Overview
The Hebei wastewater treatment plant serves Hengshui City in Hebei Province, China, with a population equivalent of 360,000. It operates under China's national wastewater discharge standards.
The Hebei wastewater treatment plant is located in Hengshui City, Hebei Province, China, serving a population equivalent of 360,000. The plant is situated in the urban area of Taocheng District, within the larger Hengshui metropolitan region. As a major municipal facility, it plays a key role in managing the city's domestic and industrial wastewater. Under China's national wastewater treatment regulations, plants serving populations over 100,000 are typically required to achieve at least secondary treatment with nutrient removal, in line with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). The plant's treatment process and capacity are designed to meet these standards, ensuring compliance with local environmental protection requirements. The treated effluent is discharged into the local water system, which ultimately drains into the Hai River basin. The Hai River system flows into the Bohai Sea, a semi-enclosed marginal sea of the Pacific Ocean. The plant's operations help protect downstream aquatic ecosystems and reduce pollution loads entering the Bohai Sea, supporting regional water quality goals.
Environmental context
The plant discharges into the Hai River basin, which flows through Hebei Province and Tianjin before reaching the Bohai Sea. The Bohai Sea is a semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution from upstream sources. The plant's treatment helps mitigate eutrophication risks in the downstream estuary and coastal waters, supporting biodiversity in the region's aquatic habitats.
