Embodiment 1

[0024] A solution to white pollution, characterized in that it comprises the following specific steps:

[0025] S1. Sieve the collected plastic raw materials, clean them, and perform mechanical destruction to reduce their volume;

[0026] S2. Put the pretreated raw materials into the soaking solution for soaking for 24 hours, and keep the soaking temperature at 37°C;

[0027] S3. Cleaning the soaked raw materials, adding them to the fermenter for fermentation and degradation;

[0028] S4. Collect the degraded mixed solution, waiting for secondary extraction and recycling.

[0029] The soaking liquid in the step S2 includes the following components in parts by weight: calcium hydroxide 7, sodium hydroxide 4, ammonium chloride 12-30, ammonium bicarbonate 15, triethanolamine 8, glycerol 4.

[0030] Further, the concentration of the soaking solution is 0.16moL / L.

[0031] The soaking solution in the present invention can be combined with the functional groups of the network ske...

Abstract

The invention provides a method for treating white pollution. The method comprises the following concrete steps: S1, screening and cleaning collected plastic raw materials, and carrying out mechanicaldamage to reduce the volume of the raw materials; S2, soaking the pretreated raw materials in a soaking solution for 24-72 hours and maintaining a soaking temperature to be 37-60 DEG C; S3, washing the soaked raw materials and adding the soaked raw materials into a fermentation tank for fermentation and degradation; and S4, collecting degraded mixed liquid for secondary extraction and recycling.The method of the invention allows the plastics to be conveniently and repeatedly recycled; after the waste plastics are recycled, the recycled plastics can be made into products again and can also beused for preparing gasoline and diesel oil; so environmental and social problems brought by plastic pollution can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a solution to white 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 Shaanxi Academy o...
