Description
Technical field
The utility model relates to killing legionella technical field, particularly relates to a kind of device of killing legionella in fluid medium.
Background technology
In the members of Philadelphia legion of the U.S. in 1976, once breaking out febris acuta respiratory tract disease, is known the first explosion, has 221 people to catch, wherein 34 people's death.Because most the dead is legionnaire, be therefore called legionnaires disease or veteran's disease.Retrospective research finds to have as far back as nineteen forty-three the case of legionnaires disease, and by the bacterium called after legionella pneumophilia of these case-findings of research, many Related Bacteria are subsequently put into this genus temporarily afterwards.Now proposed to exceed 30 kinds of Legionnella, at least 19 kinds is the pathogenic agent of people's parapneumonia.Wherein modal pathogenic agent is legionella pneumophilia (accounting for the 85%-90% of case), next is L.micdadei (accounting for 5%-10%), is L.bozemanii and L.dumoffii again, and this type of ne ar is similar, there is common biochemical character, cause similar disease.Legionnaires disease accounts for the 1%-8% of the community acquired pneumonia that needs hospital care, accounts for 4% left and right of lethality hospital acquired pneumonia, and most of cases are sporadic, multiple be born in late summer and autumn at the beginning of.
Artificial water application's system can provide living environment for the amount reproduction of Legionnella, as the cooling tower of shower, mineral spring pond, fountain and conditioning unit.The concern of the whole society to air-conditioning legionella causes in 2003 generation SARS in China, after bird flu in 2006, the Ministry of Health puts into effect " central air conditioning hygiene control way " and " public place centralized air ventilation system hygienic practice ", requires must not detect legionella pneumophilia in cooling circulating water system and water of condensation.But run from being designed into the later stage in engineering project, all without relevant treatment measure.In the more than 70% central air-conditioning cooling circulating water system of China, all detect legionella pneumophilia at present.Along with the development of China's Urbanization Construction, the generally application of life secondary water-supply, life heating agent centralizedly supply, the warm air-conditioning system of centralized confession, public health security in the serious threat that exists of legionella.
The method of existing killing legionella has chemical sterilization method, ultra-violet sterilization method, membrane-filter procedure etc.Traditional chemical sterilization method adopts chlorine, dioxide peroxide, sodium-chlor, the sterilization of Losantin solvent mostly, and must first clean water pipe before using these chemical, so this method is complicated operation not only, and corrosive medium diversing flow system, and exist media discharge to cause the defect of secondary pollution.By irradiating shortwave (as wavelength 254 nanometers), ultraviolet ray can make germ enliven to ultra-violet sterilization method, but germ may be present in amoeba.The particle (comprising bacterium, even partly viral) that membrane-filter procedure generally can utilize the micropore of film that diameter is less than to 0.2 nanometer filters out.Ultra-violet sterilization method and membrane-filter procedure are all that legionella is shifted and can not thoroughly be eradicated, and have environmentally hazardous problem.
As can be seen here, above-mentioned existing legionella killing method obviously still has a lot of defects, is urgently further improved.How to found a kind of thorough killing legionella, environment is not caused to secondary pollution and the device of killing legionella in fluid medium easy and simple to handle, real one of the current important research and development problem that belongs to.
