Embodiment 1

[0026] A processing method for plastic pollution, characterized in that it comprises the following specific steps:

[0027] S1. Sieve the collected plastic raw materials, clean them, and perform mechanical destruction to reduce their volume;

[0028] S2. Put the pretreated raw materials into the soaking solution for soaking for 24 hours, and keep the soaking temperature at 37°C;

[0029] S3. Cleaning the soaked raw materials, adding them to the fermenter for fermentation and degradation;

[0030] S4. Collect the degraded mixed solution, waiting for secondary extraction and recycling.

[0031] The soaking liquid in the step S2 includes the following components in parts by weight: calcium hydroxide 5, sodium hydroxide 4, ammonium chloride 8, ammonium bicarbonate 9, triethanolamine 6, and isopropanol 4.

[0032] Further, the concentration of the soaking solution is 0.1LmoL / L.

[0033] The soaking solution in the present invention can be combined with the functional groups of t...

Abstract

The invention provides a treatment method for plastic pollution, wherein the treatment method 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 processing method for plastic pollution. Background technique [0002] Ordering takeaway during busy work and bad weather has become the norm for many people. However, with the surge in takeout volume, the packaging boxes and bags consumed by takeout are also getting bigger and bigger. The ensuing white pollution has also attracted everyone's attention. [0003] The report on the development of China's food delivery O2O industry shows that in 2016, the proportion of online food delivery users who consumed more than 3 times a week reached 63.3%. According to this consumption pattern, at least 400 million takeaways are delivered every week, resulting in the waste of 400 million disposable packing boxes and disposable tableware. Takeaway disposable tableware has become a new "white pollution". In this regard, Xie Yufeng, a researcher at the Shaan...
