The invention relates to a method for degrading the chloride, which comprises the following steps: firstly the surface of the hollow glass micro balloon is loaded with the iron and nickel dual-metal particles so as to modify the surface of the hollow glass micro balloon in liquid-phaseelectroless plating way; secondly, the modified hollow glass micro balloon is adopted as the absorption agent, the restoration agent and the catalyst to degrade the organic chloride. On the one hand, the problem of the load of the catalyst (Fe-Ni) is resolved; on the other hand, the surface area of the catalyst is enlarged, so that the active center of the reaction is increased; moreover, after heating and promoting with the micro wave in the reaction, a plurality of heat points can be generated on the surface of the hollow glass micro balloon, thereby greatly improving the absorption efficiency of the micro-wave energy. Under the cooperative effect of the absorption of the modified hollow glass micro balloon and the inducement of the micro wave, the degradation of the organic chloride is more efficient and more thorough. The method is simple to be operated, and is free from generating the toxic intermediate bodies, and has good effect to degrade the organic chloride, and is a good method for processing the organic chloride waste water.
