Abstract
The invention relates to a mechanical filtration device, and particularly relates to a bacteriostatic reverse osmosis security filter for sewage deep treatment. The bacteriostatic reverse osmosis security filter comprises an upper end cover, a lower end cover, a baffle plate arranged in parallel with the upper end cover, filter cores, a shell provided with a water inlet pipe and ultraviolet lamps, wherein the filter cores and ultraviolet lamps are arranged alternatively between the upper end cover and the baffle plate; the upper end cover is provided with a through hole; the bottom of the lower end cover is provided with a water outlet pipe; the shell is vertically arranged between the upper end cover and the lower end cover; the filter cores are arranged between the upper end cover and the baffle plate in a linear array; the ultraviolet lamps are arranged between the upper end cover and the baffle plate in a circumference array; and the baffle plate is disposed in the shell. The bacteriostatic reverse osmosis security filter takes full use of ultraviolet rays, greatly reduces dosages of an oxidizing bactericide and a reducing agent, reduces damages of the oxidizing bactericide to the reverse osmosis membrane assembly, and realizes harmless bacteriostatic treatment of municipal sewage.
Description
Technical field
The present invention relates to a kind of mechanical screening device, be specifically related to the antibacterial reverse osmosis cartridge filter of a kind of advanced treatment of wastewater.
Background technology
Along with China's shortage of water resources, water is seriously polluted, Ecology deterioration problem becomes increasingly conspicuous and the enforcement of strict water resources management system, and municipal effluent is substituted to the inevitable choice that clean water source has become industrial enterprise.At present, reverse osmosis system has become the core in city sewage deep treatment system, yet because municipal effluent has high microorganism and high organic feature, in the process of reverse-osmosis treated municipal effluent, tend to occur more serious microbial growth, cause reverse osmosis system dirty stifled, cannot make reverse osmosis continuous and steady operation.
Summary of the invention
It is stable, easy to operate and can effectively suppress the antibacterial reverse osmosis cartridge filter of advanced treatment of wastewater of microbial growth that technical problem to be solved by this invention is to provide a kind of operation.
For solving above technical problem, the present invention adopts following technical scheme: baffle plate, the filter core that the present invention includes upper end cover, lower end cover, be arranged in parallel with upper end cover, be provided with shell and UV-lamp into water;
Alternate filter core and the UV-lamp of being provided with between described upper end cover and baffle plate, described upper end cover is provided with through hole, and described lower end cover bottom is provided with rising pipe, and described shell is vertically set between upper end cover and lower end cover.Described filter core is linear array between upper end cover and baffle plate, and described UV-lamp is circle-shaped array between upper end cover and baffle plate, and described baffle plate is located in shell.The distance of described UV-lamp and filter core is 7cm or following, and the wire terminals of described UV-lamp is connected with extraneous power supply through through hole, and described water inlet pipe is communicated with extraneous sewage, and the model of described UV-lamp is Shanghai four-way 40W quartz burner.
Positively effect of the present invention is as follows: the ultraviolet ray that UV-lamp of the present invention is launched can effectively suppress microorganism and the bacterium in sewage, reduce municipal effluent to the dirty stifled risk of reverse osmosis system, extend the reverse osmosis cycle of operation, effectively reduce reverse osmosis cleaning frequency; Integrated setting of the present invention, simple in structure, can process in real time municipal effluent, simple to operation, improved fungistatic effect; The present invention makes full use of ultraviolet ray, has greatly reduced the dosage of oxidizing bactericide and reductive agent, has reduced the infringement of oxidizing bactericide to reverse-osmosis membrane element, has realized the innoxious antibacterial processing of municipal effluent.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is filter cartridge construction schematic diagram of the present invention;
In the drawings: 1 upper end cover, 1-1 through hole, 2 lower end covers, 3 filter cores, 4 UV-lamp, 5 rising pipes, 6 water inlet pipes, 7 shells, 8 baffle plates.
Embodiment
As shown in Figure 1, 2, baffle plate 8, the filter core 3, the shell 7 that is provided with water inlet pipe 6 and the UV-lamp 4 that the present invention includes upper end cover 1, lower end cover 2, be arranged in parallel with upper end cover 1; Alternate filter core 3 and the UV-lamp 4 of being provided with between described upper end cover 1 and baffle plate 8, described upper end cover 1 is provided with through hole 1-1, and described lower end cover 2 bottoms are provided with rising pipe 5, and described shell 7 is vertically set between upper end cover 1 and lower end cover 2.
Described filter core 3 is linear array between upper end cover 1 and baffle plate 8, and described UV-lamp 4 is circle-shaped array between upper end cover 1 and baffle plate 8, and described baffle plate 8 is located in shell 7.Described UV-lamp 4 is 7cm or following with the distance of filter core 3, and the wire terminals of described UV-lamp 4 is connected with extraneous power supply through through hole 1-1, and described water inlet pipe 6 is communicated with extraneous sewage, and the model of described UV-lamp 4 is Shanghai four-way 40W quartz burner.
Baffle plate 8 of the present invention is provided with aperture, and the sewage that enters shell 7 flows out from the filter core 3 after uviolizing, between inflow and lower end cover 2, forms in reservoir chamber, finally by rising pipe 5, flows out.
Use when of the present invention, adopt municipal effluent as feed water by reverse osmosis, reverse osmosis system is prepared to put into operation first 30 minutes, connects UV-lamp 4 power supplys, starts UV-lamp 4, and filter core 3 is carried out to prolonged exposure.
The layout of UV-lamp 4 of the present invention has guaranteed that the irradiated fraction of coverage of every filter core 3 reaches more than 95%, the distance of light source and filter core 3 is less than 7cm, reach the object of each filter core 3 outside surfaces (influent side) being carried out to uniform irradiation, the equipment of realizing synchronously killing microorganism in filter core 3 surfaces and water in service.
The above embodiment is only the preferred embodiments of the present invention, and is not the exhaustive of the feasible enforcement of the present invention.For persons skilled in the art, any apparent change of under the prerequisite that does not deviate from the principle of the invention and spirit, it having been done, within all should being contemplated as falling with claim protection domain of the present invention.
