a1, adding beta-cyclodextrin into boiling water to prepare a saturated aqueous solution, and recrystallizing for three times to obtain the beta-cyclodextrin with the purity of more than or equal to 99.9 percent;
2, adding the beta-cyclodextrin purified in the step a into distilled water at room temperature to prepare a beta-cyclodextrin saturated aqueous solution; adding NaOH with 2 times of the molar weight of the cyclodextrin, and stirring for 5-8 minutes;
a3, slowly dripping epoxy chloropropane with the same molar weight as the beta-cyclodextrin into the step b under stirring, and reacting for 40-50 minutes;
and A4, dissolving amino acid with the same molar weight as the beta-cyclodextrin in water, slowly dripping the amino acid into the step c, stirring the mixture to react for 40 to 50 minutes, spin-drying the mixture, and adding ethanol to wash the mixture for 3 to 4 times to obtain the modified beta-cyclodextrin.
A preparation method of an agricultural sewage treatment agent comprises the following steps:
s1: adding a mixture of an adsorbent, sodium alginate, a carbon nano tube, modified beta-cyclodextrin, sepiolite, cellulose, aluminum oxide powder, sodium chlorate, propisochlor, ferrous chloride, zinc stearate, sodium carbonate, pinoxaden, thiobacillus denitrificans and carbonate into purified water for full dissolution, wherein the weight of the purified water is 3-4 times of the total weight of the substances, and obtaining a first mixed solution;
s2: and adding the flocculating agent, the chlorophyll and the bactericide into purified water for dissolving, wherein the weight of the purified water is 5-8 times of the total weight of the three substances, and obtaining a second mixed solution.
S3: and dropwise adding the second mixed solution into the first mixed solution while stirring.
In a preferred embodiment, the dropping time in S3 is: 1-2h, stirring speed: 50-80 r/min.
The technical scheme of the invention has the beneficial effects that:
the agricultural sewage treatment agent prepared by the method has obvious effects on conveniently removing BOD, COD, ammonia and organophosphorus pesticides. Meanwhile, the pH value of the water body can be improved, so that the water body can be recycled. When the water treatment agent is used, the water treatment agent only needs to be added into a water body for standing, the use is convenient, and the difficulty of agricultural sewage treatment is reduced.
The water treatment agent uses the carbon nano tube and the modified beta-cyclodextrin, carbon atoms in the carbon nano tube are mainly hybridized by sp2, no matter the single-wall carbon nano tube or the multi-wall carbon nano tube, the surface of the carbon nano tube is combined with a certain functional group, due to the protection effect of the surface group of the carbon nano tube, the nano Ag + is uniformly dispersed on the surface of the CNT, and meanwhile, the large specific surface area of the carbon nano tube enhances the adsorption effect of the silver nano particles. The modified beta-cyclodextrin is in a cylindrical structure, both ends and the outside of the modified beta-cyclodextrin are hydrophilic, the inside of the cylinder is hydrophobic, and some molecules with proper size and shape are contained in the annular structure by van der Waals force to form the microcapsule-shaped inclusion compound. The water-insoluble molecules are embedded in the cavity of the cyclodextrin to increase the solubility of the cyclodextrin in water.
