Overview
Tianjin wastewater treatment plant serves Dongli District, Tianjin, China, with a population equivalent of 1,110,000. The facility operates under China's national wastewater discharge standards.
The Tianjin wastewater treatment plant is located in Dongli District, Tianjin, China, serving a large urban agglomeration of approximately 1,110,000 people. As a major municipal facility, it plays a critical role in managing wastewater from the eastern part of the Tianjin metropolitan area. China's wastewater treatment regulations require secondary treatment as a baseline for large urban plants, with advanced treatment increasingly mandated for sensitive receiving waters. Plants serving over 1 million people are typically expected to achieve at least secondary treatment with nutrient removal to meet national discharge standards (GB 18918-2002). The plant's treated effluent likely discharges into the Hai River system, which flows through Tianjin and into the Bohai Sea. The Bohai Sea is a semi-enclosed water body with significant ecological importance, supporting fisheries and marine biodiversity. Effective treatment at this plant helps reduce nutrient and pollutant loads to the river and sea.
Environmental context
The plant's receiving water body is part of the Hai River basin, which drains into the Bohai Sea. The Bohai Sea is a semi-enclosed marginal sea with limited water exchange, making it sensitive to nutrient pollution and algal blooms. Protecting this marine environment requires stringent nutrient removal from upstream wastewater sources.
