NOVELTY - Method for in situ repairing of deposits by electrocatalytic strengthening covering method involves (a) using the Peterson dredger to collect sediment surface samples and overlying water with relatively serious sediment pollution, (b) preserving the sediment surface samples collected in step (a) and the overlying water respectively, (c) stirring and mixing the sediment surface sample and the overlying water in step (b), and (d) treating the mixture obtained in step (c) by using the device for in-situ repairing deposits by electrocatalytic enhanced covering method. USE - Method for in-situ repairing deposit by electro-catalysis reinforced covering method used in environment finishing equipment preparation and application field. Can be used in removing pollutant in the sediment and inhibiting the pollutant release diffusion. ADVANTAGE - The method can directly convert the soluble organic matter into carbon dioxide, nitrogen dioxide and inorganic ions, so as to realize the technical effect of removing pollutant in the sediment and inhibiting the pollutant release diffusion. It can improve only the electrolytic device, and through the continuous movement of the device to realize large scale bottom mud repairing engineering. It is simple, convenient operation, strong mobility, and can be used for repairing the polluted bottom mud of large area, and removing multiple pollutants.
