Overview
Beijing wastewater treatment plant in Changping District serves 90,000 people. The facility operates under China's national wastewater standards for urban agglomerations.
The Beijing wastewater treatment plant is located in Goutou Village, Changping District, Beijing, China. It serves a population of 90,000, classifying it as a medium-sized municipal facility within the greater Beijing metropolitan area. As a Chinese wastewater treatment plant, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for plants of this scale. Typical plants serving similar populations employ activated sludge processes with biological nitrogen and phosphorus removal. The plant discharges treated effluent into local water bodies that ultimately flow into the Hai River system, which drains into the Bohai Sea. The facility plays a key role in protecting downstream aquatic ecosystems and supporting water quality in the densely populated Beijing region.
Environmental context
The plant's treated effluent enters the local drainage network within the Hai River basin, which flows through Tianjin and discharges into the Bohai Sea. The Bohai Sea is a semi-enclosed marginal sea with significant ecological importance, supporting fisheries and migratory bird populations. The plant's nutrient removal helps mitigate eutrophication risks in downstream waters.
