Petroleum soil adsorption-degradation modified material
The invention relates to a production method of a petroleum soil adsorption-degradation modified material. The method comprises the following steps: 1, drying, mixing and conducting coarse crushing on attapulgite, bentonite and diatomite ore; 2, adding cetyltrimethylammonium bromide and a titanate coupling agent, mixing, spraying water, and extruding into a sheet clay mixture; 3, piling, drying, fragmenting and grinding the sheet clay mixture to obtain a powder; 4, adding the sheet clay mixture in a beating tank, adding sodium pyrophosphate, beating and shearing; 5, grading, adding titanium tetrachloride and ammonium sulfate, sealing, insulating, reacting and adjusting the pH; 6, conducting pressure filtration, calcination, crushing and grinding to obtain a powder; and 7, mixing the powders in step 3 and step 6. The minerals used in the present invention have low cost, the steps are simple, and the obtained petroleum soil adsorption-degradation modified material has significantly improved adsorption and degradation effect of petroleum hydrocarbons in soil, and is applicable to large-scale application.
