Description
Technical field
The utility model relates to a kind of water treatment device, especially relates to a kind of uv ozone combined disinfection device that is used for the water reuse.
Background technology
Along with the worsening shortages of water resources, the regeneration of sewage is also more and more, and the water quality of middle water also receives increasing concern.Though the conventional processing process of middle water can be removed the part mikrobe, the absolute content of mikrobe is very considerable in the water, and has the possibility of pathogenic bacteria.Therefore, sewage disinfection before reuse is significant, and disinfection has also become an indispensable link in the reuse water processing." architectural intermediate water design specifications " (GB50336-2002) in clearly the regulation: " middle water treatment must be provided with disinfection apparatus ", this has also reflected the importance of middle water sterilization.
Chlorine disinfectant is mainly adopted in water sterilization at present domestic.In many water sterilization technology, because that the chlorine disinfectant technology possesses skills is ripe, experienced, use history remote, therefore, chlorine disinfectant is the most widely used a kind of sterilizing method of China.But this sterilization method has certain requirement to the potential of hydrogen of water, and the water body after chlorine treatment can produce some chlorination organism risky to HUMAN HEALTH, like haloform, halogen acetic acid etc.In addition, chlorine disinfectant preparation of medicaments, transportation, the process of storing, adding are complicated, and have potential safety hazard.Therefore, select different disinfection way (like uv sterilisation, ozonization etc.) significant according to different water quality situation and processing requirements.
Uv sterilisation has technically need not add advantages such as chemical agent, germ-killing efficiency is high, speed is fast; At economic aspect, the expense of each side such as its civil engineering, operation, maintenance is all lacked than chlorine disinfectant.But uv sterilisation is higher to requirements in water quality, and does not have the germicidal action that continues.Ozone is a kind of colourless, gas that slight smell is arranged, has strong oxidizing property, and extremely strong sterilization, biocidal efficacies are arranged, and the DBPs that produces is few, is called as " green disinfectant ", is widely used in the sterilization of tap water, swimming pool etc.The ozonization sterilization effect is good, and disinfection efficiency can reach 15 times of general chlorine disinfectant, and has certain lasting sterilizing ability, and non-secondary pollution also has the effect of decolouring, taste removal concurrently.But the working cost of ozonization is slightly higher than uv sterilisation, and the dosage of ozone is difficult to accurate control.So, consider the mode of ultraviolet, ozone combined disinfection, reach the effective disinfection of the middle water of different quality, and the purpose of stable sterilization effect.At present, more existing uv ozone disinfection technology of uniting use applies to tableware and domestic running water disinfectant instance.
Summary of the invention

Described dividing plate is provided with four roads, and water tank is divided into five tanks, and described ultraviolet lamp tube group is made up of the ultraviolet lamp tube that is arranged on each sink top.
Described reactor drum is a cylindrical reactor, and it is shaped as cylindrical, is provided with column sealed sleeve pipe at its top, and described column sealed telescopic upper end is provided with the ozone relief outlet.
Flow in the described water inlet pipe is 20～40L/min.
Compared with prior art, the utlity model has following advantage:
1) the uv sterilisation water tank adopts barrier type, has increased the flow velocity of water body in the case and has avoided occurring in the case slough; The ultraviolet lamp tube group can not produce the fluorescent tube scale formation in the case on the water surface, and chamber interior wall is done polished finish, has increased the yield of radiation of uv lamp; According to flow and the water quality situation of water inlet, the unlatching quantity that can regulate ultraviolet lamp tube, save energy to greatest extent under the prerequisite of assurance sterilisation effect; Uv sterilisation case simple in structure, the installation of equipment, maintenance and management are convenient.
2) ozone and water mix through venturi mixer, have improved the mixed effect of ozone and water, have increased the concentration of ozone in water.
3) contact device of ozone and water adopts cylindrical reactor, and water (flow) direction adopts upward flow.At reactor bottom; Pressure is relatively large, has increased the solubleness of ozone in water, and the ozone of overflowing is consistent with water (flow) direction; After being pooled to the middle and upper part of reactor drum; Because phase concentrations increases and to cause part ozone to dissolve again, makes that the ozone concn of reactor drum middle and upper part is also higher, so not only improved the utilization ratio of ozone but also ensured the water quality of water outlet.
4) sterilizing process of whole device adopts the mode that ultraviolet and ozone combine, and has the independent ultraviolet and the disinfecting reactor of ozone, has given full play to the fast efficient and lasting germ-resistant advantage of ozonization of uv sterilisation.For water quality situation preferably, can suitably improve the flow of water inlet, and, after suitably reducing flooding velocity, also can guarantee the good sterilization effect for the relatively poor situation of water quality.
