Overview
Hubei wastewater treatment plant serves Lichuan City in Hubei Province, China, with a population equivalent of 120,000. The facility operates under China's national wastewater discharge standards.
The Hubei wastewater treatment plant is located in Lichuan City, within the Enshi Tujia and Miao Autonomous Prefecture of Hubei Province, China. Serving a population of approximately 120,000, the plant is a medium-to-large municipal facility in the mountainous region of southwestern Hubei. China's wastewater treatment standards, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), set effluent limits based on receiving water body sensitivity. For plants of this scale, secondary treatment with nutrient removal is typical, and many facilities in the region are being upgraded to meet stricter Class 1A standards to protect downstream water quality. The plant discharges into the local watershed, which ultimately drains into the Yangtze River via the Qingjiang River system. The Yangtze River basin supports diverse aquatic ecosystems and provides drinking water for millions. Effective treatment at this plant helps reduce nutrient and pollutant loads to the river, supporting ecological health and water quality goals.
Environmental context
The plant's treated effluent flows into the Qingjiang River, a tributary of the Yangtze River. The Yangtze River basin is one of the world's most biodiverse freshwater ecosystems, hosting numerous fish species and migratory birds. Downstream, the river passes through densely populated areas before reaching the East China Sea. Nutrient and pollutant control at this plant is critical to preventing eutrophication and protecting aquatic life in the Yangtze River system.
