Preparation method and odor controlling method for antibacterial deodorizing functional film for domestic garbage

Abstract

The invention relates to a preparation method and an application method of an antibacterial deodorizing functional film for inhibiting the bacterial activity of domestic garbage. Film forming liquid is prepared from the following components in percentage by mass: 15-40% of film forming reagents, 0.05-1.0% of antibacterial deodorizing agents, 1-2% of acidity adjusting agents and 10-15% of film forming aids. The preparation method includes the steps of adding the acidity adjusting agents into a water and ethanol mixture, stirring, adding the antibacterial deodorizing agents, reducing the stirring speed after quick stirring, sequentially adding the film forming aids and the film forming reagents, and performing uniform stirring to obtain the antibacterial deodorizing film forming liquid. A layer of non-woven cloth is paved on the surface of the garbage, the film forming liquid is sprayed onto the surface of the non-woven cloth to rapidly form the film, antibacterial agents in the film arecontinuously released while dispersion of malodorous substances is effectively suppressed, the activity of bacteria on the surface of the garbage can be effectively inhibited, and accordingly, generation of the malodorous substances is slowed down; through the antibacterial deodorizing functional film, generation and release of the foul odor of the garbage can be effectively controlled, and the foul odor from garbage storage, garbage transportation and landfill working surfaces is eliminated on site.

Description

technical field [0001] The invention relates to the technical field of domestic garbage treatment, in particular to a method for inhibiting bacteria and controlling odor of garbage. Background technique [0002] It often takes 1-3 days for domestic waste to be dumped, collected and transported into the landfill. During this process, when the oxygen is sufficient, the perishable organic matter in the waste will be decomposed under the action of aerobic bacteria, producing many A kind of oxidizing and corrupting substances, such as: ammonia and various small molecule organic acids, etc.; when the oxygen is insufficient, the perishable organic matter will be decomposed into incomplete oxidation products under the action of anaerobic or facultative bacteria, such as: H 2 S, mercaptans, amines and phthalamides and other substances. During the process of garbage collection and transportation, aerobic and anaerobic alternate or exist at the same time, releasing a large number of p...

[0006] The Chinese patent CN 105331028 A, which is similar to the basic mechanism of these patents, discloses a "medicine for controlling the source of domestic waste odor and its preparation and use", which uses polyvinyl alcohol, polyvinylpyrrolidone, hydroxypropyl Methyl cellulose film-forming liquid is sprayed on the surface of the garbage to inhibit the release of odor through physical barrier effect, but this method does not have the effect of inhibiting microbial activity and controlling the release of odor, and the surface of the garbage heap is poor in flatness and complete film formation not ideal

Chinese patent CN 105331028 A discloses "A Deodorant". First, a bactericide and a stabilizer are made into a liquid A, a gel and an acid-base regulator are made into a liquid B, and the liquids A and B are sprayed on the garbage in sequence. The surface is formed into a film to sterilize and block the spread of odor. However, in this method, the two liquids are prepared separately, and the operation is cumbersome, and the surface of the garbage dump is rough and uneven. It is difficult for the spray liquid to touch the odor release point inside the garbage dump. It is also difficult to form a complete and sealed film on the surface of the garbage pile by spraying in sequence
