Abstract: Mechanochemisty, is considered as one of the promising technologies for degradation of persistent organic pollutants (POPs) due to its rapid development and versatile applications. The mild reaction conditions and unique advantages such as complete reaction, less demand for solvents, low cost and almost no secondary pollution attract more and more attention from researchers. The paper summarizes the source and the mechanism of mechanochemistry such as plasma model and the generation of electron undergone bond breakage and lattice defect for promoting the reaction. The previous research of mechanochemistry in environmental protection such as pollutants decomposition and disposal and waste materials utilization are introduced and commented especially on the development of POPs treatment in the aspect of main reagents, chlorinated persistent organic pollutants and other persistent organic pollutants, etc. The representative reaction mechanism of the process is described in details. Further research for the promotion of mechanochemical degradation of POPs and the contaminant soil is proposed.
