Overview
The Hebei wastewater treatment plant serves Shijiazhuang, Hebei, China, with a population equivalent of 75,000. It operates under China's national wastewater discharge standards.
The Hebei wastewater treatment plant is located in Jinzhou, Shijiazhuang, Hebei Province, China, near the Huangshi Expressway. It serves a population of approximately 75,000 people, classifying it as a medium-sized municipal facility within the region's wastewater infrastructure. As a plant in China, it is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for conventional pollutants, nutrients, and heavy metals. For a facility of this scale, secondary treatment with nutrient removal is typically required to meet Class 1-A or 1-B standards, depending on the receiving water's sensitivity. The plant's treated effluent likely discharges into a local waterway within the Hai River basin, which flows into the Bohai Sea. The Hai River system is ecologically significant, supporting diverse aquatic life and providing water for agriculture and industry. Proper treatment is critical to prevent eutrophication and protect downstream coastal ecosystems.
Environmental context
The plant's treated wastewater likely enters a tributary of the Hai River, which flows through Hebei Province and ultimately discharges into the Bohai Sea. The Hai River basin is a heavily utilized water resource, facing challenges from industrial and agricultural runoff. The Bohai Sea is a semi-enclosed marginal sea with limited water exchange, making it sensitive to nutrient pollution that can cause algal blooms and hypoxia. Effective treatment at this plant helps mitigate these impacts.
