Description
Technical field
The invention belongs to municipal sewage treatment sterilization field, specifically, relate to a kind of photocatalysis disinfection reactor of sterilizing for reuse water and rainwater.
Background technology
Urban sewage reutilization and rainwater utilization be alleviate water pollution, the effective way of Urban Water Shortage Problem of Cities of improving the ecological environment, solve, having very large Exploitative potential, is the Strategic solving water scarcity problem.Reuse water and the rainwater utilization health risk possible to human body are one of focal issues of current public attention, the microbiological hazards problem especially in reclaimed wastewater reuse process.Substantially bacterium is divided into the pathogenic micro-organism that HUMAN HEALTH works the mischief, several classes such as bacterial parasite (parasite and protozoon) and virus.Pathogenic micro-organism can cause great harm to population health, therefore, is necessary very much to take effective disinfectant measure to ensure the biological safety of reuse water.Reuse water and rainwater are mainly used in the purposes such as miscellaneous water, water for scenic environment use, all propose Bacteriological Indexes requirement in the standard such as China " urban sewage reutilization urban reclaimed water water quality " (GB/T 18920-2002), " urban sewage reutilization water for scenic environment use water quality " (GB/T 18921-2002).Current mainly through chlorination, but the reuse water of dispersion and rainwater utilization facility are usually less, adopt liquid chlorine disinfection to need liquid chlorine storage tank, there is certain security risk, and due to some reuse waters and the intermittent operation of rainwater treatment facility, water yield fluctuation is large, requires higher to chlorination operational administrative.Therefore, research is a kind of efficient, and easy to operate, safe and reliable reuse water and rainwater disinfection apparatus have important practical for promotion Reclaimed Municipal Wastewater and rainwater utilization and be worth.
Be that the novel drinking water disinfection technology of core receives much concern with advanced oxidation, wherein UV/TiO
2photocatalysis disinfection technology is one of focus of water treatment field research.UV/TiO
2photochemical catalytic oxidation sterilization has the features such as nontoxic, broad spectrum sterilization, is a kind of promising alternative chlorine disinfectant technique.UV/TiO
2photocatalysis disinfection mechanism is that first the strong oxidizing property hydroxyl radical free radical (OH) that it produces destroys bacteria cell wall, then causes the Oxidative demage of cytolemma and born of the same parents' intracellular metabolite material and genetic material, finally causes necrocytosis and reach sterilization object.In water treatment applications, in order to avoid powder titanium dioxide be difficult to reclaim problem, mostly by titanium dichloride load on different carriers to realize immobilization.Porous sorptive material is adopted to be an important directions of current research as the carrier of titanium dioxide, as zeolite, gac, activated carbon fiber etc., can be concentrated to around titanium dioxide by target contaminant lower for body phase strength of solution, reaches the object improving light-catalyzed reaction efficiency.
Activated carbon fiber has abundant micropore and high specific surface area, its loading capacity far above other porous adsorbing materials, as zeolite, silica gel etc.; Loading capacity might as well than its like product gac.Because its form is generally felted or cloth-like, in practical application, be more convenient to the design ap-plication of reactor than granular carbon.
Domestic and international UV/TiO
2photocatalysis disinfection technical study is still in the starting stage, has domesticly carried out correlative study with regard to activated carbon fiber (ACF) carried titanium dioxide aspect at present.Such as, Chinese Patent Application No.: 200510035311.2, applying date: on November 30th, 2005, a kind of activated carbon fiber containing nano titanium dioxide particles of this disclosure of the invention and its production and use.This invention relates to a kind of activated carbon fiber containing nano titanium dioxide particles and its production and use.This activated carbon fiber is formed by nano titanium dioxide particles in activated carbon fiber material load, and wherein nano titanium dioxide particles accounts for 5 ﹣ 25% of total mass.This invention adopts sol-gel method, first by TiO
2presoma organic titanic compound through hydrolysis generate TiO
2colloidal sol, and be deposited in activated carbon fiber, drying sol becomes gel, then is converted into nano-TiO through thermal treatment
2particulate is compounded in the surface of activated carbon fiber, the obtained activated carbon fiber containing nano titanium dioxide particles.It had both maintained the porousness of activated carbon fiber, in turn enhanced titanium dioxide fine particles photocatalytic activity, can be used for the removal of low concentration gaseous volatile organic contaminant, was particularly useful for the Adsorption and decomposition of gaseous volatile organic pollutant in little space.It can reach 500mg/g to the loading capacity of gaseous volatile organic pollutant, can reach 36% to the photocatalysis Decomposition rate of light-concentration volatile organic pollutant.But this invention is just for gaseous state light-concentration volatile organic pollutant removal in air, the effect of process reuse water and rainwater is not remarkable.
With regard to current existing achievement in research, mainly concentrate on activated carbon fiber (ACF) carried titanium dioxide technique study and be applied to gas and Organic substance in water removal.In Water Disinfection, appear in the newspapers and be only limitted to other support materials load TiO
2pass through UV/TiO
2method carries out deactivation to the specific bacteria of artificial culture; Such as, Chinese Patent Application No.: 201010017224.5, the applying date: on 01 05th, 2010.A kind of ultraviolet/titanium dioxide (UV/TiO 2) reactor for disinfecting drinking water treated by activated carbon of this Invention Announce.The object of this invention is the Biosafety problem for bacterium in gac water outlet especially charcoal bacterium, proposes the ultraviolet titanium dioxide disinfecting reactor of charcoal bacterium in a kind of effluent water of drinking water activated carbon process.This reactor is at absorption UV sterilization advantage and TiO
2on the basis of catalysis characteristics, by the integrated decontamination reactor assembly of process optimization and integrated formation.UV/TiO
2(ultraviolet/titanium dioxide) disinfecting reactor can charcoal bacterium effectively in the water outlet of inactivation activities charcoal, and its process effluent quality reaches drinking water sanitary standard (GB5749-2006) requirement; And the water supply load change can born to a certain degree.But this invention just rests on theory stage, do not apply in actual applications so far.And the sheet glass support materials in this invention does not have absorption property, surface-area is large not, load TiO
2measure limited, the effect of process microbe species and more reuse water and rainwater is not very desirable.
Photocatalysis disinfection for the reuse water in practical application and rainwater is applied, and is not reported both at home and abroad.And adopt absorption property better, the UV/TiO of the ACF carried titanium dioxide that surface-area is larger
2photocatalysis disinfection reactor does not have report.So can UV/TiO be solved in the urgent need to one now
2photocatalysis disinfection reactor processes the scheme of reuse water and rainwater more ideally.
Summary of the invention
The problem that 1, will solve
Lack efficiently for prior art, the problem of easy to operate, safe and reliable reuse water and rainwater disinfection apparatus, the invention provides a kind of photocatalysis disinfection reactor of sterilizing for reuse water and rainwater, its UV/TiO sterilized for reuse water and rainwater
