Experimental Study on Electroosmotic Dehydration and Heavy Metal Removal of River Sediment
In view of the influence of river sediment on the environment, the electroosmotic treatment test of river sediment was carried out by using the mixture solution of biosurfactant sophora locust and citric acid, and the best flocculant obtained from construction waste mud test. Water yield, current density, water content distribution, allowable bearing capacity and heavy metal content in river sediment after the test were used as evaluation indexes to comprehensively evaluate the test effect of electroosmosis. The results showed that the dewatering effect of river sediment was obvious, and the flocculant could significantly improve the dehydration efficiency. In terms of heavy metal removal, the removal content of heavy metals in different regions was different, among which the removal rate of anode heavy metal was the highest.
