Overview
Heilongjiang wastewater treatment plant serves Ranghulu District, Daqing, Heilongjiang, China. It handles a population of 169,000 and operates under China's national wastewater standards.
The Heilongjiang wastewater treatment plant is located in Ranghulu District, Daqing, Heilongjiang Province, China. It serves a population of approximately 169,000 people, making it a medium-to-large agglomeration in the region. The plant is situated in an inland area, far from the coast, and its operations are part of the municipal infrastructure for Daqing, a major industrial city known for oil production. As a Chinese wastewater facility, it operates under the national discharge standards set by the Ministry of Ecology and Environment, which mandate secondary treatment for urban wastewater. For plants serving over 100,000 people, advanced treatment may be required to meet stricter effluent limits, especially in sensitive watersheds. It is expected to comply with the relevant Chinese regulations for its scale. The treated effluent is likely discharged into a local water body that eventually flows into the Songhua River basin, a major tributary of the Amur River (Heilongjiang). The Songhua River supports diverse aquatic life and is an important water resource for northeastern China. The plant's operations contribute to protecting downstream water quality and the ecological health of the basin.
Environmental context
The plant discharges into a local watercourse that drains into the Songhua River, which flows northeast to join the Amur River (Heilongjiang) at the border with Russia. The Amur River ultimately empties into the Sea of Okhotsk. The Songhua River basin supports diverse aquatic ecosystems, including fish species such as sturgeon and salmon, and is an important migratory corridor for birds. Protecting water quality in this basin is critical for both ecological integrity and human use, including drinking water and agriculture.

The plant serves approximately 169,000 people in the Ranghulu District of Daqing.
The treated effluent is discharged into a local water body that flows into the Songhua River, a major tributary of the Amur River (Heilongjiang).
The plant operates under China's national wastewater discharge standards set by the Ministry of Ecology and Environment, which require secondary treatment for urban wastewater and may mandate advanced treatment for large agglomerations in sensitive areas.
For plants serving over 100,000 people, China's standards typically require secondary treatment as a minimum, with advanced treatment (tertiary) often needed to meet stricter effluent limits, especially in basins like the Songhua River that are ecologically important.
