Overview
Heilongjiang wastewater treatment plant serves Honggang District, Daqing, Heilongjiang, China, with a population of 137,000. It is located inland, discharging into local waterways.
The Heilongjiang wastewater treatment plant is located in Honggang District, Daqing, Heilongjiang Province, China. It serves a population of approximately 137,000 people, classifying it as a medium-to-large agglomeration under Chinese wastewater management standards. The plant is situated inland, away from coastal areas, and its operations are part of the municipal infrastructure for Daqing, a major industrial city known for oil production. Under China's national wastewater discharge standards (GB 18918-2002), plants serving populations over 100,000 are typically required to meet Class 1-A or 1-B effluent limits, which mandate advanced treatment including nutrient removal. The plant is expected to comply with these regulations to protect receiving water bodies. The population served suggests a substantial treatment capacity. The plant discharges treated effluent into local rivers that eventually flow into the Songhua River basin, a major water system in Northeast China. The Songhua River drains into the Amur River (Heilongjiang) and ultimately reaches the Sea of Okhotsk. The plant plays a key role in maintaining water quality in this industrial region, supporting aquatic life and downstream communities.
Environmental context
The plant discharges into local waterways within the Songhua River basin, which flows into the Amur River (Heilongjiang) and then to the Sea of Okhotsk. This watershed supports diverse aquatic ecosystems and is important for fisheries and agriculture. The region's cold climate and industrial activity (oil extraction) pose additional challenges for wastewater treatment and environmental protection.
