Overview
Heilongjiang wastewater treatment plant serves Youyi Township in Qiqihar, Heilongjiang, China. It treats wastewater from a population of approximately 66,700 under China's national discharge standards.
The Heilongjiang wastewater treatment plant is located in Youyi Township, part of Fuyu County in Qiqihar City, Heilongjiang Province, China. The facility serves a population of around 66,700, placing it in the medium agglomeration category for Chinese municipal wastewater infrastructure. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), set effluent quality requirements based on the receiving water body's sensitivity. Plants of this scale typically employ secondary biological treatment processes such as activated sludge or sequencing batch reactors to meet Class 1A or 1B standards, depending on local environmental needs. The plant's treated effluent is discharged into local waterways that ultimately flow into the Nen River, a major tributary of the Songhua River basin. The Songhua River drains into the Amur River (Heilongjiang) on the border with Russia, eventually reaching the Sea of Okhotsk. This watershed supports diverse aquatic life and provides water for agriculture and industry in the region.
Environmental context
The plant discharges into the Nen River system, part of the larger Songhua River basin. The Songhua River flows northeast into the Amur River, which empties into the Sea of Okhotsk. This watershed is ecologically significant, supporting fisheries and migratory bird habitats. The region experiences cold winters, which can affect treatment efficiency, and the river is used for irrigation and industrial water supply downstream.
