Hubei Wastewater Treatment Plant, Liuli Ping Zhen, Shiyan, Hubei, China

The Hubei wastewater treatment plant is located in Liuli Ping Zhen, Danjiangkou City, Shiyan, Hubei Province, China. It serves a population of approximately 33,000 people, classifying it as a medium-sized municipal facility within the region's wastewater infrastructure. As a Chinese wastewater treatment plant, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits based on the receiving water body's sensitivity. For plants serving populations around 33,000, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, especially in environmentally sensitive areas. The plant's treated effluent likely discharges into a local waterway that flows into the Danjiangkou Reservoir, a key water source for the South-North Water Transfer Project. This reservoir supports aquatic ecosystems and provides drinking water to millions downstream, making effective treatment critical for protecting water quality and public health.

The plant is situated in the Danjiangkou Reservoir watershed, which feeds into the Han River, a major tributary of the Yangtze River. The reservoir is a critical water source for the South-North Water Transfer Project, supplying drinking water to northern China. Downstream aquatic life and water quality depend on effective nutrient and pollutant removal to prevent eutrophication and maintain ecological balance in this sensitive freshwater system.
