The Heilongjiang wastewater treatment plant is located in Lamaodian Town, Ranghulu District, Daqing City, Heilongjiang Province, China. It serves a population of approximately 290,000, making it a medium-to-large agglomeration under Chinese wastewater classification. As a plant in China, it is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants and nutrients. For plants of this scale, secondary treatment with nutrient removal is typically required, especially in sensitive watersheds. The plant's treated effluent is discharged into local waterways that ultimately drain into the Songhua River basin, a major tributary of the Amur River. The region's cold climate and industrial activity in Daqing (oil and petrochemical) influence the treatment challenges and environmental management priorities.
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 diverse aquatic life and is an important migratory corridor for fish species. Downstream ecosystems include wetlands and floodplains that provide critical habitat and water purification services.
