PROBLEM TO BE SOLVED: To provide a treatment method of a solid waste in the method for treating solid waste such as incineration ash, soot dust, slag, sludge, soil and the like containing a toxifying metal by adding a metal scavenger thereto and immobilizing the metal with the metal scavenger to detoxify, which solves the problems in the conventional method that can not scavenge the metal in the solid waste accurately due to the insufficient permeability of the metal scavenger to solid waste, suffers low immobilization property of the metal with the metal scavenger having high permeability to the solid waste and causes the elution of the immobilized metal when calcium which has not been immobilized is eluted because calcium in the solid waste can not be immobilized, and further needs complicated procedures for removing the sticked solid waste because the waste treated by the conventional method is easy to stick to a tranferring device and a processing device. SOLUTION: The solid waste treatment agent is composed of an acidic compound, at least one surfactant selected from an anionic surfactant, an amphoteric surfactant and an acid base of an amphoteric surfactant and the metal scavenger.
