Embodiment 1

[0028] A plastic degradation process is characterized in that it comprises the following specific steps:

[0029] S1. Sieve the collected plastic raw materials, clean them, and perform mechanical destruction to reduce their volume;

[0030] S2. Put the pretreated raw materials into the soaking solution for soaking for 24 hours, and keep the soaking temperature at 37°C;

[0031] S3. Cleaning the soaked raw materials, adding them to the fermenter for fermentation and degradation;

[0032] S4. Collect the degraded mixed solution, waiting for secondary extraction and recycling.

[0033] The soaking solution in the step S2 includes the following components in parts by weight: calcium hydroxide 8, sodium hydroxide 6, ammonium chloride 13, ammonium bicarbonate 11, triethanolamine 9, polyethylene glycol 2.

[0034] Further, the concentration of the soaking solution is 0.15moL / L.

[0035] The soaking solution in the present invention can be combined with the functional groups of the...

Abstract

The invention provides a plastic degradation process, wherein the plastic degradation process includes the following specific steps: S1, sieving a collected plastic raw material, cleaning cleanly, andcarrying out mechanical destruction to reduce the size; S2, putting the pretreated raw material in a soaking liquid, carrying out soaking treatment for 24-72 h, and keeping the soaking temperature at37-60 DEG C; S3, cleaning the soaked raw material, adding into a fermentation tank, and carrying out fermentation degradation; and S4, collecting the degraded mixed liquid, and waiting for secondaryextraction and recycling. The plastic can be easily recycled and reused; the waste plastic after recycling can again become a product and also can be used for preparing gasoline and diesel after beingtreated; and the environmental and social problems brought by plastic pollution are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a plastic degradation process. Background technique [0002] Nowadays, the pace of life and work is getting faster and faster. Ordering a takeaway through a mobile app has become a convenient choice for a full stomach. China has also become the country with the largest number of food delivery in the world. But most people may not have expected that food delivery puts great pressure on the environment-the take-out box with an average use time of only 1 hour may take hundreds of years to degrade naturally. [0003] The ultra-thin plastic bags that were once widely used disappeared due to the "Plastic Restriction Order". Ten years after the "Plastic Restriction Order" was issued, lunch boxes made of non-degradable plastics have become a new source of plastic waste pollution. [0004] Every day, the "riders" of the Internet's third-party food delivery ...
