Overview
Hunan wastewater treatment plant serves Zhongfang County in Huaihua, Hunan, China, with a population of approximately 38,900. It operates under China's national wastewater standards for inland facilities.
The Hunan wastewater treatment plant is located in Zhongfang County, Huaihua City, Hunan Province, China. It serves a population of around 38,900, placing it in the medium-scale category for municipal wastewater treatment in the region. The facility is situated inland, away from coastal areas, and its operations are part of the broader water management infrastructure for the local urban area. As a Chinese wastewater treatment plant, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). This standard sets effluent limits for various pollutants and requires appropriate treatment levels based on the receiving water body's sensitivity. For a plant serving nearly 40,000 people, secondary treatment with nutrient removal is typically expected to protect local water quality. The plant discharges into the local watershed, which ultimately drains into the Yuan River, a tributary of the Yangtze River. The Yangtze River basin is ecologically significant, supporting diverse aquatic life and providing water for millions of people. Proper treatment at this facility helps reduce nutrient and pollutant loads entering the river system, contributing to the health of downstream ecosystems.
Environmental context
The plant's treated effluent flows into the Yuan River, a major tributary of the Yangtze River. The Yangtze River basin is one of the world's most biodiverse freshwater ecosystems, supporting numerous fish species and migratory birds. Effective wastewater treatment is crucial to prevent eutrophication and protect water quality in this ecologically sensitive watershed.
