Embodiment 1

[0018] The raw garbage is first subjected to a rough sorting process, and the bamboo and wood packaging boxes and rubber tires are separated, and the large ones are broken;

[0019] The roughly sorted garbage is broken into bags, mixed and weighed, and mixed strains are added during the mixing process. After the strains are expanded and cultured, they are mixed according to the following volume ratio: Alcaligenes xylosoxidans subsp CGMCC 1.768: Bacillus amyloliquefaciens CGMCC 1.1177: Deinococcus radiodurans CGMCC 1.633: Debaryomyces hansenii CGMCC 2.1831: Rhizoma Issatchenkia scutulata CGMCC 2.1592, Aleuisma keratinophilum CGMCC 3.3544: Nocardiabrasiliensis CGMCC 4.1128=10:5:10:1:5:10. (2 x 10 per milliliter of liquid 7 more than one viable cell).

[0020] The mixed strains were diluted with water according to a volume ratio of 1:50, the diluted mixed strains were added according to 0.5% (V / W) of the garbage weight, and the fermentation was carried out for 5 days with venti...

Abstract

The invention discloses a method for treating plastic products for city trash. It comprises following steps: washing selected material with water, adding mixed bacteria and catalyst, what is characterized is that said mixed bacteria is Bacillus sphaericus CGMCC 1.1362, thermoduric bacteria CGMCC 1.1504, providencia CGMCC 1.1528, autotrophic Pseudonocardia CGMCC 4.1295. Compared with current tehcnique, the invention can degrade waste plastic material into fuel oil, about 6.5 ton per 10 ton waste plastic material, and the grade number of fuel oil is lower than that of normal fuel oil.

Description

Technical field: [0001] The invention belongs to the technical field of a method for processing plastic products in garbage. Background technique: [0002] With the development of economy, there are more and more urban garbage, and the biological recycling of garbage has become a new trend. Compared with the current landfill method and garbage incineration method, the biological garbage recycling method occupies less land and does not pollute the environment. Features. The biological recycling of garbage mainly includes the rough sorting process, the bag breaking process, the biological pretreatment process, the primary sorting process, the re-fermentation process, the secondary sorting process, the drying process, the selection process, and the organic fertilizer process. The raw garbage first goes through the rough sorting process, separates the bamboo and wood packaging boxes and rubber tires, and crushes the large ones; Treatment, the percolating water produced by biol...
