Abstract
The invention relates to an ozone water purifying method capable of reducing and eliminating bromates, which comprises three steps of pre-absorption filtering, ozone sterilization and disinfection and post-filtering. The method is characterized in that a filter material of the pre-filtering contains activated carbon or high-purity copper zinc alloy (KDF) or a composition thereof, a filter material of the post-filtering contains activated carbon, and the ozone sterilization and disinfection process is set between the pre-filtering and the post-filtering. The method can basically eliminate bromates produced by ozone treatment.
Description
Technical field
The present invention relates to the drink water purifying field, especially utilize the technology of ozone the tap water sterilization and purification.
Background technology
Utilize that ozone carries out that sterilization and disinfection is handled at tap water, just more and more used in bottled and Production of Barrel Purified Drinking Water and the home terminal device for purifying potable water.But in the time of ozone kill bacteria virus, but the also organic pollutant in the water of decomposition also has certain oxygenolysis to inorganics and heavy metal.But ozone is when being used for purification of water quality, if contain bromide in the water, ozone and bromide reaction can produce a certain amount of bromate.Bromate is identified as a kind of potential carcinogens, and bromate exceeds standard and can damage human body.If can not effectively remove the bromate of ozone generation, will influence ozone in the purification of water quality Application for Field.
Summary of the invention
When the efficient sterilization usefulness of utilizing ozone is carried out the drinking-water quality purification, reduce and eliminate harmful side product bromate content and become main purpose of the present invention.The invention provides a kind of filtration and ozone sterilization sterilization combination process flow process, using the ozone sterilization disinfectant to reduce the generation of bromate simultaneously and eliminating the bromate that produces.
Most of now tap water adopts chlorine or hypochlorous acid to carry out sterilization and disinfection and guarantees water conditioning, is easy to sneak into consanguinity bromide in the water.When utilizing ozone that tap water is carried out secondary treatment, bromide can change bromate into.One of method of eliminating bromate is to utilize gac to adsorb, but when containing chlorine in the water, can reduce the adsorption effect of gac to bromate.Therefore to reduce and eliminate the content that bromate that ozonize produces should reduce bromide in the water,, reduce the content of chlorine in the water again to reduce the generation of bromate, with reduce and elimination chlorine to the influence of charcoal absorption bromate.
The invention provides following purification of water quality flow process; At first tap water is carried out adsorption filtration with the fore filter that contains carbon leaching material, high purity copper zinc alloy (KDF) filtrate or gac and KDF combination filtrate, in removing water in the basic impurity, utilize gac to the adsorption of chlorine and bromide and KDF reduction decomposition effect to chlorine, chlorine and bromide in minimizing and the elimination water, carrying out ozone sterilization then disinfects, reducing the generation of bromate, with the post-filter that contains gac ozone water is carried out ozone in adsorption filtration and the water of decomposition more at last.Because the influence of chlorine is reduced in the front, gac is strengthened the adsorptive power of bromate, can fully remove the bromate in the water.
Embodiment
Tap water enters the fore filter that contains gac and KDF through water inlet pipe in the pipeline, through primary filter, charcoal absorption and (or) KDF handles, and reduces and eliminates the existing water tank of inflow place behind chlorine in the water and the bromide, finishes elementary adsorption filtration process; Start water circulating pump and ozonizer then, handle the water tank bottom water outlet and link to each other,, form the ozonization circulating treatment procedure by reflow tank behind the thorough mixing of mixing battery realization ozone and water with water circulating pump; After the ozone sterilization decontamination cycle finished, pump linked to each other with the post-filter that contains gac, made water in the processing water tank through the secondary filtration and the charcoal absorption of post-filter, and entered clear water tanks behind the ozone in the water of decomposition, finished whole water purification processes.
Claims (3)
1. ozone water-purifying treatment process that can reduce and eliminate bromate is characterized in that: the purification of water quality process is handled by preposition adsorption filtration, ozone sterilization decontamination cycle and rearmounted adsorption filtration is formed.
2. water purifying treating method according to claim 1 is characterized in that: preposition filtering filtrate contains gac, high purity copper zinc alloy (KDF) or both and contains, and rearmounted filtering filtrate contains gac.
3. water purifying treating method according to claim 1 is characterized in that: the ozone sterilization sterilizing process places between preposition filtration and rearmounted the filtration.
