Hebei Wastewater Treatment Plant, Kuancheng Man Autonomous County, Hebei, China

The Hebei wastewater treatment plant is located in Kuancheng Man Autonomous County, part of Chengde City in Hebei Province, China. The facility serves a population of approximately 72,000 people, addressing the municipal wastewater needs of this county-level city. As a medium-sized agglomeration, the plant plays a key role in managing urban wastewater in the region. China's wastewater treatment standards are governed by national regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). For plants serving populations around 70,000, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water body's sensitivity. The plant's operational context aligns with these national requirements. The treated effluent from the plant is discharged into local waterways that ultimately flow into the Luan River system, which drains into the Bohai Sea. The plant's operation helps protect downstream aquatic ecosystems and supports water quality in the Luan River basin, an important water source for the region.

The Hebei plant discharges into the Luan River basin, which flows through Hebei Province and empties into the Bohai Sea. The Luan River supports diverse aquatic life and provides water for agriculture and industry. Protecting this watershed is critical for maintaining ecological balance and water quality in the downstream Bohai Sea coastal zone.
