Problems solved by technology

Waste plastic residues in the soil will not only cause the soil itself to be unable to digest and degrade waste plastics, but also have a fatal impact on the beneficial bacteria in the soil and soil porosity and air permeability, thereby destroying the soil ecosystem. In the long run, waste plastic residues will gradually cause soil pollution. Hardening, ecological disorder of flora, fertility loss, soil erosion and other problems

Abstract

The invention relates to a plastic degradation agent for alkaline soil remediation and a preparation method thereof. The plastic degradation agent for alkaline soil remediation is prepared from a graphene / zinc sulfide / manganese sulfide / titanium dioxide photocatalyst, a pretreating agent, an enzyme preparation, boric acid and citric acid, and the graphene / zinc sulfide / manganese sulfide / titanium dioxide photocatalyst is prepared by reacting tetrabutyl titanate, zinc acetate, manganese acetate, a graphene ethanol solution, water, polythiourea, acrylic acid and ethanol through reaction. The pretreating agent is prepared by reaction of 2-acrylamide-2-methylpropanesulfonic acid, acrylic acid, butyl acrylate, vinyl acetate, water, ethanol, a 819 photoinitiator and an Sr-10 emulsifier, and the enzyme preparation is prepared by reaction of extracellular hydrolase, dioxygenase, monooxygenase, oxidoreductase, bone enzyme, fatty acid oxidase, carbomer resin, bone meal and water. The plastic degradation agent for alkaline soil remediation has excellent plastic degradation performance.

Description

technical field [0001] The invention relates to the field of soil restoration, in particular to a plastic degradation agent for alkaline soil restoration and a preparation method thereof. Background technique [0002] With the application and popularization of plastic technology in the agricultural production process, the recycling of waste plastics produced in the agricultural production process and the problems of remaining in the soil that are difficult to degrade have gradually attracted the attention of agricultural production. Waste plastic residues in the soil will not only cause the soil itself to be unable to digest and degrade waste plastics, but also have a fatal impact on the beneficial bacteria in the soil and soil porosity and air permeability, thereby destroying the soil ecosystem. In the long run, waste plastic residues will gradually cause soil pollution. Hardening, ecological disorder of flora, loss of fertility, soil erosion and other problems. In order t...
