Description
Technical field
The present invention relates to a kind of water and emit a little, and water emit a little and network of rivers network (or network of rivers) in effectively stop bacterial growth, particularly stop water emit a little and network of rivers network in Legionella grow.
Background technique
A known problem in discharging water a little is, especially hot water space and mixer chamber (or mixing chamber) have constituted an environment that the particularly fearful Legionella of aquatic bacteria is grown, if water temperature is approximately 35 ℃, then number of bacteria can increase by 10000 times at most in 48 hours.Legionella circulates in water unlike the free living biology, its still for example find in the inboard of water tank, water pipe and mixer one unusual part of complicated microenvironment.The biomembrane (biofilm) that is made of microorganism becomes the mucus of a thin layer, and shockingly resists the influence that is specifically designed to the biocide that stops bacterial growth.Biocide can kill the bacterium of the free living in the water effectively, but the bacterium in the biomembrane often survives, in case and conditions permit just begin in water, to breed.This " hiding " ability makes some bacterium, is difficult to effectively control as Legionella.This problem is increasing, may be relevant with using more widely of modern comfort, and these modern comforts have some spaces, wherein with the water cooling of stagnating or be heated to harmful temperature range of 25-50 ℃.Exemplary of this equipment and the potential source of bacterium are that modern temperature is regulated mixer.Bacterial growth is considered to stop when the temperature that is higher than 50 ℃.
Recently the trial that addresses this problem is comprised such mixer, wherein the operator can use special tool to wash away mixer and water system a few minutes with scalding hot water temporarily, and purpose is that for example whole the discharging water in hospital or medical institutions a little killed bacterium.Also advised a kind of computer control automatic system of regularly washing away mixer with hot water.Further practice shows, can realize Disinfection Effect by the water with oxidation biocide such as chlorine, bromine or ozone without interruption.For example instructed flushing method in the U. S. Patent 6027572 of reference herein.But all these processes all need large quantities of manpowers, thereby need spend on the service operations person in the hospital for example.In addition, the activity in the clinic will be upset.
Other trial that solves problem of bacteria be in the jettison gear or near water purify.Method and apparatus comprises to be dosed ozone (seeing U. S. Patent 5942125), uses a plurality of filters (seeing U. S. Patent 5851388), dose antimicrobial agent (seeing U. S. Patent 5709546) and by disinfection by ultraviolet light (seeing U. S. Patent 5891329) by pumping installations.Although effective in some applications, as in dentist's office, their complexity make their not too be fit to main equipment with needing to safeguard, as all jettison gears in hospital or the residential building.In addition, it also is suspectable water being purified and do not solve the problem that bacterium grows fast in follow-up phase.
