Experimental device for researching plastic biodegradation

Abstract

The invention belongs to the technical field of plastic degradation, and provides an experimental device for researching plastic biodegradation. The experimental device comprises an incubator; containing cylinders arranged in the incubator; a crushing mechanism which is fixed to the inner wall of the incubator, is adjacent to the containing cylinders and is used for crushing the plastic with larger volume; a temperature and humidity control mechanism which is fixedly mounted in the middle of an incubator plate body, is positioned between the crossed containing cylinders and is used for controlling the temperature and humidity in the containing cylinders; and a plurality of ventilation mechanisms symmetrically arranged at the position, close to a top plate, of the incubator and used for periodically changing internal air. According to the device, the temperature and humidity control mechanism and the ventilation mechanisms are arranged, under the condition that the same environment is guaranteed, a plurality of groups of experiment samples are arranged, plastic degradation is compared according to different conditions in the samples, the influence of microorganisms on plastic degradation and the difference of the size of the plastic on the digestion and degradation of the microorganisms can be accurately obtained, so that the experiment accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of plastic degradation, and in particular relates to an experimental device for studying plastic biodegradation. Background technique [0002] Plastics are used very frequently in our lives, which brings convenience and also causes huge environmental pollution. Simply relying on nature to decompose, the cycle is extremely long. The existing plastic degradation methods include photodegradation and biodegradation. Among them, biodegradation refers to the degradation of plastics by using the action of microorganisms such as bacteria, mold and algae that exist in nature. [0003] When biodegrading plastics, existing devices usually simply place organisms in plastics to degrade plastics by organisms, but the existing devices cannot obtain accurate experiments on the impact of organisms on plastic degradation during experiments data.
