Overview
Henan wastewater treatment plant serves Nanle County in Henan Province, China, with a population of approximately 50,800. The plant operates under China's national wastewater discharge standards.
The Henan wastewater treatment plant is located in Nanle County, Puyang City, Henan Province, China. It serves a population of approximately 50,800, placing it in the medium-sized agglomeration category. The plant is situated inland, away from coastal areas, and its operations are part of the broader municipal wastewater infrastructure for the region. Under China's national regulations, wastewater treatment plants serving populations of this scale are typically required to meet Class 1-A or 1-B discharge standards under the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). These standards mandate secondary treatment with nutrient removal for sensitive water bodies. It is expected to comply with these national standards. The treated effluent from the plant is likely discharged 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 includes agricultural areas and eventually flows into the Bohai Sea. Proper treatment is crucial to protect water quality and aquatic ecosystems in the region.
Environmental context
The plant discharges into a local waterway that is part of the Hai River or Yellow River basin, both of which drain into the Bohai Sea. The region supports agricultural irrigation and freshwater ecosystems. Effective nutrient removal is important to prevent eutrophication in downstream rivers and coastal waters, which are ecologically sensitive areas for fisheries and biodiversity.
