Overview
Heilongjiang wastewater treatment plant serves Daqing City, Heilongjiang, China, with a population equivalent of 200,000. The facility operates under China's national wastewater discharge standards.
The Heilongjiang wastewater treatment plant is located in Daqing City, Heilongjiang Province, China, serving a population of approximately 200,000. Situated in the industrial heart of the province, the plant is a key component of the region's municipal wastewater infrastructure. As a large agglomeration serving over 150,000 people, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates secondary treatment with nutrient removal for sensitive water bodies. The facility's treatment processes are designed to comply with these national standards, ensuring effluent quality protects downstream environments. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Songhua River basin. The Songhua River flows northeast into the Amur River (Heilongjiang) and eventually reaches the Sea of Okhotsk. The plant's operations are critical for protecting the ecological health of the Songhua River, which supports diverse aquatic life and provides water for agriculture and industry.
Environmental context
The plant discharges into the Songhua River basin, a major tributary of the Amur River (Heilongjiang) that flows into the Sea of Okhotsk. The watershed supports diverse aquatic ecosystems, including migratory fish species. The region experiences cold winters, which can affect treatment efficiency and require robust operational management to maintain compliance.
