Overview
Zhejiang wastewater treatment plant serves Lanxi City, Zhejiang Province, China, with a population of 193,000. It discharges treated water into local waterways within the Qiantang River basin.
The Zhejiang wastewater treatment plant is located in Lanxi City, within Jinhua City, Zhejiang Province, China. It serves a population of approximately 193,000, classifying it as a large agglomeration under Chinese wastewater management standards. The plant is situated in the Qiantang River basin, which drains into the East China Sea. As a large-scale facility, the plant is expected to meet secondary or advanced treatment standards under China's national discharge regulations (GB 18918-2002). Plants of this scale typically employ biological treatment with nutrient removal to protect downstream water quality. The plant's design and operation are subject to local environmental protection bureau oversight. The plant's treated effluent ultimately reaches the Qiantang River, which flows into Hangzhou Bay and the East China Sea. This water body supports diverse aquatic life and is an important ecological corridor for migratory fish species. The plant plays a key role in reducing pollutant loads to the river, helping to maintain water quality for downstream communities and ecosystems.
