Overview
Henan wastewater treatment plant serves Qingfeng County, Henan, China, with a population of 61,500. It operates under China's national wastewater standards for medium-sized agglomerations.
The Henan wastewater treatment plant is located in Qingfeng County, Puyang City, Henan Province, China. It serves a population of approximately 61,500, classifying it as a medium-sized municipal facility within the region's wastewater infrastructure. As a plant in China, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits based on receiving water body sensitivity. For medium-sized agglomerations like this, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, especially if discharging into sensitive water bodies. The plant's treated effluent likely discharges into a local river within the Hai River basin or a tributary of the Yellow River, given the geographic location. Downstream, the water eventually reaches the Bohai Sea, making proper treatment crucial for protecting coastal water quality and aquatic ecosystems in the region.
Environmental context
The plant is located inland in Henan Province, within the drainage basin of the Yellow River or its tributaries. Treated wastewater likely flows into local waterways that eventually reach the Bohai Sea. The region supports agricultural activities and diverse aquatic life, so effective nutrient removal is important to prevent eutrophication in downstream rivers and coastal zones.
