Overview
Hubei wastewater treatment plant serves 180,000 people in Huanggang, Hubei, China. It operates under China's national wastewater standards, discharging treated effluent into local waterways.
The Hubei wastewater treatment plant is located in Macheng, a county-level city under Huanggang, Hubei Province, China. It serves a population of 180,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. China's wastewater treatment standards, governed by the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), require secondary treatment as a baseline, with stricter limits for sensitive areas. Plants of this scale typically employ biological treatment processes such as activated sludge or A2O to meet these standards. The treated effluent from the plant is discharged into local rivers that flow into the Yangtze River basin, eventually reaching the East China Sea. This downstream water body supports diverse aquatic life and is critical for regional water supply and agriculture.
Environmental context
The plant discharges into tributaries of the Yangtze River, which flows through central China into the East China Sea. The Yangtze basin is ecologically significant, supporting numerous fish species and providing water for millions of people. The plant's operations help reduce nutrient and pollutant loads, protecting downstream water quality and aquatic habitats.
Frequently asked questions
The Hubei wastewater treatment plant is located in Macheng, a county-level city under Huanggang, Hubei Province, China. Its address is on Dongpu Second Road, in the Gulou Street area.
The plant serves a population of 180,000 people, making it a medium-to-large agglomeration in the context of Chinese wastewater infrastructure.
The treated effluent is discharged into local rivers that are part of the Yangtze River basin. The Yangtze River ultimately flows into the East China Sea.
The plant operates under China's national wastewater discharge standards, primarily GB 18918-2002, which sets limits for pollutants like COD, BOD, and nutrients. Plants of this scale are typically required to meet Class 1A or 1B standards depending on the receiving water body's sensitivity.
For a plant serving 180,000 people, secondary biological treatment is standard, often using processes like activated sludge, A2O, or oxidation ditches. Advanced treatment for nutrient removal may be required if discharging into sensitive water bodies.
