Overview
Heilongjiang wastewater treatment plant serves 156,000 people in Xingfu Township, Heihe, Heilongjiang, China. It operates under China's national wastewater standards for large agglomerations.
The Heilongjiang wastewater treatment plant is located in Changfa Village, Xingfu Township, Aihui District, Heihe City, Heilongjiang Province, China. Serving a population of 156,000, it falls into the category of a large agglomeration under Chinese wastewater regulations, which require advanced treatment for such scales to protect water resources. As a plant serving over 150,000 people, it is expected to meet stringent discharge standards under China's Water Pollution Prevention and Control Law and the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). These regulations mandate secondary or tertiary treatment depending on the receiving water body's sensitivity, with nutrient removal often required for large plants. The plant discharges into local waterways that ultimately drain into the Heilong River (Amur River), which forms the border between China and Russia and flows into the Sea of Okhotsk. The river supports diverse aquatic life and is an important migratory corridor for fish species. The plant's operation is critical for maintaining water quality in this transboundary river system.
Environmental context
The plant's treated effluent enters local streams that feed into the Heilong River (Amur River), one of the world's longest rivers, which flows northeast into the Sea of Okhotsk. The river basin supports a rich ecosystem including salmonid fisheries and wetland habitats. As a large agglomeration, the plant must meet high treatment standards to prevent nutrient pollution and protect downstream aquatic biodiversity in this ecologically sensitive transboundary waterway.
