Overview
Henan wastewater treatment plant serves Nanyang, Henan, China, with a population equivalent of 136,400. It operates under China's national wastewater standards.
The Henan wastewater treatment plant is located in Yudu Subdistrict, Zhenping County, Nanyang City, Henan Province, China. It serves a population equivalent of 136,400, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. As a facility in China, the plant is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants, nutrients, and pathogens. For agglomerations of this scale, secondary treatment with nutrient removal is typically required, especially if the receiving water body is in a sensitive area. The plant's treated effluent likely discharges into a local waterway within the Yangtze River basin, as Nanyang is situated near the headwaters of the Han River, a major tributary of the Yangtze. The downstream environment supports diverse aquatic life and provides water for agricultural and municipal use, making effective treatment critical for ecological and public health.
Environmental context
The plant is located in the upper reaches of the Han River system, which flows into the Yangtze River. The Han River supports important fisheries and provides drinking water for millions downstream. The region's karst topography and seasonal rainfall patterns influence runoff and dilution capacity, making consistent treatment essential to prevent eutrophication and protect aquatic biodiversity.
