Hebei Wastewater Treatment Plant, Zhuozhou, Hebei Province, China

The Hebei wastewater treatment plant is located in Zhuozhou City, part of Baoding Prefecture in Hebei Province, China. It serves a population of approximately 350,000, classifying it as a large-scale municipal facility within the region's water management infrastructure. As a major treatment 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 based on receiving water sensitivity. For plants serving over 100,000 people, advanced treatment with nutrient removal is typically required to meet Class 1-A standards, especially in water-scarce northern China. The plant's treated effluent likely discharges into local waterways that flow through the Hai River basin, ultimately reaching the Bohai Sea. The Hai River system is critical for water supply and ecological health in the North China Plain, and the plant plays a key role in reducing pollution loads to this sensitive coastal environment.

The plant is situated in the Hai River basin, a major water system in northern China that drains into the Bohai Sea. The Hai River and its tributaries face significant water quality challenges due to industrial and agricultural runoff. The plant's discharge helps protect downstream aquatic ecosystems and supports water reuse efforts in this water-stressed region.
