Method for electrokinetic remediation of heavy metal copper polluted soil
The invention discloses a method for electrokinetic remediation of heavy metal copper polluted soil, wherein the method specifically comprises electrokinetic remediation and electroosmosis drainage consolidation; anodes for electrokinetic remediation and electroosmosis drainage consolidation are made of plates plated with ruthenium, iridium and titanium on the surfaces, and cathodes for electroosmosis drainage consolidation are made of pure titanium materials; an anode electrolyte solution of the electrokinetic remediation is sodium chloride or sodium nitrate, and an electrolyte solution of a cathode is citric acid; and a grouting solution for electroosmosis drainage consolidation is a calcium chloride solution and a sodium silicate solution. According to the method, electrokinetic remediation and electroosmosis drainage consolidation are combined, a whole set of operation of pollution remediation and mechanical strength remediation of heavy metal contaminated soil with high water content is achieved, the influence of development of cracks at the plate-soil junction in the electroosmosis consolidation process on the consolidation process is explored, the cracks are filled in a double-liquid grouting mode, the optimal grouting time is obtained through tests, and a certain reference effect is achieved on treatment and reinforcement of actual polluted sites.
本发明公开了一种电动修复重金属铜污染土的方法，具体包括电动修复和电渗排水固结，所述电动修复和所述电渗排水固结的阳极均采用表面镀钌铱钛板，阴极均采用纯钛材料；其中，所述电动修复的阳极电解液为氯化钠或者硝酸钠，阴极的电解液为柠檬酸；所述电渗排水固结的注浆溶液为氯化钙溶液和硅酸钠溶液。本发明将电动修复和电渗排水固结结合起来，实现了对高含水率的重金属污染土的污染修复和力学强度修复的一整套化操作，并且通过探究了电渗固结过程中板土交界处裂缝发育对固结过程的影响，采用双液注浆的形式来填补裂隙，通过试验得出了最佳的注浆时间，对实际的污染场地的治理和加固具有一定参考作用。
