Overview
The Hebei wastewater treatment plant serves Shenzhou City in Hengshui, Hebei Province, China, with a population equivalent of 85,000. It operates under China's national wastewater discharge standards.
The Hebei wastewater treatment plant is located in Shenzhou City, part of Hengshui in Hebei Province, China. It serves a population equivalent of 85,000, placing it in the medium-to-large agglomeration category for Chinese municipal wastewater infrastructure. Under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), plants of this scale are typically required to meet Class 1A or 1B standards, which mandate biological treatment with nutrient removal. Regulatory expectations for this population tier include secondary treatment with advanced nutrient control. The plant discharges into local waterways that ultimately drain into the Hai River basin, which flows into 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. Proper treatment at this plant helps reduce nutrient and pollutant loads to the sensitive coastal environment of Bohai Bay.
Environmental context
The Hebei plant discharges into the Hai River basin, which flows through the North China Plain and empties into Bohai Bay in the Bohai Sea. This coastal region supports important fisheries and migratory bird habitats. Nutrient pollution from wastewater can contribute to eutrophication in the bay, making effective treatment critical for maintaining water quality and ecosystem health.
