Overview
Hebei wastewater treatment plant serves Suning County, Cangzhou, Hebei, China, with a population equivalent of 95,000. The facility operates under China's national wastewater discharge standards.
The Hebei wastewater treatment plant is located in Suning County, Cangzhou, Hebei Province, China. It serves a population equivalent of 95,000, placing it in the medium-to-large agglomeration category for Chinese municipal wastewater infrastructure. Under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), plants serving this population scale are typically required to achieve at least secondary treatment, with more stringent standards in sensitive watersheds. Regulatory compliance is enforced through provincial environmental protection bureaus. The plant discharges treated effluent into local water bodies that ultimately drain into the Hai River system, which flows into the Bohai Sea. The Hai River basin is a major industrial and agricultural region, making effective wastewater treatment critical for downstream water quality and marine ecosystem health.
Environmental context
The plant's treated effluent enters the Hai River basin, which drains into the Bohai Sea via the Hai River estuary. The Bohai Sea is a semi-enclosed marginal sea with limited water exchange, making it sensitive to nutrient loading from municipal and industrial discharges. The region supports important fisheries and migratory bird habitats, and excessive nutrient inputs can contribute to eutrophication and harmful algal blooms.
