Overview
The Hebei wastewater treatment plant serves the city of Zhangjiakou in Hebei Province, China, with a population equivalent of 65,000. It operates under China's national wastewater discharge standards.
The Hebei wastewater treatment plant is located in Zhuolu County, part of Zhangjiakou City in Hebei Province, China. The facility serves a population equivalent of 65,000, placing it in the medium-sized agglomeration category for Chinese municipal wastewater infrastructure. Under China's national wastewater treatment regulations, plants serving populations of this scale are typically required to meet Class 1-A or Class 1-B discharge standards under the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). These standards mandate secondary biological treatment with nutrient removal in sensitive watersheds. The plant's treated effluent is discharged into local waterways that ultimately drain into the Hai River basin, which flows into the Bohai Sea. The Hai River system supports agricultural irrigation and industrial water use in the region, making proper treatment essential for protecting downstream water quality and aquatic ecosystems.
Environmental context
The plant discharges into the Hai River basin, which flows through Hebei Province and Tianjin before emptying into the Bohai Sea. The Bohai Sea is a semi-enclosed marginal sea that supports diverse marine life and is an important fishing ground. The watershed faces challenges from industrial and agricultural runoff, making effective wastewater treatment critical for reducing nutrient loads and protecting coastal water quality.
