Overview
Hebei wastewater treatment plant serves Sanhe City in Hebei Province, China, with a population equivalent of 104,000. The facility operates under China's national wastewater discharge standards.
The Hebei wastewater treatment plant is located in Sanhe City, Hebei Province, China, serving a population equivalent of 104,000. Situated in the Yanjiao High-Tech Industrial Development Zone, the plant supports a rapidly urbanizing area near Beijing. As a medium-to-large agglomeration, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for sensitive water bodies. Typical plants of this scale in China employ activated sludge processes with biological nutrient removal. The plant discharges treated effluent into local waterways that ultimately drain into the Hai River system, which flows into the Bohai Sea. The Hai River basin is ecologically significant, supporting diverse aquatic life and providing water for agriculture and industry. Proper treatment is critical to prevent eutrophication and protect downstream coastal ecosystems.
Environmental context
The plant's treated effluent enters the Hai River basin, which flows through Hebei Province and Tianjin before reaching the Bohai Sea. The Bohai Sea is a semi-enclosed marginal sea with limited water exchange, making it sensitive to nutrient pollution. The Hai River system supports important fisheries and migratory bird habitats, and excessive nutrient loads can lead to algal blooms and hypoxia. Effective wastewater treatment is essential to maintain water quality in this densely populated and industrialized region.
Frequently asked questions
The Hebei wastewater treatment plant is located in Sanhe City, Hebei Province, China, specifically in the Yanjiao High-Tech Industrial Development Zone along Zuodi Road.
The plant serves a population equivalent of 104,000, classifying it as a medium-to-large agglomeration under Chinese wastewater regulations.
Treated effluent from the plant is discharged into local waterways that are part of the Hai River basin, which ultimately flows into the Bohai Sea.
The plant must comply with China's GB 18918-2002 standard, which sets discharge limits for pollutants such as COD, BOD, ammonia, and phosphorus. Plants of this scale typically require secondary treatment with nutrient removal.
The Hai River basin drains into the Bohai Sea, a semi-enclosed sea vulnerable to eutrophication. Proper treatment at the Hebei plant helps protect downstream aquatic ecosystems and coastal water quality.
