Overview
Zhejiang wastewater treatment plant serves 240,000 people in Yueqing, Zhejiang, China. It is located within 50 km of the coast, discharging into the East China Sea watershed.
The Zhejiang wastewater treatment plant is located in Yueqing, a city under the administration of Wenzhou in Zhejiang Province, China. It serves a population of 240,000, classifying it as a large agglomeration under Chinese wastewater management standards. The plant is situated near the coast, within 50 km of the East China Sea. Plants of this scale in China are typically required to meet national discharge standards under the Environmental Protection Law and the Water Pollution Prevention and Control Law. These regulations mandate secondary or advanced treatment to protect receiving water bodies. The designed capacity is reported as 1.00 (likely in cubic meters per second or similar unit), indicating a substantial infrastructure investment. The plant's treated effluent ultimately reaches the East China Sea via local rivers and streams. The coastal environment supports diverse marine life and is important for fisheries and aquaculture. Proper treatment is essential to prevent eutrophication and protect coastal water quality in this densely populated region.
Environmental context
The plant discharges into the East China Sea watershed, likely via local rivers such as the Oujiang or Yongjiang. The coastal waters support diverse marine ecosystems, including fish spawning grounds and migratory bird habitats. Nutrient loading from untreated or inadequately treated wastewater could contribute to algal blooms and hypoxia in the nearshore environment.
