Hebei Wastewater Treatment Plant, Xinglong County, Chengde, Hebei, China

The Hebei wastewater treatment plant is located in Xinglong County, Chengde City, within Hebei Province, China. It serves a population of approximately 68,100, classifying it as a medium-sized municipal facility. The plant is situated inland, away from coastal areas, and its operations are part of the regional water management infrastructure for the Luan River basin. Under China's national regulations, wastewater treatment plants serving populations over 50,000 are typically required to meet Grade 1-A discharge standards, which include biological nutrient removal. The plant is expected to comply with these standards to protect local water quality. Its population served suggests a capacity in the range of 10,000 to 20,000 cubic meters per day. The plant discharges treated effluent into a local watercourse that ultimately flows into the Luan River, a major river in Hebei Province that drains into the Bohai Sea. The Luan River supports diverse aquatic life and provides water for agricultural and industrial use downstream. Proper treatment at this plant helps reduce nutrient and pollutant loads, safeguarding the ecological health of the river and the marine environment of the Bohai Sea.

The treated effluent from the Hebei plant enters a tributary of the Luan River, which flows through Hebei Province before reaching the Bohai Sea. The Luan River basin is an important ecological corridor, supporting fish species and migratory birds. Downstream, the Bohai Sea is a semi-enclosed marine body that faces eutrophication risks from nutrient inputs. Effective wastewater treatment at this plant helps mitigate these impacts by reducing nitrogen and phosphorus loads.
