Overview
Henan wastewater treatment plant serves Zhumadian, Henan province, China, with a population equivalent of 312,000. It operates under China's national wastewater discharge standards.
Henan wastewater treatment plant is located in Zhumadian, Henan province, China, serving a population equivalent of 312,000. The plant is situated in the Jinqiao subdistrict of Yicheng district, within the urban area of Zhumadian. As a medium-to-large agglomeration, it plays a key role in managing municipal wastewater for the region. Under China's national wastewater discharge standards (GB 18918-2002), plants serving populations over 100,000 are typically required to achieve at least secondary treatment, with stricter limits for sensitive water bodies. Regulatory expectations for this scale of facility emphasize nutrient removal and compliance with Class 1A or 1B discharge standards. The plant discharges into the local water system, which ultimately drains into the Huai River basin. The Huai River is a major waterway in eastern China, flowing into the Yellow Sea. Downstream ecosystems rely on adequate treatment to prevent eutrophication and protect aquatic biodiversity, particularly in the Huai River's floodplain and wetlands.
Environmental context
The plant's receiving waters flow into the Huai River basin, a major watershed in eastern China that drains into the Yellow Sea. The Huai River supports diverse aquatic life and is an important water source for agriculture and industry. Downstream areas include ecologically sensitive floodplains and wetlands that require protection from nutrient pollution and industrial contaminants.
