Overview
Hebei wastewater treatment plant serves the city of Wu'an in Handan, Hebei, China, with a population equivalent of 152,000. The plant operates under China's national wastewater discharge standards.
The Hebei wastewater treatment plant is located in Wu'an, a county-level city under the administration of Handan, in Hebei Province, China. Serving a population equivalent of 152,000, the facility is part of the municipal wastewater infrastructure for this urban area in the North China Plain. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), set effluent limits based on the receiving water body's sensitivity. For plants of this scale, secondary treatment with nutrient removal is typically required, especially if discharging into water bodies used for drinking water sources or that are prone to eutrophication. The plant's treated effluent likely discharges into a local river or stream within the Hai River basin, which ultimately flows into the Bohai Sea. The Hai River basin is a densely populated and industrialized region, making effective wastewater treatment critical for protecting downstream water quality and the marine environment of the Bohai Sea.
Environmental context
The Hebei plant is located inland in the Hai River basin, which drains into the Bohai Sea. The Hai River system is heavily influenced by agricultural runoff and industrial discharges, and the Bohai Sea is a semi-enclosed water body with limited water exchange, making it vulnerable to nutrient pollution. Effective treatment at this plant helps reduce the load of organic matter and nutrients entering the river and ultimately the sea, supporting the ecological health of the downstream aquatic environment.
Frequently asked questions
The Hebei wastewater treatment plant is located in Wu'an, a county-level city under the jurisdiction of Handan, in Hebei Province, China.
The plant serves a population equivalent of 152,000 people.
The treated effluent is likely discharged into a local watercourse within the Hai River basin, which ultimately flows into the Bohai Sea.
The plant operates under China's national wastewater discharge standards, specifically GB 18918-2002, which sets effluent limits for municipal wastewater treatment plants based on the sensitivity of the receiving water body.
For a plant of this scale in China, secondary biological treatment with nutrient removal is standard, especially if the receiving water body is sensitive to eutrophication. This typically involves activated sludge processes and may include advanced treatment for nitrogen and phosphorus removal.
