Overview
Henan wastewater treatment plant serves Tangyin County in Henan Province, China, with a population of 93,500. The plant operates under China's national wastewater standards.
The Henan wastewater treatment plant is located in Tangyin County, Anyang City, Henan Province, China. It serves a population of approximately 93,500, classifying it as a medium-sized municipal facility within the region's wastewater infrastructure. As a Chinese treatment plant, 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 sensitivity. For plants of this scale, secondary treatment with nutrient removal is typically required to meet Class 1A or 1B standards, especially if discharging into sensitive water bodies. The plant's treated effluent likely discharges into local waterways that eventually flow into the Hai River system, which drains into the Bohai Sea. The region's water resources are under pressure from agricultural and industrial activities, making effective wastewater treatment crucial for protecting downstream aquatic ecosystems and water quality.
Environmental context
The plant discharges into local tributaries of the Hai River basin, which flows through Henan and Hebei provinces before reaching the Bohai Sea. The downstream environment supports diverse aquatic life and is important for regional water supply. Effective treatment helps mitigate eutrophication risks in the Bohai Sea, which experiences seasonal algal blooms due to nutrient loading from multiple sources.
