Beijing Wastewater Treatment Plant, Tongzhou District, Beijing, China

The Beijing wastewater treatment plant is situated in Yulinzhuang Village, Tongzhou District, Beijing, China. It serves a population of about 30,000, classifying it as a small to medium agglomeration under typical population tiers. The plant is part of Beijing's extensive municipal wastewater infrastructure, which is regulated under China's national water pollution control laws. As a plant serving a population of 30,000, it is expected to provide at least secondary treatment under Chinese regulations, which align with international standards for urban wastewater treatment. The plant operates within a framework that mandates effective treatment to protect water quality. The treated effluent is discharged into local rivers that flow through the North China Plain, eventually reaching the Bohai Sea. This region is ecologically significant, supporting diverse aquatic life and agricultural irrigation. The plant plays a crucial role in reducing pollution loads to downstream water bodies, contributing to the health of the Hai River basin ecosystem.

The plant discharges into the local river network within the Hai River basin, which flows through the North China Plain and ultimately into the Bohai Sea. This watershed supports intensive agriculture and urban areas, making pollution control critical. The downstream environment includes important wetlands and fisheries that depend on good water quality.
