Overview
Tianjin wastewater treatment plant serves Jizhou District, Tianjin, China, with a population equivalent of 310,000. The facility operates under China's national wastewater discharge standards.
The Tianjin wastewater treatment plant is located in Yangxinzhuang Village, Jizhou District, Tianjin, China. It serves a population of approximately 310,000, classifying it as a large-scale municipal facility within the region. As a plant of this scale in China, it is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants, nutrients, and pathogens. The standard requires secondary treatment as a baseline, with more stringent limits for plants discharging into sensitive water bodies. The treated effluent is discharged into local waterways that ultimately drain into the Bohai Sea via the Hai River system. The receiving environment supports diverse aquatic life and is an important ecological corridor in the North China Plain. Proper treatment helps protect downstream water quality and marine ecosystems.
Environmental context
The plant discharges into the Hai River basin, which flows through Tianjin and empties into the Bohai Sea. The Bohai Sea is a semi-enclosed marginal sea with significant ecological importance, supporting fisheries and migratory bird populations. The watershed is heavily influenced by agricultural runoff and industrial activity, making effective wastewater treatment critical for maintaining water quality and ecosystem health.
