Overview
Beijing wastewater treatment plant serves Changping District, Beijing, China, with a population of 200,000. It operates under China's national wastewater discharge standards.
The Beijing wastewater treatment plant is located in Changping District, Beijing, China, serving a population of 200,000. It is part of the municipal wastewater infrastructure for the broader Beijing metropolitan area, one of the most populous urban regions in the world. The plant's location in the northern part of Beijing places it within the Hai River basin, which drains into the Bohai Sea. As a facility serving 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 plants of this scale. The regulatory framework in China requires compliance with effluent limits for COD, BOD, ammonia nitrogen, and total phosphorus, with stricter standards for plants discharging into sensitive water bodies. The treated effluent likely discharges into the Wenyu River or a tributary of the North Canal, which flows into the Hai River system and ultimately reaches the Bohai Sea. The Bohai Sea is a semi-enclosed marginal sea that supports fisheries and marine biodiversity but faces eutrophication pressures from upstream nutrient loads. The plant's performance is critical for protecting downstream water quality and the ecological health of the Bohai Sea.
Environmental context
The plant discharges into the Hai River basin, which flows through the North China Plain and empties into the Bohai Sea. The Bohai Sea is a semi-enclosed sea with limited water exchange, making it vulnerable to nutrient pollution and algal blooms. The plant's treated effluent contributes to the overall nutrient load entering the sea, affecting marine ecosystems and coastal fisheries. Effective treatment is essential to mitigate eutrophication risks in this sensitive marine environment.
Frequently asked questions
The plant is located in Changping District, Beijing, China, at the China Electronics Changping Science Park in Baifu Village.
The plant serves a population of 200,000 people in the Changping District of Beijing.
The treated effluent is discharged into the Hai River basin, which flows into the Bohai Sea. The plant must comply with China's national discharge standards to protect downstream water quality.
The plant operates under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for key pollutants. Plants serving over 100,000 people are typically required to achieve secondary treatment with nutrient removal.
For a plant of this scale in China, secondary treatment with biological nutrient removal is standard. This includes processes to reduce organic matter, suspended solids, nitrogen, and phosphorus to meet the national discharge standards.
