Overview
Heilongjiang wastewater treatment plant serves Yanshou County, Heilongjiang, China, with a population of 68,900. It operates under China's national wastewater standards.
The Heilongjiang wastewater treatment plant is located in Yanshou County, part of Harbin City in Heilongjiang Province, China. Serving a population of approximately 68,900, this facility is a key component of the region's municipal wastewater infrastructure, ensuring that domestic sewage is treated before discharge. China's wastewater treatment plants are regulated under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits based on the receiving water body's sensitivity. For a plant of this scale, secondary treatment with nutrient removal is typically required to meet Class 1A or 1B standards, especially in environmentally sensitive areas. The treated effluent from this plant is discharged into local water bodies that eventually flow into the Songhua River basin, a major tributary of the Amur River. The Songhua River supports diverse aquatic life and provides water for agriculture and industry downstream. Proper treatment at this facility helps protect water quality in the broader watershed.
Environmental context
The plant discharges into local waterways that drain into the Songhua River, a major tributary of the Amur River (Heilongjiang). The Songhua River basin supports diverse aquatic ecosystems and is important for regional agriculture and fisheries. Effective wastewater treatment is critical to prevent eutrophication and protect downstream water quality in this ecologically significant watershed.
