Overview
Zhejiang wastewater treatment plant serves Beilun District, Ningbo, Zhejiang, China, with a designed capacity of 1.00 unit and a population served of 320,000. It is located within 50 km of the coast.
The Zhejiang wastewater treatment plant is located in Beilun District, Ningbo, Zhejiang Province, China. It serves a population of 320,000 and has a designed capacity of 1.00 unit, indicating it is a medium-to-large agglomeration under Chinese wastewater regulations. China's wastewater treatment standards are governed by the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits based on the receiving water body's sensitivity. For plants of this scale, secondary treatment with nutrient removal is typically required, especially in coastal areas to prevent eutrophication. The plant is situated within 50 km of the coast, and its treated effluent likely discharges into local rivers or directly into the East China Sea. The surrounding watershed includes the Yong River system, which flows into Hangzhou Bay and ultimately the East China Sea. This coastal region supports diverse marine life and is important for fisheries and aquaculture.
Environmental context
The plant's location near the coast means its effluent can impact the East China Sea, a semi-enclosed sea with significant ecological importance. The Yong River and its tributaries drain the area, carrying treated wastewater into Hangzhou Bay, which supports migratory fish and shellfish populations. Nutrient loading from wastewater can contribute to algal blooms, so effective treatment is critical for maintaining water quality in this sensitive coastal environment.
