Overview
Hebei wastewater treatment plant serves 70,000 people in Tangshan, Hebei, China. It operates under China's national wastewater standards for secondary treatment.
The Hebei wastewater treatment plant is located in Tangshan, Hebei Province, China, serving a population of approximately 70,000. The facility is situated in the San Tun Ying area of Qianxi County, within the broader Tangshan metropolitan region. As a plant serving a medium-sized agglomeration, it is expected to comply with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates secondary biological treatment and nutrient removal for facilities of this scale. Typical Chinese plants of this size employ activated sludge processes with anaerobic-anoxic-oxic (A2O) configurations for nitrogen and phosphorus removal. The plant discharges treated effluent into local water bodies that ultimately drain into the Bohai Sea via the Luan River system. The receiving environment supports diverse aquatic life and is an important coastal ecosystem. Proper treatment helps protect downstream water quality and marine habitats in the Bohai Sea.
Environmental context
The plant's treated effluent flows into tributaries of the Luan River, which discharges into the Bohai Sea, a semi-enclosed marginal sea of the Pacific Ocean. The Bohai Sea supports important fisheries and migratory bird habitats. Nutrient loading from wastewater can contribute to eutrophication in coastal waters, making effective treatment critical for maintaining ecological balance in this region.
