Overview
Zhejiang wastewater treatment plant serves Changxing County, Zhejiang, China, with a designed capacity of 1.00 and a population served of 42,000. It is located within 50 km of the coast.
The Zhejiang wastewater treatment plant is located in Hongqiao Town, Changxing County, Huzhou City, Zhejiang Province, China. It serves a population of 42,000 and has a designed capacity of 1.00, indicating it is a medium-scale facility for the region. As a plant in China, it operates under national wastewater discharge standards (GB 18918-2002) and local environmental regulations. For a facility serving approximately 42,000 people, secondary treatment with nutrient removal is typically required to meet effluent standards for surface water discharge. The plant's discharge likely enters local waterways that flow into Taihu Lake or the East China Sea, given its proximity to the coast. The surrounding region is ecologically sensitive due to intensive agriculture and urban development, making proper wastewater treatment critical for protecting downstream water quality and aquatic habitats.
Environmental context
The plant is situated within 50 km of the coast, suggesting its treated effluent may eventually reach the East China Sea via local rivers and canals. The region is part of the Yangtze River Delta, a densely populated and economically vital area where water quality management is crucial for sustaining fisheries, agriculture, and drinking water supplies. Downstream ecosystems support diverse aquatic life and migratory birds, requiring effective nutrient and pollutant removal.
