Overview
The Hubei wastewater treatment plant serves Yunyang District, Shiyan, Hubei, China, with a population of 95,000. It operates under China's national wastewater standards.
The Hubei wastewater treatment plant is located in Yunyang District, Shiyan City, Hubei Province, China. It serves a population of approximately 95,000 people, placing it in the medium-to-large agglomeration category for Chinese municipal wastewater infrastructure. Under China's national wastewater discharge standards (GB 18918-2002), plants of this scale are typically required to achieve at least secondary treatment, with more stringent nutrient removal in sensitive watersheds. The regulatory framework ensures compliance with effluent limits for organic matter and suspended solids. The plant discharges into the local water system, which ultimately drains into the Han River, a major tributary of the Yangtze River. The Han River supports diverse aquatic life and provides water for agriculture and drinking downstream. Proper treatment is critical to protect water quality in this densely populated region.
Environmental context
The plant's treated effluent flows into local waterways that feed the Han River, a key tributary of the Yangtze River. The Han River basin supports extensive agriculture and fisheries, and its water quality is vital for downstream communities in Hubei and beyond. The region's subtropical climate and seasonal rainfall can affect dilution capacity, making consistent treatment important for ecological health.
Frequently asked questions
