▎ 摘　　要

NOVELTY - Insitu repairing agent comprises 30-40 pts. wt. platinum/titanium dioxide modified porous silkworm excrement, 2-6 pts. wt. graphene, 1-5 pts. wt. cation exchange resin, 4-6 pts. wt. methyl Bacillus and 4-6 pts. wt. Pseudomonas sinensis, where the platinum/titanium dioxide modified porous silkworm excrement is prepared by swelling the raw silkworm excrement through urea, carbonizing, carrying out quenching on the bromoplatinum acid and tetrabutyl titanate, and finally roasting the mixture at 450-500 degrees C to prepare the product, and successively subculturing methyl Bacillus and P.sinensis from carrying out continuous passage and domestication on original strains in a tetracycline-containing basic solid culture medium using original strains. USE - The repairing agent is useful for degrading tetracycline antibiotics in soil. ADVANTAGE - The repairing agent can directly repair the soil contaminated by tetracycline antibiotics in situ, has a short cycle, and combines physical adsorption, photocatalytic degradation and biodegradation to remove in situ, and the conversion rate is high. DETAILED DESCRIPTION - An independent claim is included for the insitu repairing agent comp-rising mixing platinum/titanium dioxide modified porous silkworm excrement, graphene, cation exchange resin, methyl Bacillus and P.sinensis.
