Overview
Guizhou wastewater treatment plant serves 250,000 people in Ximen Street, Kaili City, Guizhou Province, China. It operates under China's national wastewater discharge standards.
The Guizhou wastewater treatment plant is located in Ximen Street, Kaili City, within the Qiandongnan Miao and Dong Autonomous Prefecture of Guizhou Province, China. Serving a population of 250,000, this facility is a key component of the region's municipal wastewater infrastructure, addressing the needs of a medium-to-large urban agglomeration in southwestern China. As a Chinese wastewater treatment facility, the plant 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 pathogens. For plants serving populations of this scale, secondary treatment with nutrient removal is typically required, especially in sensitive watersheds. The facility's design and operation align with China's Water Pollution Prevention and Control Action Plan, which mandates improved treatment standards and stricter enforcement. The plant's treated effluent is discharged into local waterways that ultimately drain into the Yangtze River basin via the Wu River system. This region is ecologically significant, supporting diverse aquatic life and providing water for agriculture and domestic use downstream. The plant plays a crucial role in protecting water quality in the upper reaches of the Yangtze River, a vital water resource for millions of people.
Environmental context
The plant's discharge enters local streams that flow into the Wu River, a tributary of the Yangtze River. The Yangtze River basin is one of the world's most biodiverse freshwater ecosystems, supporting numerous fish species and providing critical habitat for migratory birds. Effective wastewater treatment is essential to prevent eutrophication and protect downstream water quality in this densely populated and ecologically sensitive region.
