Overview
Shandong wastewater treatment plant serves Wulian County, Rizhao, Shandong, China, with a population of 110,000. It operates under China's national wastewater standards.
The Shandong wastewater treatment plant is located in Wulian County, part of Rizhao City in Shandong Province, China. It serves a population of approximately 110,000, classifying it as a medium-to-large agglomeration under Chinese municipal wastewater management. Under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), plants of this scale are typically required to meet Class 1A or 1B standards, which include biological treatment and nutrient removal. Regulatory expectations for this population tier include secondary treatment with potential advanced nutrient control. The treated effluent is discharged into local waterways within the Shandong Peninsula drainage basin, which ultimately flows into the Yellow Sea. The plant plays a key role in protecting downstream aquatic ecosystems and supporting water quality in the region's densely populated and industrial areas.
Environmental context
The plant discharges into the Shandong Peninsula watershed, which drains into the Yellow Sea. This coastal region supports diverse marine life and is an important fishing ground. Proper treatment is essential to prevent eutrophication and protect downstream water quality in the Yellow Sea.
