Overview
Heilongjiang wastewater treatment plant serves approximately 700,000 people in Yangming District, Mudanjiang, Heilongjiang, China. It operates under China's national wastewater standards for large agglomerations.
The Heilongjiang wastewater treatment plant is located in Yangming District, Mudanjiang City, Heilongjiang Province, China. It serves a population of approximately 700,000, classifying it as a large-scale municipal facility within the region's urban infrastructure. As a major treatment plant in Heilongjiang, it is expected to comply with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for plants serving over 100,000 people. The plant's scale suggests it likely employs biological treatment processes such as activated sludge or A2O to meet these standards. The treated effluent from the plant is discharged into local waterways that ultimately flow into the Songhua River basin, a major tributary of the Amur River system. This river network supports diverse aquatic life and provides water for agriculture and industry downstream, making effective treatment critical for regional water quality.
Environmental context
The plant discharges into the Songhua River basin, which flows northeast into the Amur River and eventually the Sea of Okhotsk. The watershed supports important fisheries and agricultural irrigation. Effective nutrient removal is essential to prevent eutrophication in downstream lakes and reservoirs.
