Overview
Hunan wastewater treatment plant serves Kaifu District, Changsha, China, with a population of 380,000. It operates under China's national wastewater standards.
The Hunan wastewater treatment plant is located in Kaifu District, Changsha, Hunan Province, China. It serves a population of approximately 380,000 people, making it a large-scale municipal facility within the region. As a major treatment plant in China, it is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets stringent limits on effluent quality. For plants of this size, advanced treatment is often required to meet Class 1A standards, especially in sensitive watersheds. The plant discharges treated effluent into the local water system, which ultimately drains into the Xiang River, a tributary of the Yangtze River. The Xiang River supports diverse aquatic life and provides water for agricultural and industrial use downstream. Proper treatment is critical to protect the river's ecological health and the Yangtze River basin.
Environmental context
The plant's treated effluent flows into the Xiang River, which is a major tributary of the Yangtze River. The Xiang River basin supports a variety of freshwater species and is an important water source for the region. Downstream, the Yangtze River is one of the world's most biodiverse rivers, hosting numerous fish species and providing critical habitat for migratory birds. Effective wastewater treatment helps prevent eutrophication and maintains water quality in this ecologically significant system.
