Problems solved by technology

These wastes are difficult to degrade and rot in the natural environment or garbage dumps, and they are large in quantity, scattered, difficult to recycle, and seriously polluted
At present, foreign countries generally adopt three methods of landfill, incineration and recycling to deal with plastic waste. However, landfill treatment has long-term harm to limited land resources, and incineration treatment will produce a large amount of harmful gases. The utilization method not only requires the collection and sorting of plastics, but also is not economically cost-effective, and it is difficult to promote for a while. In order to solve the problem of plastic waste disposal, degradable plastic products have attracted widespread attention due to their ideal environmental adaptability.

Abstract

The invention relates to a plastic garbage degradation treatment agent and a preparation method thereof, and belongs to the technical field of plastic garbage treatment. The preparation method comprises the following steps: firstly, taking polyhydroxy nanocellulose as a raw material, mixing the polyhydroxy nanocellulose with sodium silicate, adding hydrochloric acid, reacting and filtering to obtain filter residues, carrying out high-temperature reaction on the filter residues to obtain a degradation agent matrix, mixing mussel mucin liquid with the degradation agent matrix, adding catechol oxidase under an alkaline condition, reacting to obtain a modified degradation agent matrix, mixing the modified degradation agent matrix with ferric chloride and pulverized coal, reacting, filtering, and drying to obtain the plastic garbage degradation treatment agent. The plastic garbage degradation treatment agent has wide application prospects.

Description

technical field [0001] The invention relates to a plastic waste degradation treatment agent and a preparation method thereof, belonging to the technical field of plastic waste treatment. Background technique [0002] At present, the world's total plastic output has exceeded 150 million tons, and it has become the four pillar materials alongside steel, wood, and cement. However, with the increasing use of plastics, the white pollution caused by waste plastics has become a worldwide public hazard. The global "white pollution" problem has become increasingly prominent. These wastes are difficult to degrade and rot in the natural environment or garbage dumps, and they are large in quantity, scattered, difficult to recycle, and seriously polluted. At present, foreign countries generally adopt three methods of landfill, incineration and recycling to deal with plastic waste. However, landfill treatment has long-term harm to limited land resources, and incineration treatment will ...
