Overview
Yunnan wastewater treatment plant serves Binchuan County in Yunnan province, China. It treats wastewater for approximately 38,000 people, supporting local water quality in the region.
The Yunnan wastewater treatment plant is located in Binchuan County, Dali Bai Autonomous Prefecture, Yunnan Province, China. It serves a population of around 38,000 residents in the area, contributing to municipal sanitation and environmental protection. As a plant serving a medium-sized agglomeration, it operates under China's national wastewater discharge standards, which require secondary treatment for urban wastewater. It is expected to meet the regulatory requirements for effluent quality before discharge. The plant's treated effluent is released into local water bodies that eventually drain into the broader Yangtze River basin or nearby lakes, depending on the specific hydrology. This helps protect downstream ecosystems and water resources in the region.
Environmental context
The plant discharges into local waterways that flow into the Jinsha River, a major tributary of the Yangtze River. The surrounding area features mountainous terrain and agricultural land, with the receiving waters supporting aquatic life and irrigation. Proper treatment is essential to prevent nutrient pollution and maintain water quality in this ecologically sensitive region.
