| Abstract: | The presence of heavy metals is one of the main obstacles for agricultural use of dewatered sewage sludge produced in wastewater treatment plants. As one of the most promising and green methods, electrokinetic remediation technology (ERT) offers high efficiency, time-effectiveness and low operational expenses in removal of heavy metals from the matter with lower hydraulic permeability such as sludges. A review was presented addressing pesent studies on basic principle, removal efficiency and impact factors of ERT for deconminating sewage sludge with heavy metals. The exiting problems in application of ERT for heavy metals removal from sewage sludge were discussed, and future research directions were also proposed. |
