Overview
The Hebei wastewater treatment plant serves Cheng'an County in Handan, Hebei Province, China, with a population equivalent of 46,400. It operates under China's national wastewater discharge standards.
The Hebei wastewater treatment plant is located in Cheng'an County, Handan City, Hebei Province, China. It serves a population equivalent of 46,400, placing it in the medium-sized agglomeration category for Chinese municipal wastewater infrastructure. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), mandate secondary treatment as a baseline for plants of this scale. Typical facilities in this region employ biological treatment methods such as activated sludge or A2O processes to meet Class 1A or 1B discharge standards. The plant discharges treated effluent into local waterways that eventually drain into the Hai River basin, which flows into the Bohai Sea. The Hai River basin is a major water system in northern China, supporting agricultural irrigation and industrial water use, and is subject to stringent pollution control measures to protect downstream aquatic ecosystems and coastal waters.
Environmental context
The plant's treated effluent enters local tributaries of the Hai River system, which ultimately flows into the Bohai Sea. The Hai River basin is a densely populated and industrialized region, making effective wastewater treatment critical for controlling nutrient and pollutant loads. Downstream, the Bohai Sea is a semi-enclosed water body with limited water exchange, making it vulnerable to eutrophication and algal blooms from upstream discharges.
