Overview
Henan wastewater treatment plant serves Suiping County in Zhumadian City, Henan Province, China, with a population equivalent of 66,500. The facility operates under China's national wastewater discharge standards.
The Henan wastewater treatment plant is located in Suiping County, Zhumadian City, Henan Province, China. It serves a population equivalent of approximately 66,500, classifying it as a medium-sized municipal facility within the region's wastewater infrastructure. As a Chinese wastewater treatment plant, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for conventional pollutants and nutrients. For plants serving populations of this scale, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water body's sensitivity. The plant's treated effluent is discharged into local waterways that ultimately flow into the Huai River basin, a major river system in eastern China. The Huai River drains into the Yellow Sea via the Yangtze River estuary, supporting agricultural irrigation and aquatic ecosystems along its course. Proper treatment helps protect downstream water quality and biodiversity.
Environmental context
The plant discharges into tributaries of the Huai River basin, which flows through Henan and Anhui provinces before reaching the Yellow Sea. The Huai River supports diverse aquatic life and is a critical water source for agriculture and industry. Effective wastewater treatment is essential to prevent eutrophication and maintain ecological balance in this densely populated region.
