Overview
Heilongjiang wastewater treatment plant serves Jiagadaqi District in Heilongjiang, China, with a population of 163,000. It operates under China's national wastewater standards.
The Heilongjiang wastewater treatment plant is located in Jiagadaqi District, part of the Daxing'anling region in Heilongjiang Province, China. It serves a population of approximately 163,000, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. 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 various pollutants. For plants of this scale, secondary treatment with nutrient removal is typically required, especially if discharging into sensitive water bodies. It is expected to comply with national standards. The plant discharges into the local watershed, which ultimately drains into the Nen River, a major tributary of the Songhua River. The Songhua River flows through northeastern China before reaching the Amur River (Heilongjiang) and eventually the Sea of Okhotsk. This river system supports diverse aquatic life and is important for regional agriculture and industry.
Environmental context
The plant's treated effluent enters the local water system, which flows into the Nen River, a key tributary of the Songhua River. The Songhua River basin is ecologically significant, supporting fish species such as the Amur catfish and serving as a water source for millions. Downstream, the Amur River forms the border with Russia and empties into the Sea of Okhotsk, a productive marine ecosystem. The region experiences cold winters, which can affect treatment efficiency and require robust infrastructure.
