Nei Mongol, Qiaodong Village | China Wastewater

Overview

Nei Mongol wastewater treatment plant serves Qiaodong Village in Inner Mongolia, China, with a population equivalent of 80,000. It operates under China's national wastewater discharge standards.

The Nei Mongol wastewater treatment plant is located in Qiaodong Village, part of the Wengniute Banner area in Chifeng City, Inner Mongolia Autonomous Region, China. The facility serves a population equivalent of approximately 80,000 people, placing it in the medium-to-large agglomeration category for the region. As a municipal wastewater treatment plant in China, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). This regulatory framework sets effluent limits for conventional pollutants, nutrients, and priority substances, with stricter requirements for plants discharging into sensitive water bodies. Facilities of this scale typically employ biological treatment processes such as activated sludge or sequencing batch reactors to meet the required standards. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Liao River system. The Liao River flows through northeastern China and empties into the Bohai Sea. The receiving water body supports agricultural irrigation and local aquatic ecosystems, making proper treatment essential for protecting downstream water quality and ecological health.

Environmental context

The Nei Mongol plant discharges into the Liao River basin, which flows through Inner Mongolia and Liaoning Province before reaching the Bohai Sea. The watershed supports diverse aquatic life and is used for irrigation in the surrounding agricultural areas. The region experiences a semi-arid continental climate, making water resources particularly valuable and sensitive to pollution. Proper treatment helps maintain the ecological balance of the river system and protects downstream communities that rely on the water for various uses.

Frequently asked questions

The Nei Mongol wastewater treatment plant is located in Qiaodong Village, Wengniute Banner, Chifeng City, Inner Mongolia Autonomous Region, China. The address is Qiaodong Badui, Zicheng Street, Qiaodong Village.

The plant serves a population equivalent of approximately 80,000 people, classifying it as a medium-to-large agglomeration in the region.

The plant discharges into the Liao River basin, which flows through northeastern China and ultimately reaches the Bohai Sea. Proper treatment helps protect the water quality of the Liao River and its tributaries.

The plant operates under China's national standard GB 18918-2002, which sets discharge limits for pollutants from municipal wastewater treatment plants. Facilities serving populations over 50,000 are typically required to achieve secondary treatment with nutrient removal, especially if discharging into sensitive water bodies.

For a plant serving 80,000 people in China, typical treatment includes biological processes such as activated sludge or anaerobic-anoxic-oxic (A2O) systems to achieve secondary treatment standards. Many plants also incorporate tertiary treatment for nutrient removal to meet stricter local discharge limits.
