Overview
Heilongjiang wastewater treatment plant serves Beilin District, Suihua, Heilongjiang, China, with a population of 285,000. It operates under China's national wastewater standards for urban agglomerations.
The Heilongjiang wastewater treatment plant is located in Beilin District, Suihua City, Heilongjiang Province, China. It serves an estimated population of 285,000, classifying it as a medium-to-large urban agglomeration under Chinese wastewater management frameworks. As a plant of this scale, it is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which mandates secondary treatment with nutrient removal for sensitive receiving waters. Typical configurations for similar facilities include activated sludge systems with biological nitrogen and phosphorus removal. The plant discharges treated effluent into the local watershed, which ultimately drains into the Songhua River basin. The Songhua River flows northeast through Heilongjiang and joins the Amur River (Heilongjiang) before reaching the Sea of Okhotsk. This river system supports diverse aquatic life and is important for regional agriculture and fisheries.
Environmental context
The plant's treated effluent enters the local water network that feeds into the Songhua River, a major tributary of the Amur River. The Songhua River basin is ecologically significant, supporting fish species such as Amur sturgeon and kaluga, and providing water for irrigation and industry. Downstream, the Amur River forms part of the border with Russia and discharges into the Sea of Okhotsk, a productive marine ecosystem. Protecting water quality in this basin is critical for both human use and biodiversity.
