Problems solved by technology

[0002] At present, daily disinfection is mainly based on chemical decontamination, which has high-efficiency disinfection effects. There are many types of chemical disinfectants, mainly hydrogen peroxide, peracetic acid, 84 disinfectant, and chlorine dioxide. Due to the complexity, the daily chemical disinfection methods are often unable to quickly and efficiently complete the disinfection tasks in public safety and health incidents, resulting in the problem of secondary pollution caused by inadequate disinfection, and secondary disasters caused by excessive disinfection, which affect the health of the people. Safety of life and property
[0003] So far, there is no efficient disinfection method that can meet the disinfection needs of complex and changeable environments in public safety and health events

Embodiment 1

[0113] Quantitative sterilization experiment, the specific steps are as follows:

[0114] Disinfection group: suck 5mL of the disinfectant solution into a sterile test tube, pipette 20μL of the bacterial suspension into the disinfectant solution with a micropipette, and let it act for a specified time, then immediately pipette 0.5mL of the reaction solution into a test tube containing 4.5mL of neutralizer Medium; after shaking and mixing, draw 0.5mL of the final sample solution and inoculate it on a nutrient agar plate, culture it in a 37°C incubator for 48 hours, and count viable bacteria. The experiment was repeated 3 times.

[0115] Control group: draw 5mL of the diluent into a sterile test tube, pipette 20μL of the bacterial suspension into the diluent with a micropipette, let it react for a specified time, and immediately pipette 0.5mL of the reaction solution into the test tube containing 4.5mL of the diluent; After 10-fold serial dilution, select a suitable dilution su...

Embodiment 2

[0120] The structure of the decontaminator used in this embodiment is as attached figure 1 As shown, the fan speed of the decontaminator is divided into three gears of "high, medium and low", and the standard speed is 6800r / min; the liquid control switch is divided into three gears of "1, 2, 3" from small to large . The spraying speed and spraying density of the disinfectant are inherent parameters of the sterilizer, which are determined by the speed of the fan and the liquid output, as shown in Table 2.

[0121] Table 2

[0122]

[0123] Note: The spraying amount of disinfectant is the product of the spraying density and the spraying time.

[0124] The specific experimental steps of using the above-mentioned sterilizer to carry out the disinfection experiment are as follows:

[0125] 1) Cloth bacteria: Weigh 10g of sterile soil into a sterile petri dish (diameter 8cm); secondly, pipette 100μL of bacterial suspension with a 10-100μL micropipette, and drop it on the surface...

Embodiment 3

[0137] The decontamination device used in embodiment 3 is the same as that in embodiment 2. Using the disinfector to disinfect the surface of the equipment coating, the disinfectants used are: bleaching powder disinfectant with a mass content of calcium hypochlorite of 1%, hydrogen peroxide with a mass content of 5% Disinfectant or chlorine dioxide and chlorine dioxide disinfectant with a mass content of 20%. The specific experimental steps are as follows:

[0138] 1) Cloth bacteria: Use a 10-100μL micropipette to pipette 100μL of bacterial suspension, and apply it on the surface of the equipment coating (the area is about 30cm 2 ), the number of infection points is greater than 20.

[0139] 2) Disinfection group: basically the same as in Example 2, the difference is: open the air flow control valve to the mid-range, then open the liquid medicine flow control valve to the 2nd gear; stop spraying the disinfectant aerosol after the spraying time is 20s; The sample is placed, ...

Abstract

The invention provides a disinfection method. In the disinfection method of the invention, the disinfection solution is sprayed onto the disinfection object for disinfection. On the one hand, the output volume of the disinfection solution is regulated to control the spraying speed and the spraying amount of the disinfection solution. Specifically, when the disinfection target is soil , control the spray speed of the above-mentioned disinfectant to be 400mL / min~520mL / min, and the spray volume of the disinfectant to be 980mL / m 2 ~3000mL / m 2 ; When the disinfection object is a coating, control the spraying speed of the above-mentioned disinfectant to 300mL / min-380mL / min, and the spraying volume of the disinfectant to 300mL / m 2 ~610mL / m 2 ; When the object of disinfection is tiles, control the spraying speed of disinfectant to 50mL / min-200mL / min, and the spraying volume of disinfectant to 50mL / m 2 ~400mL / m 2 On the other hand, the content of active ingredients in the disinfectant is controlled, and various process conditions work together to achieve high-efficiency disinfection while avoiding secondary disasters caused by excessive disinfection and ensuring personal safety.
