Overview
Henan wastewater treatment plant serves Neihuang County in Anyang, Henan Province, China. The facility treats wastewater for approximately 86,000 residents, supporting local water quality in the region.
The Henan wastewater treatment plant is located in Baluzhuang Village, Neihuang County, Anyang City, Henan Province, China. It serves a population of approximately 86,000 people, classifying it as a medium-sized agglomeration under typical municipal wastewater management frameworks. China's wastewater treatment standards are governed by the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits based on the receiving water body's sensitivity. For plants serving populations of this scale, secondary treatment with nutrient removal is commonly required to meet Class 1A or 1B standards, especially in regions with environmental sensitivity. The plant's treated effluent likely discharges into a local river or waterway within the Hai River basin or Yellow River basin, as Henan Province is part of these major drainage systems. The downstream environment supports agricultural irrigation and aquatic ecosystems, making effective treatment crucial for preventing eutrophication and protecting water resources in the region.
Environmental context
The plant is situated inland in Henan Province, within the broader drainage basin of the Yellow River or Hai River systems. Treated wastewater likely flows into local tributaries that eventually reach the Yellow Sea via the Yellow River or Bohai Sea via the Hai River. The region's water bodies support agricultural irrigation and freshwater biodiversity, requiring effective nutrient removal to prevent algal blooms and maintain water quality.
