Overview
Hebei wastewater treatment plant serves Zhangjiakou City in Hebei Province, China, with a population equivalent of 202,000. The facility operates under China's national wastewater discharge standards.
The Hebei wastewater treatment plant is located in Yaojiafang Town, Qiaoxi District, Zhangjiakou City, Hebei Province, China. It serves a population equivalent of 202,000, classifying it as a large agglomeration under Chinese wastewater management regulations. The plant is situated inland, approximately 50 kilometers from the coast, and discharges into local water bodies. China's wastewater treatment standards, governed by the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), require secondary treatment as a baseline for plants of this scale. For sensitive areas, tertiary treatment may be mandated to control nutrients and protect receiving waters. The plant's operational context aligns with these national requirements, ensuring compliance with environmental protection goals. The treated effluent from the plant flows into the Yongding River system, part of the Hai River basin, which ultimately drains into the Bohai Sea. This watershed supports agricultural irrigation and urban water supply downstream. The plant plays a critical role in reducing pollutant loads to the river, protecting aquatic ecosystems and downstream water quality in a region facing water scarcity and industrial pressures.
Environmental context
The plant discharges into the Yongding River, a tributary of the Hai River basin, which flows into the Bohai Sea. This watershed is ecologically significant, supporting diverse aquatic life and providing water for agriculture and industry in northern China. The Bohai Sea is a semi-enclosed water body sensitive to nutrient pollution, making effective treatment essential to prevent eutrophication and protect marine biodiversity.
