Overview
Hunan wastewater treatment plant serves Chaling County in Zhuzhou, Hunan, China, with a population equivalent of 135,000. The facility operates under China's national wastewater discharge standards.
The Hunan wastewater treatment plant is located in Chaling County, Zhuzhou City, Hunan Province, China. It serves a population equivalent of 135,000, classifying it as a medium-to-large agglomeration under Chinese municipal wastewater management frameworks. As a plant serving over 100,000 people, it is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates secondary treatment with nutrient removal for sensitive water bodies. The facility's operational context aligns with China's national water pollution control policies under the Water Pollution Prevention and Control Law. The plant discharges treated effluent into local waterways that ultimately drain into the Yangtze River basin via the Xiang River system. This region supports diverse aquatic ecosystems and is important for downstream water quality in the middle Yangtze floodplain. Proper treatment helps protect these waters from eutrophication and other pollution impacts.
Environmental context
The plant's treated effluent flows into tributaries of the Xiang River, a major tributary of the Yangtze River. The Xiang River basin supports diverse aquatic life and provides water for agriculture and drinking. Downstream, the Yangtze River estuary and East China Sea receive the cumulative discharge, making nutrient removal critical to prevent algal blooms and hypoxia in coastal waters.
