Overview
Zhejiang wastewater treatment plant serves 2,000 people in Dongyang, Zhejiang, China. It operates under national discharge standards for small agglomerations.
The Zhejiang wastewater treatment plant is located in Dongyang, Jinhua, Zhejiang Province, China, serving a population of approximately 2,000. As a small-scale facility, it is part of China's expanding wastewater infrastructure in the Yangtze River Delta region. Plants of this size in China typically employ secondary biological treatment to meet the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). Its population equivalent suggests a modest throughput. The plant discharges into local waterways that ultimately drain into the East China Sea. Its operation helps protect downstream aquatic ecosystems and supports water quality in the densely populated Zhejiang province.
Environmental context
The plant's treated effluent enters the local river network within the Qiantang River basin, which flows into Hangzhou Bay and the East China Sea. This coastal region supports diverse marine life and is ecologically sensitive due to urban and industrial pressures. Proper treatment is vital to prevent eutrophication and maintain water quality in the downstream estuary.
Frequently asked questions
The plant is located on Yingshi Avenue in Dongyang, Jinhua, Zhejiang Province, China.
The plant serves approximately 2,000 people, classifying it as a small agglomeration.
Treated effluent is discharged into local rivers within the Qiantang River basin, ultimately reaching the East China Sea.
Small plants in China must comply with the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets limits on pollutants like COD, BOD, and nutrients.
For small agglomerations, secondary biological treatment (e.g., activated sludge or biofilm processes) is standard to meet discharge standards and protect receiving waters.
