Overview
Hunan wastewater treatment plant serves Tianxin District, Changsha, China, with a population of 560,000. The facility operates under China's national wastewater standards.
The Hunan wastewater treatment plant is located in Tianxin District, Changsha, Hunan Province, China. It serves a population of approximately 560,000, classifying it as a large-scale municipal facility within the urban area of Changsha. As a major treatment plant in China, it is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for conventional pollutants and nutrients. For plants of this scale, advanced treatment (tertiary) is often required to meet stricter local standards, especially in sensitive watersheds. The treated effluent is discharged into the Xiang River, a major tributary of the Yangtze River, which flows into Dongting Lake and ultimately the East China Sea. The plant plays a critical role in protecting the Xiang River's water quality and the downstream aquatic ecosystem in the Yangtze basin.
Environmental context
The plant discharges into the Xiang River, which flows into Dongting Lake and then the Yangtze River, eventually reaching the East China Sea. The Xiang River supports diverse aquatic life and is an important water source for the region. The plant's discharge must comply with stringent nutrient limits to prevent eutrophication in Dongting Lake, a large freshwater lake with significant ecological importance.
