Overview
Zhejiang wastewater treatment plant serves Lin'an District, Hangzhou, Zhejiang, China, with a population equivalent of 100,000. It discharges into local water bodies within the Qiantang River basin.
The Zhejiang wastewater treatment plant is located in Lin'an District, Hangzhou, Zhejiang Province, China, serving a population of approximately 100,000. The facility is situated in the Qingshan Lake Science and Technology City area, an urbanizing zone with industrial and residential development. As a plant serving a medium-to-large agglomeration in China, it operates under national wastewater discharge standards (GB 18918-2002) and local regulations. Chinese treatment plants of this scale typically employ secondary or advanced treatment processes to meet Class 1A or 1B standards, depending on the receiving water's sensitivity. Regulatory compliance requires effective nutrient removal for discharges into sensitive water bodies. The plant's treated effluent likely enters local waterways that drain into the Qiantang River, which flows into Hangzhou Bay and the East China Sea. This watershed supports diverse aquatic life and is important for regional water supply and fisheries. The plant plays a key role in protecting downstream water quality in a densely populated and economically active region.
Environmental context
The plant discharges into the Qiantang River basin, which flows through Hangzhou and into Hangzhou Bay, part of the East China Sea. This watershed supports important estuarine and coastal ecosystems, including migratory fish species and wetland habitats. The area is ecologically sensitive due to urban and industrial runoff, making effective wastewater treatment critical for maintaining water quality and biodiversity in the downstream environment.
