Overview
Ningxia Hui wastewater treatment plant serves Xiaoba Town in Ningxia, China, treating wastewater for approximately 79,700 residents. The plant discharges into local waterways within the Yellow River basin.
Ningxia Hui wastewater treatment plant is located in Xiaoba Town (小坝镇), part of Qingtongxia City in the Ningxia Hui Autonomous Region, China. The facility serves a population of around 79,700, placing it in the medium agglomeration category under Chinese wastewater regulations. China's wastewater treatment standards require secondary treatment for urban plants of this scale, with tertiary treatment increasingly mandated in sensitive watersheds. The plant operates under China's national discharge standards (GB 18918-2002), which set limits for pollutants like COD, BOD, and ammonia nitrogen. The facility likely employs conventional activated sludge or similar biological treatment to meet these standards. The plant discharges into local watercourses that ultimately drain into the Yellow River, one of China's most important river systems. The Yellow River basin supports extensive agriculture, industry, and ecosystems in northern China. Proper treatment at this plant helps protect downstream water quality in the Yellow River and its tributaries, which are critical for regional water security and ecological health.
Environmental context
The plant's treated effluent enters local streams that flow into the Yellow River, which traverses northern China before emptying into the Bohai Sea. The Yellow River basin is ecologically significant, supporting diverse aquatic life and providing water for irrigation and municipal use. Downstream areas include wetlands and agricultural regions that depend on good water quality. The plant's operation helps reduce nutrient and pollutant loads, mitigating eutrophication risks in receiving waters.
Frequently asked questions
Ningxia Hui wastewater treatment plant is located in Xiaoba Town (小坝镇), Qingtongxia City, Ningxia Hui Autonomous Region, China. The address is Huiyuan Street, Xiaoba Town.
The plant serves approximately 79,700 people, classifying it as a medium-sized municipal wastewater treatment facility under Chinese standards.
The treated effluent is discharged into local watercourses that flow into the Yellow River basin. The plant must comply with China's national discharge standards (GB 18918-2002) to protect downstream water quality.
The plant operates under China's national wastewater discharge standards (GB 18918-2002) and the Water Pollution Prevention and Control Law. For a plant of this scale, secondary treatment is typically required, with potential additional nutrient removal in sensitive areas.
For a medium-sized agglomeration in China, secondary biological treatment (e. g. , activated sludge) is standard. In environmentally sensitive watersheds like the Yellow River basin, tertiary treatment for nutrient removal may be required to meet stricter discharge limits.
