Description

A kind of method to indoor environment fumigation

Technical field

The present invention relates to sterilization method, and in particular to a kind of method to indoor environment fumigation.

Background technology

Fumigation technology is the disinfectants such as Peracetic acid, formaldehyde is switched to gaseous state using modes such as heating, is volatized into Closed place kills off the insect pests, the technical measures of pathogenic microorganism or other harmful organisms.Fumigation great advantage is stifling medicine Thing can be uniformly distributed in each corner of indoor environment, and the comprehensive thorough and save trouble and labor of sterilization is particularly well-suited to room air The sterilization of pollution, is widely used in the ground such as biological, medical laboratory, slaughterhouse, plant.Conventional fumigation method has two Kind.One kind is formalin+potassium permanganate fumigation, and this method is using concentrated formaldehyde solution (formalin) and potassium permanganate There is the substantial amounts of heat produced during redox reaction, formaldehyde therein is heated and be volatized into air, then using first Aldehyde can make the principle that microprotein denaturation solidifies to kill the bacterial propagule in body surface and air, brood cell, fungi With virus etc..Another kind is Peracetic acid fumigation, mainly uses the method for heating and peroxide acetate aqueous solution is volatilized Air inlet is sterilized, and Peracetic acid belongs to peroxide disinfectant, and it has Strong oxdiative ability, can effectively kill various bacteriums Brood body, mycobacteria, bacterial spore, fungi, algae and virus, it is also possible to destroy bacteriotoxin.

All there is shortcoming in both the above sterilization method, constrain its application in production practices.Formalin+permanganic acid Potassium fumigation is adapted to the sterilization in smaller space, and does not apply to large space such as plant livestock and poultry colony house, and reason exists In formalin+potassium permanganate fumigation reaction once formaldehyde quickly volatilizees, full of whole space, it is impossible to control Reaction speed, personnel have little time to withdraw.The Peracetic acid that Peracetic acid fumigation is used is because easily decomposes must now use Now match somebody with somebody, and configure two kinds of solution of Peracetic acid, one kind is hydrogen peroxide+concentrated sulfuric acid, and another kind is glacial acetic acid, both liquid Splash and blast are easy in mixing, than relatively hazardous, Peracetic acid has corrosivity in addition, can make commonly using this method for operation Metal chlorination equipment oxidation and rusting.
