Overview
Henan wastewater treatment plant serves Huojia County in Xinxiang, Henan Province, China, with a population of 64,000. The facility operates under China's national wastewater discharge standards.
The Henan wastewater treatment plant is located in Huojia County, Xinxiang City, Henan Province, China. It serves a population of approximately 64,000 people, 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), require 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 treated effluent from the plant is discharged into local waterways that ultimately 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 ongoing pollution control efforts under China's Water Pollution Prevention and Control Action Plan.
Environmental context
The plant's discharge enters the local river network within the Hai River basin, which flows eastward through the North China Plain and empties into the Bohai Sea near Tianjin. This watershed supports intensive agriculture and urban centers, making water quality management critical. The Bohai Sea is a semi-enclosed marginal sea with limited water exchange, making it sensitive to nutrient pollution from upstream sources.
