Shaanxi Wastewater Treatment Plant, Fengming Town, Shaanxi Province

The Shaanxi wastewater treatment plant is located in Fengming Town, Qishan County, within Shaanxi Province, China. It serves a population of approximately 92,000, classifying it as a medium-sized municipal facility. The plant is situated in an inland region, away from coastal areas, and its operations are integral to local water management. Under China's national wastewater discharge standards (GB 18918-2002), plants serving populations of this scale are typically required to achieve at least secondary treatment, with stricter nutrient removal standards in sensitive watersheds. Regulatory expectations for agglomerations of this size emphasize reliable treatment to protect receiving waters. The plant discharges into local waterways that eventually drain into the Wei River, a major tributary of the Yellow River. This downstream connection highlights the plant's role in safeguarding water quality within the Yellow River basin, which supports agriculture, industry, and ecosystems across northern China.

The plant's treated effluent flows into local streams that feed the Wei River, a key tributary of the Yellow River. The Yellow River basin is ecologically significant, supporting diverse aquatic life and providing water for millions of people. Downstream areas include agricultural regions and wetlands that rely on stable water quality. The plant's discharge must meet national standards to prevent eutrophication and protect downstream ecosystems.
