Overview
Shandong wastewater treatment plant serves Yutai County in Shandong, China, with a population equivalent of 90,000. The facility discharges into local waterways under China's national wastewater standards.
The Shandong wastewater treatment plant is located in Yutai County, Jining City, Shandong Province, China. It serves a population equivalent of 90,000, classifying it as a medium-to-large agglomeration under Chinese municipal wastewater management. The plant is situated in the滨湖街道 area, near the shores of Weishan Lake, the largest freshwater lake in northern China. As a facility serving approximately 90,000 people, it falls under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates secondary treatment as a baseline and tertiary treatment for plants discharging into sensitive water bodies. Given the proximity to Weishan Lake, a key ecological and drinking water source, the plant likely operates under stricter discharge limits to protect water quality. The treated effluent from this plant ultimately flows into Weishan Lake, which drains into the Huai River system and eventually reaches the Yellow Sea. Weishan Lake supports diverse aquatic life and serves as a critical water source for the region. The plant's operation is vital for maintaining the ecological health of this important freshwater ecosystem and downstream environments.
Environmental context
The plant discharges into the Weishan Lake basin, which is part of the larger Huai River watershed. Weishan Lake is a major freshwater lake in northern China, supporting fisheries, irrigation, and drinking water supplies. The lake's ecological health is sensitive to nutrient loading, making effective wastewater treatment essential to prevent eutrophication. Downstream, the Huai River flows into the Yellow Sea, impacting coastal water quality.
Frequently asked questions
The Shandong wastewater treatment plant is located in Yutai County, Jining City, Shandong Province, China, near Weishan Lake.
The plant serves a population equivalent of 90,000 people.
The treated effluent from the Shandong WWTP is discharged into local waterways that flow into Weishan Lake, part of the Huai River basin, ultimately reaching the Yellow Sea.
The plant operates under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits based on the receiving water body's sensitivity.
For a plant of this scale in China, secondary treatment is the baseline requirement. If discharging into a sensitive water body like Weishan Lake, tertiary treatment with nutrient removal is typically required to meet stricter standards.
