Overview
Shandong wastewater treatment plant serves 279,300 people in Shizhong District, Zaozhuang, Shandong, China. It operates under national environmental regulations for large agglomerations.
The Shandong wastewater treatment plant is located in Shizhong District, Zaozhuang City, Shandong Province, China. It serves a population of 279,300, classifying it as a large agglomeration under Chinese wastewater management standards. The facility is situated in an inland area, approximately 50 km from the coast, and plays a key role in treating municipal wastewater for the region. As a large-scale plant, it is expected to meet secondary or advanced treatment standards as per China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). The plant's capacity and treatment processes are designed to handle the load from a population of this size, ensuring compliance with national effluent quality requirements. Regulatory oversight is provided by local environmental protection bureaus. The treated effluent is discharged into local waterways that ultimately drain into the Yellow Sea via the Shandong Peninsula's river systems. The plant's operation helps protect downstream aquatic ecosystems and supports water quality in the region, which is important for both ecological health and human use.
Environmental context
The plant discharges into rivers flowing through Shandong Province, part of the Huai River basin, which drains into the Yellow Sea. The downstream environment supports diverse aquatic life and is used for irrigation and fishing. Protecting water quality is critical to prevent eutrophication and maintain ecosystem services in this densely populated agricultural region.
