Overview
Heilongjiang wastewater treatment plant serves 87,000 people in Harbin, Heilongjiang, China. It operates under national standards for municipal wastewater treatment.
The Heilongjiang wastewater treatment plant is located in Harbin, the capital of Heilongjiang province in northeastern China. It serves a population of 87,000, placing it in the medium agglomeration category for Chinese municipal wastewater infrastructure. As a Chinese municipal plant, it is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits based on receiving water sensitivity. For plants serving populations of this scale, secondary treatment with nutrient removal is typically required, especially when discharging into sensitive water bodies. The plant's treated effluent likely discharges into the Songhua River, a major tributary of the Amur River (Heilongjiang), which flows into the Sea of Okhotsk. The Songhua River supports diverse aquatic life and is an important water resource for the region, making proper treatment essential for downstream ecological health.
Environmental context
The plant is situated in the Songhua River basin, which drains into the Amur River and ultimately the Sea of Okhotsk. The Songhua River is a vital water source for Harbin and supports a range of fish species and migratory birds. Effective wastewater treatment is critical to prevent eutrophication and protect the river's ecological integrity, particularly given the cold climate which can slow natural biodegradation.
