Overview
Heilongjiang wastewater treatment plant serves Zhaodong City in Suihua, Heilongjiang, China. It handles a population of 246,000 and operates under national wastewater regulations.
The Heilongjiang wastewater treatment plant is located in Zhaodong City, Suihua, Heilongjiang Province, China. It serves a population of approximately 246,000 people, making it a significant municipal facility in the region. As a large agglomeration, the plant is expected to meet China's national discharge standards, which typically require secondary treatment or better for such scales. The facility's design and operation align with the country's Water Pollution Prevention and Control Action Plan, which mandates stringent effluent limits for major urban centers. The plant discharges treated wastewater into local waterways that ultimately drain into the Songhua River basin, a major tributary of the Amur River. This river system supports diverse aquatic life and provides water for agriculture and industry downstream. Proper treatment is critical to protect water quality and ecological health in the basin.
Environmental context
The plant's treated effluent enters the Songhua River basin, which flows northeast into the Amur River and eventually reaches the Sea of Okhotsk. The Songhua River is a vital water source for northeastern China, supporting fisheries, irrigation, and industrial use. Downstream ecosystems include wetlands and floodplains that provide habitat for migratory birds and fish species. Maintaining high treatment standards is essential to prevent nutrient pollution and protect biodiversity in this ecologically sensitive watershed.
