Embodiment 1
[0043] Grind the raw materials potassium permanganate, ferric sulfate and bentonite into a material with a particle size of not less than 200 meshes, weigh according to mass percentage: potassium permanganate is 15%, ferric sulfate is 60%, and bentonite is 25%, then mix evenly, That is, the repairing agent is obtained.
Embodiment 2
[0045] Grind the raw materials potassium permanganate, ferric sulfate and bentonite into a material with a particle size of not less than 200 meshes, weigh according to the mass percentage: 7% of potassium permanganate, 43% of ferric sulfate, and 50% of bentonite, then mix evenly, That is, the repairing agent is obtained.
Embodiment 3
[0047] Grind the raw materials sodium hypochlorite, potassium perchlorate, ferric sulfate, ferric chloride, Portland cement and active pozzolan into materials with a particle size of not less than 200 mesh, mix sodium hypochlorite and potassium perchlorate in any proportion to form component A, and mix ferric sulfate and chlorine Mix ferric iron into component B according to any proportion, mix portland cement and active pozzolan into component C according to any proportion, and then weigh according to mass percentage: component A is 15%, component B is 40%, Component C is 45%, and then mixed evenly to obtain the repairing agent.
[0048] On the basis of Example 3, by changing the composition of components A, B, and C, many examples can be evolved, and the details will not be repeated.
[0049] The use method of repairing medicine Laboratory Example 1:
[0050] 100 kg of arsenic-contaminated soil was taken from a mining area in Shimen County, Hunan Province.
