Overview
Hubei wastewater treatment plant serves 41,000 people in Zhijiang, Hubei, China. The facility operates under China's national wastewater standards for urban agglomerations.
The Hubei wastewater treatment plant is located in Zhijiang, a city in Yichang prefecture, Hubei Province, China. The facility serves a population of approximately 41,000, placing it in the medium-sized agglomeration category under Chinese wastewater regulations. China's wastewater treatment standards require secondary treatment for urban plants serving populations above 10,000, with stricter nutrient removal in sensitive watersheds. Facilities of this scale typically employ activated sludge or similar biological treatment systems. The plant discharges into local waterways that ultimately drain into the Yangtze River basin, one of China's most ecologically and economically significant river systems. The Yangtze supports diverse aquatic life and provides water for millions of people downstream.
Environmental context
The plant's treated effluent enters local streams that flow into the Yangtze River, China's longest river, which empties into the East China Sea near Shanghai. The Yangtze basin is a critical freshwater ecosystem supporting numerous fish species and providing irrigation for extensive agricultural areas. Nutrient loading from upstream sources can contribute to algal blooms in downstream lakes and coastal zones.
Frequently asked questions
The Hubei wastewater treatment plant is located in Zhijiang, a city in Yichang prefecture, Hubei Province, China. The address is Baiyun Road, Yunchi Street, Zhijiang.
The Hubei wastewater treatment plant serves approximately 41,000 people, classifying it as a medium-sized urban wastewater facility.
The plant treats wastewater that would otherwise enter local streams and rivers within the Yangtze River basin. By treating the water, it helps protect the Yangtze River and its downstream ecosystems.
China's wastewater treatment standards, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), require secondary treatment for urban plants serving populations above 10,000. Plants in sensitive areas may need advanced treatment for nutrient removal.
For a medium-sized agglomeration of 41,000 people in China, typical treatment includes secondary biological processes such as activated sludge, oxidation ditches, or sequencing batch reactors. Many plants also incorporate disinfection and, in sensitive watersheds, nutrient removal.
