Hebei Wastewater Treatment Plant, Yuanshi County, Hebei Province, China

The Hebei wastewater treatment plant is located in Yuanshi County, Shijiazhuang, Hebei Province, China. It serves a population of approximately 84,200 people, placing it in the medium agglomeration category. The plant is situated inland, more than 50 km from the coast, and its treated effluent likely discharges into local rivers that eventually flow into the Bohai Sea. Under China's national wastewater standards, plants serving populations over 50,000 are typically required to achieve secondary treatment or higher. It is expected to comply with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants and nutrients. The plant plays a key role in protecting local water bodies in the Hai River basin, which drains into the Bohai Sea. By treating wastewater from Yuanshi County, it helps reduce pollution loads and supports aquatic life in downstream rivers and coastal ecosystems.

The plant's treated wastewater likely discharges into tributaries of the Hai River system, which flows into the Bohai Sea. The Bohai Sea is a semi-enclosed water body that supports diverse marine life and is important for fisheries. The plant's operation helps mitigate nutrient and pollutant inputs, protecting downstream water quality and aquatic habitats.
