Overview
The Hebei wastewater treatment plant serves Yingziyingzi Town in Chengde, Hebei Province, China, with a population equivalent of 69,000. It discharges into the Luan River system, which flows into the Bohai Sea.
The Hebei wastewater treatment plant is located in Yingziyingzi Town, Yingshouyingzi Mining District, Chengde, Hebei Province, China. It serves a population of approximately 69,000 people, classifying it as a medium-sized agglomeration under Chinese wastewater management standards. The plant is situated in a region characterized by mountainous terrain and a continental monsoon climate. As a facility serving a population of 69,000, the plant is expected to meet secondary treatment standards under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). This standard mandates pollutant removal to protect receiving water bodies. Typical plants of this scale employ biological treatment methods such as activated sludge. The treated effluent from the plant is discharged into the Luan River system, which flows eastward through Hebei Province and eventually into the Bohai Sea. The Luan River basin supports diverse aquatic life and provides water for agricultural and industrial use downstream. The plant plays a key role in protecting the local watershed from untreated sewage, particularly given the mining and industrial activities in the Yingshouyingzi area.
Environmental context
The Hebei plant discharges into the Luan River, a major watercourse in northern China that flows into the Bohai Sea. The Luan River basin supports a variety of fish species and provides irrigation water for surrounding farmland. Downstream, the river passes through urban and industrial areas before reaching the Bohai Sea, a semi-enclosed sea with significant ecological and economic importance. The plant's operation helps reduce nutrient and pollutant loads that could otherwise contribute to eutrophication and habitat degradation in the coastal zone.
