Overview
Hebei wastewater treatment plant serves Tangshan, Hebei, China, with a population of 85,000. It operates under China's national wastewater discharge standards.
The Hebei wastewater treatment plant is located in Tangshan, Hebei Province, China, serving a population of approximately 85,000. The facility is situated in the Luan River basin, an important waterway in northern China. As a medium-sized agglomeration, the plant plays a key role in managing municipal wastewater from the古城街道 area of Luanzhou City. Under China's national wastewater discharge standards (GB 18918-2002), plants serving populations of this scale are typically required to meet Class 1-A or 1-B effluent limits, which include biological treatment and nutrient removal. The plant's treatment process and capacity are designed to comply with these regulations, ensuring treated water meets environmental standards before discharge. The treated effluent from the plant ultimately flows into the Luan River, which drains into the Bohai Sea. The Luan River supports diverse aquatic life and is an important water source for irrigation and industry in the region. Proper wastewater treatment here helps protect downstream ecosystems and coastal water quality in the Bohai Sea.
Environmental context
The plant discharges into the Luan River system, which flows through Hebei Province and empties into the Bohai Sea. The Luan River basin supports agricultural irrigation and provides habitat for freshwater fish species. Downstream, the Bohai Sea is a semi-enclosed marginal sea with significant ecological and economic importance, including fisheries and shipping. Effective wastewater treatment is critical to prevent eutrophication and protect marine biodiversity in this sensitive coastal environment.
