Soil remediation agent for removing organic phosphorus pollution, preparation method and applications thereof

Abstract

The invention belongs to the field of soil remediation, and discloses a soil remediation agent for removing organic phosphorus pollution, a preparation method and applications thereof. The soil remediation agent comprises 11-17 parts of beta-1,3-1,4-glucan, 3-6 parts of magnesium carbonate, 2-5 parts of aluminum silicate, 3-6 parts of potassium dichromate, 4-9 parts of hydroxybutyl cellulose, 5-10 parts of vermiculite powder, 2-6 parts of citric acid, 3-5 parts of EDTA, and 1-3 parts of lithium carbonate. The preparation method comprises: crushing magnesium carbonate, aluminum silicate, vermiculite powder and lithium carbonate into powder, respectively taking the beta-1,3-1,4-glucan, the magnesium carbonate, the aluminum silicate, the potassium dichromate, the hydroxybutyl cellulose, the vermiculite powder, the citric acid, the EDTA and 1-3 parts of the lithium carbonate according to the weight ratio, carrying out mechanical stirring on the raw materials, and stirring until uniformly mixing the components so as to prepare the soil remediation agent for removing organic phosphorus pollution.

Description

technical field [0001] The invention belongs to the field of soil remediation, and relates to a soil remediation agent and its preparation method and application, in particular to a soil remediation agent for removing organic phosphorus pollution and its preparation method and application. Background technique [0002] Most organophosphorus pesticides are oily or crystalline, and industrial products are light yellow to brown. Except for trichlorfon and dichlorvos, most of them have garlic odor. Generally insoluble in water, easily soluble in organic solvents such as benzene, acetone, ether, triazine and oils, relatively stable to light, heat and oxygen, easy to decompose and destroy when encountering alkali, except for trichlorfon, which is white Crystallization, soluble in water. There are many kinds of organophosphorus pesticides, which are often divided into three categories, which are highly toxic (such as: phorate, demeton, parathion, Baomianfeng, omethoate); highly to...

Problems solved by technology

[0004] Technical problem to be solved: In some soils with very serious organophosphorus pesticide residues, the content of methyl parathion, phorate, and methapon is relatively high, and some are as high as 100mg / Kg to 200mg / Kg, but they can effectively reduce the methyl parathion in polluted soil. The remediation method of parathion, phorate, methapion content is less, and the purpose of the present invention is exactly to provide a kind of new soil remediation agent that is used to reduce organic phosphorus pollution, effectively reduces methyl parathion, Pollution of phorate and methapon
