Overview
The Shaanxi wastewater treatment plant serves Qian County in Shaanxi Province, China, with a population equivalent of 80,000. It operates under China's national wastewater discharge standards.
The Shaanxi wastewater treatment plant is located in Qian County (乾县), within the Moxi Township (漠西乡) of Shaanxi Province, China. The facility serves a population equivalent of approximately 80,000 people, placing it in the medium-to-large agglomeration category for Chinese municipal wastewater infrastructure. As a Chinese treatment plant, it operates under the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits for conventional pollutants, nutrients, and heavy metals. For plants serving populations of this scale, secondary biological treatment is typically required, with potential nutrient removal in sensitive watersheds. The plant discharges into local waterways that ultimately drain into the Wei River system, a major tributary of the Yellow River. This watershed supports agricultural irrigation and provides water for downstream communities. The plant's operation is critical for protecting water quality in this densely populated region of the Guanzhong Plain.
Environmental context
The plant's treated effluent flows into local streams that are part of the Wei River basin, which drains into the Yellow River (Huang He) approximately 200 kilometers downstream. The Wei River is a key water source for agriculture and industry in Shaanxi Province, and its water quality directly affects the ecological health of the Yellow River. The region experiences a semi-arid climate, making water reuse and pollution control particularly important for sustaining local ecosystems and downstream water users.
