Integrated Application and Effect of Pollution Control Technology in the Jiushanwai River of Wenzhou City

A pollution control technology was applied to the Jiushanwai River of Wenzhou City. The pollution control technology included external water transfer, sediment eco-dredging, riparian retention, artificial aeration and the use of ecological floating bed （Island） technology. The Jiushanwai River environment was improved significantly after the treatment on black and smelly water. Water quality was improved from the inferior Class V to Class V or Class IV water. Water habitats and biodiversity were also improved to some extent. About 62.9% of inhabitants were satisfied with the Jiushanwai River treatment project and gave a merit mark of 60 marks or above.
