Overview
Hunan wastewater treatment plant serves Yanling County, Zhuzhou, Hunan, China, with a population of 68,300. It operates under China's national wastewater discharge standards.
Hunan wastewater treatment plant is located in Yanling County, Zhuzhou City, Hunan Province, China. The facility serves a population of approximately 68,300, placing it in the medium-sized agglomeration category for Chinese municipal wastewater infrastructure. As a Chinese municipal plant, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants, nutrients, and pathogens. For plants serving populations of this scale, secondary biological treatment is typically required, with potential nutrient removal in sensitive watersheds. The plant's treated effluent is discharged into local waterways that eventually drain into the Xiang River system, a major tributary of the Yangtze River. The Xiang River basin supports diverse aquatic life and provides water for agriculture and industry in Hunan Province. Proper treatment helps protect downstream water quality and ecological health.
Environmental context
The plant discharges into local streams that flow into the Xiang River, a major tributary of the Yangtze River. The Xiang River basin supports diverse aquatic ecosystems and provides water for agriculture and industry. The region's subtropical climate with high rainfall can increase runoff and pollutant loading, making effective treatment crucial for maintaining downstream water quality and ecological balance.
