment for urban areas of this scale. As a facility in China, the plant is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for conventional pollutants and nutrients. For agglomerations serving over 100,000 people, advanced treatment (tertiary) is often mandated in sensitive watersheds to reduce nitrogen and phosphorus loads. The plant discharges into the local water system within the Yellow River basin, one of China's major river systems. The Yellow River and its tributaries support extensive agricultural irrigation and provide drinking water for millions. Proper treatment is critical to prevent eutrophication and protect downstream aquatic ecosystems and human water uses.
Environmental context
The plant is situated in the Yellow River basin, which drains into the Bohai Sea. The Yellow River is a vital water source for northern China, supporting agriculture, industry, and domestic use. Downstream ecosystems include wetlands and riverine habitats that are important for migratory birds and fish. Nutrient pollution from wastewater can contribute to algal blooms and hypoxia in the Bohai Sea, making effective treatment essential for regional environmental health.
