Hebei Wastewater Treatment Plant, Jinzhou, Shijiazhuang | China

The Hebei wastewater treatment plant is located in Jinzhou, a county-level city under the administration of Shijiazhuang, the capital of Hebei Province in northern China. The plant serves an estimated population of 75,000, placing it in the medium agglomeration category. As part of China's expanding wastewater infrastructure, the facility contributes to the treatment of municipal sewage in the region. China's wastewater treatment standards are governed by the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for various pollutants. For plants serving populations of this scale, secondary treatment with nutrient removal is typically required, especially in sensitive watersheds. The plant's operational details, including specific treatment processes and discharge volume, are not publicly available in this dataset. The treated effluent from the plant is discharged into local rivers that ultimately flow into the Bohai Sea via the Hai River system. The Hai River basin is a major water system in northern China, supporting agriculture, industry, and urban water supply. The region faces challenges related to water scarcity and pollution, making effective wastewater treatment critical for protecting downstream aquatic ecosystems and human health.

The plant discharges into the Hai River basin, which drains into the Bohai Sea. The Hai River system is heavily regulated and supports diverse aquatic life, though it has historically suffered from industrial and agricultural pollution. Effective treatment at this plant helps reduce nutrient and pollutant loads, protecting the ecological health of downstream rivers and the Bohai Sea coastal zone.
