Description
Technical field
The present invention relates to a kind of water treatment annex, more specifically, relate to a kind of metal ceramic filtration plate.
Background technology
Ceramic filter plate of the prior art is mostly sector structure, if the applying date is on October 8th, 2005, application number filter disclosed in the Chinese patent of 200520129104.9 comprises potsherd and is coated in the filtering coatings on potsherd surface, wherein the surface of potsherd is also provided with crisscross water storage passage, the cross sectional shape of this water storage passage is circular or oval, during filter work, water storage channel interior is evacuated, water infiltrate filtering coatings to be filtered enters water storage passage and namely completes filtration, with regard to arranging of water storage passage, water storage passage of the prior art is all arranged at ceramic wafer inside, and it is interlaced or be communicated with by common extraction channel between water storage passage, on the bottom surface or side of ceramic wafer, arrange one for drawing the conduction hole of filtered water simultaneously.But the filter of above shape and the deficiency of water storage passage existence are: 1, water storage passage radially distributes in fan-shaped screen plate, so more concentrated near its distribution of covering of the fan serrated end place, but very sparse away from water storage passage distribution during covering of the fan serrated end, this causes Partial filtration coating not play filtration, causes the waste of filter sheet material to a certain extent; 2, derive through conduction hole after the current in every bar water transport channel must converge, the water body through filtering can not be discharged rapidly, limit the filtered water total amount of ceramic filter plate within the unit interval; 3, the matrix at filter course and water storage passage place independently two parts often in filter, this makes production process operation lengthy and tedious, and this Split type structure also may in use be separated, thus allows filter lose efficacy.
Simultaneously, in existing ceramic wafer, water storage passage is nearly all oval or circular, with regard to the cross section of ceramic wafer, filter course thickness corresponding to the diverse location of water storage passage is different, this makes on the one hand to enter the water quality of water storage passage from different strain position can be different, on the other hand in the place that water storage passage is thicker with the interval in the external world, the filter efficiency of filter is lower, under larger pressure, just can realize the filtration to water, this also have impact on existing ceramic filter plate and gives full play to its filtering efficiency.
In addition, Modern sewage processing procedure is divided into tertiary treatment processes usually, wherein coagulation (physical treatment) will pass through the raw sewage of coarse rack after sewage pump promotes, through grid or sand filter, enter setting pot afterwards, then the sewage be separated through sand water is imported primary sedimentation pond; Two stage treatment then comprises allows the water outlet of first settling tank enter biological treating equipment, this stage has activated sludge process and biomembrance process usually, (wherein the reactor of activated sludge process has aeration tank, oxidation ditch etc., biomembrance process comprises biofilter, biological rotating disk, biological contact oxidation process and biological fluidized bed), the water outlet of biological treating equipment enters secondary sedimentation tank, and the water outlet of secondary settling tank is through sterilization discharge or enter tertiary treatment; Tertiary treatment then comprises and utilizes biological carbon and phosphorous removal method, coagulant sedimentation, sand filtration method, active carbon adsorption, the processing procedure of ion-exchange and electroosmose process, a mud part for secondary settling tank is back to primary sedimentation pond or biological treating equipment, a part enters sludge concentration tank, enter sludge digestion tank afterwards, after dehydration and drying equipment, mud is finally utilized.
Although effectively can be processed sewage by above-mentioned prior art, but the problem of the method is, above-mentioned each processing procedure needs to arrange corresponding treatment pond, and for extensive sewage disposal, such treatment pond takes up an area greatly, the land resource of more and more growing tension brings huge pressure, becomes the bottleneck of water treatment field gradually, but not having in the industry good method at present can solve the problem.
Summary of the invention
Object of the present invention, overcome the deficiencies in the prior art exactly, a kind of metal ceramic filtration plate is provided, in this metal ceramic filtration plate, be provided with the through hole through with the end face of filter, water body in through hole can be discharged in time, avoid it to be accumulated in the water flux of through hole internal influence filter.
In order to achieve the above object, following technical scheme is adopted:
