Overview
Tianjin wastewater treatment plant serves Jinghai District, Tianjin, China, with a population equivalent of 100,000. The facility operates under China's national wastewater discharge standards.
The Tianjin wastewater treatment plant is located in Cuizhuangzi Village, Jinghai District, Tianjin, China. It serves a population equivalent of approximately 100,000, placing it in the medium-to-large agglomeration category for Chinese municipal wastewater infrastructure. The plant operates under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). For facilities serving populations of this scale, secondary biological treatment with nutrient removal is typically required, with effluent standards varying by receiving water body sensitivity. The plant discharges into the local water system within the Hai River basin, which ultimately flows into Bohai Bay. The Hai River basin is a major waterway in northern China, supporting agricultural, industrial, and urban water needs. Proper treatment at this plant helps protect downstream water quality and the ecological health of Bohai Bay.
Environmental context
The plant's treated effluent enters the Hai River basin, a critical water system in northern China that drains into Bohai Bay. The Hai River and its tributaries support diverse aquatic life and are used for irrigation and industrial water supply. Bohai Bay is a semi-enclosed sea area with significant ecological importance, hosting fisheries and migratory bird habitats. Effective wastewater treatment is essential to prevent eutrophication and protect marine biodiversity in the bay.
