Overview
Henan wastewater treatment plant serves Wenfeng District, Anyang, Henan, China, with a population of 250,000. It operates under China's national wastewater standards for urban agglomerations of this scale.
The Henan wastewater treatment plant is located in Wenfeng District, Anyang, Henan Province, China. It serves a population of approximately 250,000, classifying it as a medium-to-large urban agglomeration under Chinese wastewater management frameworks. The facility is situated inland, away from coastal areas, and its operations are part of the municipal infrastructure for the region. As a plant serving 250,000 people, it is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets limits for key pollutants such as COD, BOD, ammonia nitrogen, and total phosphorus. For agglomerations of this size, secondary treatment with nutrient removal is typically required, especially if the receiving water body is in a sensitive area. The regulatory framework ensures compliance with national standards. The treated wastewater from the plant is discharged into a local water body, likely a tributary of the Hai River system, which flows into the Bohai Sea. The plant plays a crucial role in protecting downstream aquatic ecosystems and supporting water quality in the densely populated Henan region. Its operation contributes to reducing pollution loads in the Hai River basin, which is ecologically important for both freshwater and coastal environments.
Environmental context
The plant discharges into a local water body within the Hai River basin, which ultimately drains into the Bohai Sea. The Hai River system is heavily influenced by agricultural runoff and urban discharges, making wastewater treatment critical for controlling eutrophication and maintaining water quality. The downstream environment supports diverse aquatic life and provides water for irrigation and industrial use, highlighting the plant's role in regional ecological health.
