Overview
Hubei wastewater treatment plant serves Shishou City, Hubei Province, China, with a population equivalent of 147,000. The plant discharges into local waterways within the Yangtze River basin.
The Hubei wastewater treatment plant is located in Shishou City, Jingzhou Prefecture, Hubei Province, China. It serves a population equivalent of 147,000, classifying it as a large agglomeration under Chinese wastewater regulations. The plant is situated inland, approximately 50 km from the coast, and its treated effluent ultimately drains into the Yangtze River basin. China's wastewater treatment standards for large agglomerations typically require secondary treatment with nutrient removal, in line with the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). The plant operates under the regulatory framework of the Ministry of Ecology and Environment, which mandates compliance with effluent limits for biochemical oxygen demand, chemical oxygen demand, suspended solids, and nutrients. The receiving water body is part of the Yangtze River system, which flows eastward into the East China Sea. The Yangtze basin supports diverse aquatic life and provides water for millions of people. Proper treatment at this plant helps protect downstream water quality and ecological health in the middle and lower reaches of the river.
Environmental context
The plant discharges into local tributaries of the Yangtze River, which flows through central China before emptying into the East China Sea. The Yangtze basin is a critical freshwater ecosystem supporting numerous fish species and migratory birds. Effective wastewater treatment is essential to prevent eutrophication and maintain water quality in this densely populated and ecologically significant watershed.
