Overview
Shandong wastewater treatment plant serves Yanzhou District in Jining, Shandong, China, with a population equivalent of 98,500. The facility 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 equivalent of approximately 98,500, placing it in the medium-to-large agglomeration category under Chinese regulatory frameworks. The plant is situated in the urban area of Jining, a prefecture-level city in the southwestern part of Shandong. As a facility serving nearly 100,000 people, the plant is expected to meet the discharge standards set by China's Ministry of Ecology and Environment, which typically require secondary or advanced treatment for such scales. The plant's size suggests it likely employs biological treatment with nutrient removal to comply with local water quality goals. The plant discharges treated effluent into the local water system, which ultimately drains into the Nansi Lake basin, the largest freshwater lake in northern China. Nansi Lake is a critical water source for the region and part of the South-to-North Water Diversion Project. The plant's operations are therefore significant for protecting downstream water quality and supporting regional water resource management.
Environmental context
The plant's treated effluent flows into the Nansi Lake basin, which connects to the Huai River system and eventually the Yellow Sea. Nansi Lake is an ecologically sensitive area that supports diverse aquatic life and serves as a key water source for irrigation and drinking water in Shandong. The plant's discharge must meet stringent standards to prevent eutrophication and protect the lake's ecological health, particularly given its role in the South-to-North Water Diversion Project.
Frequently asked questions
The plant is located in Yanzhou District, Jining City, Shandong Province, China, at coordinates 35.583 N, 116.840 E.
The plant serves a population equivalent of 98,500 people, classifying it as a medium-to-large agglomeration under Chinese standards.
The plant discharges treated effluent into the local water system, which drains into the Nansi Lake basin and eventually the Huai River and Yellow Sea.
The plant operates under China's national wastewater discharge standards set by the Ministry of Ecology and Environment, which require secondary or advanced treatment for facilities serving over 50,000 people.
For a plant of this scale in China, typical treatment includes secondary biological processes with nutrient removal to meet Class 1A or 1B discharge standards, especially when discharging into sensitive water bodies like Nansi Lake.
