Overview
Hunan wastewater treatment plant serves Jingzhou County in Hunan, China, with a population of 83,800. The facility operates under China's national wastewater discharge standards.
The Hunan wastewater treatment plant is located in Jingzhou County, Huaihua City, Hunan Province, China. It serves a population of approximately 83,800, placing it in the medium-sized agglomeration category for Chinese municipal wastewater infrastructure. Under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), plants serving this population tier are typically required to meet Class 1A or 1B standards, which mandate biological treatment with nutrient removal. The regulatory framework ensures compliance with national effluent limits. The plant discharges treated wastewater into local water bodies within the Yuan River basin, which flows into Dongting Lake and ultimately the Yangtze River. This downstream chain supports diverse aquatic life and provides water for agricultural and industrial use in the region.
Environmental context
The plant's treated effluent enters the Yuan River system, a tributary of Dongting Lake, which is a major regulating lake for the Yangtze River. The watershed supports extensive rice paddies and fisheries, making nutrient control critical to prevent eutrophication in downstream lakes and rivers.
