Abstract:

In order to study the remedation technology of eutrophic artificial lake, an integrated restoration technique consisted of aquatic vegetation near lakesides, Effective Microorganisms (EM) , fingerlings and intermittent aeration system was constructed in Guilin City, Guangxi of China. The results indicated that the removal rates of Chemical Oxygen Demand (COD),total nitrogen (TN),total phosphorus (TP),suspended substance (SS) and turbidity achieved by this kind of technique were 63.14%~77.10%,54.18%~60.54%,85.76%~87.98%,82.36%,79.28% respectively, and the coverage ratio of duckweed decreases from 90% to 10%. Compared with conventional wastewater treatment systems, the integrated restoration technique do not cause secondary pollution, and has an obvious effect, especially it can maintain good water quality for a long time.
