Shandong Wastewater Treatment Plant, Dezhou, Shandong Province

The Shandong wastewater treatment plant is located in Ningjin County, Dezhou, Shandong Province, China. It serves a population of approximately 90,000 people, placing it in the medium agglomeration category. The plant is situated inland, more than 50 kilometers from the coast, and its treated effluent is discharged into local water bodies that eventually flow into the Bohai Sea. The plant operates under China's national wastewater discharge standards, which mandate secondary treatment for urban wastewater treatment plants. For plants serving populations around 90,000, advanced treatment may be required if the receiving water body is designated as a sensitive area. The plant's design and operation are subject to local environmental protection bureau oversight. The plant's discharge contributes to the protection of local rivers and groundwater in the Hai River basin, which drains into the Bohai Sea. Proper treatment is essential for safeguarding downstream aquatic ecosystems and supporting regional water quality goals. The plant plays a key role in managing wastewater from Ningjin County and reducing pollution loads in the watershed.

The plant discharges into local waterways within the Hai River basin, which flows into the Bohai Sea. The region's water bodies support diverse aquatic life and are important for agriculture and fisheries. Effective treatment helps mitigate eutrophication and protects downstream ecological health in this densely populated area.
