Overview
Hunan wastewater treatment plant serves Taojiang County in Hunan Province, China, with a population equivalent of 108,000. The facility discharges into local waterways within the Yangtze River basin.
The Hunan wastewater treatment plant is located in Niutanhe Community, Taojiang Town, Taojiang County, Hunan Province, China. It serves a population equivalent of 108,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management standards. As a municipal facility in China, the plant operates under national discharge standards (GB 18918-2002) which mandate secondary treatment for urban wastewater. For plants serving over 100,000 people, enhanced treatment may be required to meet local water quality objectives, particularly in sensitive watersheds. The plant's treated effluent enters local rivers that ultimately drain into the Yangtze River basin. The downstream environment supports diverse aquatic ecosystems and provides water for agricultural and industrial use. Proper treatment is critical to prevent eutrophication and protect downstream communities.
Environmental context
The plant discharges into local watercourses within the Zi River system, a tributary of the Yangtze River. The downstream environment includes agricultural lands and wetlands that rely on good water quality. The Yangtze basin is ecologically significant, supporting numerous fish species and providing water for millions of people. Effective wastewater treatment helps reduce nutrient loading and protect aquatic habitats.
