Overview
Henan wastewater treatment plant serves Huixian City in Henan Province, China, with a population equivalent of 155,000. The facility operates under China's national wastewater discharge standards.
The Henan wastewater treatment plant is located in Huixian City, Xinxiang, Henan Province, China. It serves a population equivalent of 155,000, classifying it as a medium-to-large agglomeration under Chinese municipal wastewater management. The plant is situated in the inland region of northern Henan, an area characterized by agricultural and industrial activity. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), mandate secondary treatment with nutrient removal for plants of this scale. The facility likely employs an activated sludge process or similar biological treatment to meet these standards. Effluent quality is monitored to comply with local environmental protection requirements. The treated wastewater is discharged into the local water system, which ultimately drains into the Hai River basin. The Hai River system flows eastward through the North China Plain and discharges into the Bohai Sea. The plant plays a critical role in protecting downstream water quality, supporting aquatic life, and reducing pollution loads to the Bohai Sea ecosystem.
Environmental context
The plant discharges into the Hai River basin, which flows through the North China Plain and empties into the Bohai Sea. This watershed supports diverse aquatic habitats and is an important migratory corridor for fish and birds. The Bohai Sea is a semi-enclosed water body sensitive to nutrient pollution, making effective wastewater treatment essential for preventing eutrophication and maintaining ecological balance.
