The Zhejiang wastewater treatment plant is situated in Longwan District, Wenzhou, within Zhejiang Province, China. It serves a population equivalent of 120,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management standards. The plant's designed capacity is recorded as 1. China's wastewater treatment regulations, governed by the Water Pollution Prevention and Control Law and national discharge standards (GB 18918-2002), require secondary treatment as a baseline for urban plants. For agglomerations of this scale, advanced treatment is often mandated in sensitive areas. Typical configurations for similar facilities include activated sludge processes with nutrient removal. The plant's location within 50 km of the coast means its treated effluent ultimately reaches the East China Sea, a major marine ecosystem. The receiving water body is likely a local river or canal that drains into the sea. This coastal proximity underscores the importance of effective nutrient and pollutant removal to protect marine water quality and coastal habitats.
Environmental context
The plant discharges into a local waterway that flows into the East China Sea, a semi-enclosed marginal sea supporting diverse marine life and important fisheries. The coastal region of Zhejiang is ecologically sensitive, with tidal flats and estuaries that serve as nurseries for fish and migratory bird habitats. Effective wastewater treatment is critical to prevent eutrophication and protect downstream marine ecosystems.
Frequently asked questions
The plant is located in Longwan District, Wenzhou, Zhejiang Province, China, near the coast of the East China Sea.
The plant serves a population equivalent of 120,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management standards.
The plant discharges treated effluent into a local waterway that ultimately flows into the East China Sea, given its location within 50 km of the coast.
The plant operates under China's Water Pollution Prevention and Control Law and national discharge standard GB 18918-2002, which sets limits for pollutants like COD, BOD, and nutrients.
For agglomerations of this scale, secondary treatment with activated sludge is standard, and advanced treatment (e. g. , nutrient removal) is often required in environmentally sensitive coastal areas.
