Overview
The Shandong wastewater treatment plant serves a population of 520,000 in Yanzhou District, Jining, Shandong, China. It operates under China's national wastewater discharge standards.
The Shandong wastewater treatment plant is located in Yanzhou District, Jining City, Shandong Province, China. It serves a population of approximately 520,000, classifying it as a large-scale municipal facility within the region's water infrastructure. As a major treatment plant in China, it is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants and nutrients. For plants of this scale, advanced treatment with nutrient removal is typically required to meet Class 1A standards, especially in sensitive watersheds. The plant's treated effluent is discharged into local waterways that ultimately drain into the Yellow Sea via the Huai River system. The downstream environment supports agricultural irrigation and aquatic ecosystems, making effective nutrient removal critical to prevent eutrophication in receiving waters.
Environmental context
The plant discharges into the local river network within the Huai River basin, which flows eastward to the Yellow Sea. This region is intensively farmed, and nutrient loading from wastewater can contribute to algal blooms in downstream lakes and coastal zones. Protecting water quality is essential for both ecological health and agricultural water reuse.
Frequently asked questions
