Overview
Hunan wastewater treatment plant serves Lingxi Town in Yongshun County, Xiangxi Prefecture, Hunan Province, China. It serves a population of 149,500, operating under China's national wastewater standards.
The Hunan wastewater treatment plant is located in Lingxi Town, Yongshun County, within the Xiangxi Tujia and Miao Autonomous Prefecture of Hunan Province, China. The facility serves a population of approximately 149,500, placing it in the medium-to-large agglomeration category for Chinese municipal wastewater infrastructure. As a plant serving a population of this scale, it is expected to comply with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates secondary treatment as a baseline and may require advanced treatment in sensitive watersheds. Typical facilities in this region employ activated sludge processes with nutrient removal to meet Class 1A or 1B discharge standards. The plant discharges treated effluent into local water bodies within the Yuan River basin, which flows into Dongting Lake and ultimately the Yangtze River. This watershed supports diverse aquatic life and provides water for agriculture and communities downstream. Proper treatment is critical to protect water quality in this ecologically sensitive region.
Environmental context
The plant's effluent enters the Yuan River system, a tributary of Dongting Lake, which is a major freshwater lake in the Yangtze River basin. Dongting Lake is an ecologically significant area that supports migratory birds, fish spawning, and wetland biodiversity. The lake also regulates floodwaters and supplies water for irrigation and drinking. Effective wastewater treatment is essential to prevent nutrient pollution and maintain the ecological health of this downstream environment.
