Overview
Ningxia Hui wastewater treatment plant serves Pengyang County in Ningxia, China, with a population of 16,400. It operates under China's national wastewater standards for inland communities.
Ningxia Hui wastewater treatment plant is located in Pengyang County, part of the Ningxia Hui Autonomous Region in China. The facility serves a population of approximately 16,400 residents in the local community, contributing to the region's water management infrastructure. As a plant serving a medium-sized agglomeration, it is expected to comply with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits based on the receiving water body's sensitivity. For inland plants like this, secondary treatment with nutrient removal is typically required to protect local water quality. The plant discharges into the local watershed, which ultimately drains into the Yellow River basin. The surrounding area is characterized by a semi-arid climate, making water reuse and pollution control critical for sustaining agricultural and ecological needs downstream.
Environmental context
The plant's treated effluent enters local waterways that flow into the Ruhe River, a tributary of the Yellow River system. The Yellow River basin supports intensive agriculture and is ecologically sensitive due to water scarcity and pollution pressures. Proper treatment helps protect downstream aquatic habitats and water quality for irrigation and domestic use.
