Overview
The Shandong wastewater treatment plant serves Linyi County, Dezhou, Shandong, China, with a population equivalent of 140,000. It operates under China's national wastewater discharge standards.
The Shandong wastewater treatment plant is located in Linyi County, Dezhou City, Shandong Province, China. It serves a population equivalent of 140,000, classifying it as a medium-to-large agglomeration under Chinese municipal wastewater management frameworks. As a plant of this scale, it is expected to meet the discharge standards set by China's Ministry of Ecology and Environment, which typically require secondary or advanced treatment depending on the receiving water body's sensitivity. Chinese regulations mandate that plants serving over 100,000 people achieve at least Class 1-A or 1-B standards under the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). The plant discharges treated effluent into local waterways that ultimately drain into the Yellow River basin, a major river system in northern China. The downstream environment supports agricultural irrigation and ecosystem services, making effective nutrient removal critical to prevent eutrophication in the river and its receiving Bohai Sea.
Environmental context
The plant's treated effluent flows into the Yellow River basin, which drains into the Bohai Sea. The Yellow River is a vital water source for agriculture and industry in northern China, and its lower reaches are ecologically sensitive to nutrient loading. The Bohai Sea is a semi-enclosed water body that experiences periodic algal blooms, underscoring the importance of stringent nutrient removal from wastewater discharges in the region.
Frequently asked questions
The plant is located at G340, Linyi County, Dezhou City, Shandong Province, China, with coordinates 37.21 N, 116.896 E.
The plant serves a population equivalent of 140,000, making it a medium-to-large agglomeration under Chinese wastewater classification.
The plant discharges into local waterways that are part of the Yellow River basin, which ultimately flows into the Bohai Sea.
The plant operates under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). Plants serving over 100,000 people typically must meet Class 1-A or 1-B standards, which require secondary treatment and nutrient removal.
For a plant of this scale in China, secondary treatment with biological nutrient removal is standard to meet Class 1-A or 1-B discharge limits, especially when discharging into sensitive water bodies like the Yellow River basin.
