Overview
Heilongjiang wastewater treatment plant serves Suiyang Town in Dongning, Mudanjiang, Heilongjiang, China. The plant supports a population of 67,000 and operates under China's national wastewater standards.
The Heilongjiang wastewater treatment plant is located in Suiyang Town, Dongning City, Mudanjiang Prefecture, Heilongjiang Province, China. It serves a population of approximately 67,000 people in this northeastern region. As a municipal facility in China, the plant is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). For agglomerations of this scale, secondary treatment with nutrient removal is typically required, especially in sensitive watersheds. Chinese regulations mandate compliance with effluent standards for COD, BOD, ammonia nitrogen, and total phosphorus. The plant discharges treated wastewater into the local water system, which ultimately drains into the Suifen River and then into the Sea of Japan. This watershed supports aquatic ecosystems and is important for regional water quality. The plant's operation helps protect downstream environments from untreated sewage pollution.
Environmental context
The plant's treated effluent flows into the Suifen River basin, which drains eastward into the Sea of Japan. This coastal watershed supports diverse aquatic life and is used for irrigation and fisheries. The region experiences cold winters, affecting treatment efficiency. Protecting this water body from nutrient pollution is critical for maintaining ecological balance in the downstream marine environment.
