Overview
Hubei wastewater treatment plant serves Zhongxiang City, Hubei Province, China, with a population equivalent of 190,000. It discharges into local waterways under China's national wastewater standards.
The Hubei wastewater treatment plant is located in Zhongxiang City, within Jingmen Prefecture, Hubei Province, China. It serves a population of approximately 190,000, classifying it as a medium-to-large agglomeration under Chinese municipal wastewater management. The plant is situated inland, away from coastal areas, and its operations are part of the regional water infrastructure for the Han River basin. As a facility serving a population of 190,000, the plant is expected to meet the discharge standards set by China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). This national regulation mandates secondary treatment as a minimum, with more stringent requirements for sensitive water bodies. Typical facilities of this scale employ biological treatment methods such as activated sludge or oxidation ditch. The treated effluent from the plant is discharged into local watercourses that ultimately flow into the Han River, a major tributary of the Yangtze River. The Han River supports diverse aquatic life and provides water for agriculture and industry in Hubei Province. Downstream, the Yangtze River flows into the East China Sea, making the plant's performance important for both regional water quality and the broader Yangtze ecosystem.
Environmental context
The plant discharges into local streams that drain into the Han River, a major tributary of the Yangtze River. The Han River basin supports diverse aquatic ecosystems and is an important water source for agriculture and industry in central China. Downstream, the Yangtze River flows into the East China Sea, making nutrient and pollutant control critical for preventing eutrophication and protecting estuarine habitats.
Frequently asked questions
The Hubei wastewater treatment plant is located in Zhongxiang City, Jingmen Prefecture, Hubei Province, China.
The plant serves a population of approximately 190,000 people, classifying it as a medium-to-large municipal wastewater treatment facility.
The plant discharges into local watercourses that flow into the Han River, a major tributary of the Yangtze River, ultimately reaching the East China Sea.
The plant operates under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for pollutants like COD, BOD, and nutrients. For a facility of this scale, secondary treatment is typically required.
Plants of this scale in China commonly use biological treatment processes such as activated sludge, anaerobic-anoxic-oxic (A2O), or sequencing batch reactors (SBR) to meet national discharge standards.
