Overview
Nei Mongol wastewater treatment plant serves Huolinguole City in Inner Mongolia, China, with a population equivalent of 57,000. The facility operates under China's national wastewater discharge standards.
The Nei Mongol wastewater treatment plant is located in Huolinguole City, Inner Mongolia Autonomous Region, China. It serves a population of approximately 57,000, classifying it as a medium-sized municipal facility. The plant is situated in the Baorihujier subdistrict, within the Tongliao City administrative area. As a Chinese municipal wastewater treatment plant, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). This standard sets effluent limits for conventional pollutants, nutrients, and heavy metals. For a plant serving a population of this scale, secondary biological treatment with nutrient removal is typically required to meet Class 1A or 1B standards, depending on the receiving water's sensitivity. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Liao River basin. The Liao River flows through northeastern China and empties into the Bohai Sea. The region's semi-arid climate and seasonal water availability make proper wastewater treatment crucial for protecting downstream water quality and supporting local agriculture and ecosystems.
Environmental context
The Nei Mongol plant discharges into the Liao River basin, a major water system in northeastern China that flows into the Bohai Sea. The Liao River is ecologically important, supporting diverse aquatic life and providing water for irrigation and industry. Downstream, the river passes through densely populated areas before reaching the sea, making nutrient and pollutant removal critical to prevent eutrophication and protect coastal ecosystems.
