Overview
Hebei wastewater treatment plant serves Yutian County in Tangshan, Hebei, China, with a population equivalent of 120,000. It operates under China's national wastewater standards.
The Hebei wastewater treatment plant is located in Yutian County, Tangshan City, Hebei Province, China. It serves a population of approximately 120,000 people, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. The plant is expected to comply with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). This standard mandates secondary treatment as a baseline, with stricter requirements for plants discharging into sensitive water bodies. For a facility serving 120,000 people, advanced treatment (tertiary) is often required to meet Class 1A or 1B effluent limits, particularly in environmentally sensitive areas. The plant discharges into local waterways that ultimately drain into the Bohai Sea via the Luan River system. The Bohai Sea is a semi-enclosed marginal sea with significant ecological importance, supporting fisheries and marine biodiversity. Effective treatment at this plant helps reduce nutrient and pollutant loads, protecting downstream aquatic ecosystems and coastal water quality.
Environmental context
The plant's treated effluent flows into the Luan River basin, which drains into the Bohai Sea. The Bohai Sea is a critical marine environment supporting diverse species and commercial fisheries. Nutrient pollution from upstream sources can contribute to eutrophication and harmful algal blooms in coastal waters. The plant's performance is therefore important for maintaining the ecological health of the Luan River estuary and the broader Bohai Sea ecosystem.
