Overview
Zhejiang wastewater treatment plant serves 350,000 people in Binjiang District, Hangzhou, Zhejiang Province, China. It operates under national wastewater regulations for large agglomerations.
The Zhejiang wastewater treatment plant is located in Binjiang District, Hangzhou, within Zhejiang Province, China. It serves a population of approximately 350,000, classifying it as a large agglomeration under Chinese wastewater management standards. The facility is situated in a densely populated urban area along the Qiantang River basin. As a large-scale plant, it is expected to meet secondary or advanced treatment standards as per China's national discharge limits (GB 18918-2002). Facilities of this size typically employ biological treatment processes such as activated sludge or A2O to achieve required effluent quality. Regulatory oversight is provided by local environmental protection bureaus under the Ministry of Ecology and Environment. The plant discharges treated effluent into the Qiantang River, which flows into Hangzhou Bay and ultimately the East China Sea. This water body supports diverse aquatic life and is an important ecological corridor. The plant plays a critical role in protecting downstream water quality and public health in the Hangzhou metropolitan area.
Environmental context
The plant's treated effluent enters the Qiantang River, a major waterway in Zhejiang that flows through Hangzhou and into Hangzhou Bay, an estuary of the East China Sea. The river supports a variety of freshwater and brackish water species and is a key resource for irrigation and industrial use. Downstream, Hangzhou Bay is ecologically sensitive due to its role as a nursery for marine life and a stopover for migratory birds. Effective treatment at this plant helps mitigate nutrient loading and pollution in this dynamic coastal environment.
