Overview
Heilongjiang wastewater treatment plant serves 2,520,000 people in Harbin, Heilongjiang, China. It operates under China's national wastewater standards for large urban agglomerations.
The Heilongjiang wastewater treatment plant is located in the Daowai District of Harbin, the capital of Heilongjiang Province in northeastern China. It serves a population of approximately 2.52 million, classifying it as a large-scale municipal facility within the city's extensive wastewater infrastructure. As a major treatment plant in China, it is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets stringent effluent limits for large agglomerations. For plants serving over 1 million people, advanced treatment with nutrient removal is typically required to protect receiving waters, especially in sensitive basins. The plant discharges treated effluent into the Songhua River, a major tributary of the Amur River (Heilongjiang) system, which flows northeast into the Sea of Okhotsk. The Songhua River basin supports diverse aquatic life and provides drinking water for millions, making effective wastewater treatment critical for ecological and public health.
Environmental context
The plant's treated effluent enters the Songhua River, which flows through Harbin and joins the Amur River before reaching the Sea of Okhotsk. The Songhua River basin is ecologically significant, supporting fisheries and migratory bird populations. Downstream areas include wetlands that provide natural water purification and habitat for endangered species such as the Siberian tiger and Amur leopard.
