Overview
Hebei wastewater treatment plant serves Shahe City, Hebei Province, China, with a population equivalent of 140,000. The plant operates under China's national wastewater discharge standards.
The Hebei wastewater treatment plant is located in Shahe City, within the Xingtai prefecture of Hebei Province, China. It serves an estimated population of 140,000, classifying it as a medium-to-large agglomeration under Chinese municipal wastewater management frameworks. As a facility in China, the plant is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants, nutrients, and pathogens. For plants serving over 100,000 people, Class I-A standards are typically required, mandating advanced treatment including biological nutrient removal and disinfection. The plant discharges treated effluent into local waterways that ultimately drain into 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 in the North China Plain.
Environmental context
The plant's treated effluent enters the local river network within the Hai River basin, which flows eastward into the Bohai Sea. The Hai River system is heavily regulated due to water scarcity and pollution pressures, with the Bohai Sea receiving substantial nutrient loads from upstream sources. The plant's discharge contributes to the overall water quality in this ecologically sensitive coastal environment, where eutrophication and algal blooms are ongoing concerns.
