Overview
Hunan wastewater treatment plant serves Hongjiang Management District in Hunan Province, China, with a population of 71,000. The facility discharges treated effluent into local waterways within the Yangtze River basin.
The Hunan wastewater treatment plant is located in the Hongjiang Management District of Hongjiang City, Huaihua, Hunan Province, China. It serves a population of approximately 71,000 people, placing it in the medium agglomeration category. The plant is situated in a mountainous region near the Yuan River, a tributary of the Yangtze River. As a Chinese municipal wastewater facility, the plant operates under national standards such as the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). For plants serving populations over 50,000, Chinese regulations typically require secondary treatment with nutrient removal to meet Class 1A or 1B effluent standards, especially in sensitive watersheds. The treated effluent is discharged into local water bodies that flow into the Yuan River, which eventually joins the Yangtze River. The Yangtze basin supports diverse aquatic life and provides water for millions of people. Proper treatment is essential to protect downstream ecosystems and water quality in this densely populated region.
Environmental context
The plant discharges into the Yuan River system, a major tributary of the Yangtze River. The Yangtze basin is ecologically significant, supporting numerous fish species and providing critical habitat for migratory birds. Downstream waters flow through Hunan's agricultural and industrial areas before reaching Dongting Lake, a large freshwater lake that regulates floodwaters and sustains biodiversity. Effective wastewater treatment helps prevent eutrophication and protects water quality in this interconnected river-lake system.
