Overview
Heilongjiang wastewater treatment plant serves 420,000 people in Longfeng District, Daqing, Heilongjiang, China. It operates under China's national wastewater standards for large agglomerations.
The Heilongjiang wastewater treatment plant is located in Longfeng District, Daqing, Heilongjiang Province, China. It serves a population of 420,000, classifying it as a large agglomeration under Chinese wastewater regulations. The plant is situated in the industrial city of Daqing, known for its petroleum industry. As a large-scale facility, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which requires secondary treatment as a minimum, with tertiary treatment in sensitive areas. Facilities of this scale typically employ biological treatment processes such as activated sludge or A2O. The plant discharges treated effluent into local water bodies that eventually drain into the Songhua River basin, a major tributary of the Amur River. The Songhua River supports diverse aquatic life and provides water for agriculture and industry downstream. Proper treatment is critical to prevent eutrophication and protect the river's ecological health.
Environmental context
The plant's treated effluent flows into 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 northeastern China, supporting agriculture, industry, and aquatic ecosystems. The region experiences cold winters, which can affect treatment efficiency, and the river is subject to seasonal ice cover. Protecting water quality in this basin is essential for downstream communities and biodiversity.
