Overview
Hebei wastewater treatment plant serves Dingzhou, Hebei, China, with a population equivalent of 300,000. It operates under China's national wastewater discharge standards.
The Hebei wastewater treatment plant is located in Dingzhou, a city in Hebei Province, China. Serving a population of approximately 300,000, it is a medium-to-large agglomeration facility that plays a key role in managing municipal wastewater for the region. Under China's national wastewater discharge standards (GB 18918-2002), plants of this scale are typically required to meet Class 1-A or 1-B effluent limits, which include biological treatment and nutrient removal. It is expected to comply with these regulatory requirements. The plant's treated effluent is discharged into local waterways that ultimately drain into the Hai River basin, which flows into the Bohai Sea. This downstream environment supports diverse aquatic life and is important for regional water quality and ecosystem health.
Environmental context
The plant discharges into the Hai River basin, which flows through Hebei Province and eventually reaches the Bohai Sea. The Bohai Sea is a semi-enclosed marginal sea that supports fisheries and migratory bird habitats. Protecting water quality in this basin is critical for maintaining ecological balance and reducing nutrient pollution in coastal waters.
