Description
Technical field
The present invention relates to the filtration treatment device of water, refer in particular to the tandem double-stage filtering device of marking engineerings such as transformation is carried in Drinking Water processing, water for industrial use processing, middle water Treatment for Reuse and urban water supply facility upgrading transformation and sewage treatment plant.
Background technology
In existing filtering technique, generally adopt in-depth filtration, be that the particulate filter of representative is used the earliest with the quartz sand particle filtrate, also be the most widely.In the filter in early days, adopt single-stage quartz sand particle filter tank layer, facilitated the notion of " desirable filtering layer " to propose owing to " hydraulic classiciation " deficiency occurs.So-called " desirable filtering layer " is meant in filtering layer, along the filtering layer of filtering direction void size by the descending distribution of successively decreasing.The mode of " desirable filtering layer " of pressing is filtered the shortcoming that can overcome the filtering layer loss of flood peak quick rising in top when filtering effectively, is able to hold back thereby make more suspension have an opportunity to get into darker filtering layer.So, filtering at the end, the usefulness of whole filtering layer all can be given full play to.The notion of " desirable filtering layer " is that researchers update and theoretical foundation of developing filtrate, filtering layer and filtering technique.Based on the notion of " desirable filtering layer ", the researcher has developed double-layer filter material in the 1950's; 60 have developed three-layer filter to the seventies; Be that the researcher of representative has developed homogeneous filtering material again the eighties with France.Though the granule filter material backwash effect is good, filtering layer mixes, and therefore, the particle diameter that is used for bilayer, three layers and homogeneous filtering material is restricted.Indexs such as the holding filth capacity of its filter material layer, filtering velocity, efficient are the progress of not making a breakthrough property all.Thereby the researcher begins to explore the filter material of the material beyond the granule filter material, to promote the development of in-depth filtration technology.
Replacing granule filter material with whippy fiber filtering, is developing a kind of new thinking of filtering technique and trial.Fibrous material is with its higher mechanical strength, and good chemical stability and stronger adsorption capacity have the ideal conditions as filtering material; And the body that it had light (density is little), the footpath is thin, matter is gentle characteristics then make the fiber filtering layer not only have huge specific area and higher porosity, but also can under the effect of waterpower or mechanical compress, form the filter type of " desirable filtering layer ".1981, the outstanding researcher of Ni Qika company of Japan processed short fiber with long fibre, replaces the particle fiber.Make and filter that effluent quality is good, filtering velocity is high, filter cycle is long, holding filth capacity is big, relatively meets the distribution of " desirable filtering layer ".Environmental project research institute of domestic Tsing-Hua University has carried out systematic research to the fiber filtering filtering technique from nineteen eighty-three, has developed the comet type fiber filtering.The effluent quality of comet type fiber filtering, filter bed maturity period, holding filth capacity and filter cycle etc. all make moderate progress, but because filtering layer is too thick, and there is the dead band in some areas, problem such as have backwash tolerance, the water yield is big, and backwash is inhomogeneous.
In sum, in filter, use granule filter material and fiber filtering respectively to have superiority, but the part that also comes with some shortcomings.Not high like the granule filter material strainability, but backwash effect is good; And the fiber filtering strainability is high, but backwash effect is not good.
Immediate documents does, number of patent application 01204007 discloses a kind of bitubular low-pressure filter, is applicable to raw water filtration and the water treatment of swimming pool in the water supply system, is made up of two identical filter elements, and interconnects through outlet pipe.Each filter element is made up of cartridge filter, reversal valve, flushing valve and centrifugal pump again.Cartridge filter is a cylindrical tube, and there is the end lower end, and there is lid the upper end, is provided with water distributor, water distributing plate, filtrate, grid, collector pipe in the tube.During filtration, reversal valve makes centrifugal pump and filter realize rational Match.But this device still can not reach the good purpose of strainability height and backwash effect.
Summary of the invention
The present invention is intended to solve the problem that above-mentioned filter exists in the engineering practical application, provides a kind of strainability height and backwash effect good couplet formula double-stage filtering device.
In order to reach above purpose, technical scheme provided by the invention is:
A kind of tandem double-stage filtering device; Be made up of first order filter element and second level filter element series connection connection, first order filter element and second level filter element include the body construction of being made up of bottom enclosure end socket, middle housing cylinder and top enclosure end socket; It is characterized in that the water side of said first order filter element water inlet pipe is provided with inlet damper a; Inlet damper a below is gathering ground a, and a below in gathering ground is provided with quartz sand particle filter material layer, supporting layer successively, has the filter plate a of short-handled filter head a, supports short tube a and supports base plate a; Bottom enclosure end socket below is connected with first order outlet pipe; First order outlet pipe is communicated with an end of the second level water inlet pipe of second level filter element; The other end of second level water inlet pipe is provided with inlet damper b, and the below of this inlet damper b is gathering ground b, and b below in gathering ground is provided with filtrate catching sheet, diffusing heap formula short fiber filter material layer successively, has the filter plate b of short-handled filter head b, supports short tube b and support base plate b; The bottom enclosure end socket below of second level filter element is connected with filter back water pipe.
The top of said body construction middle housing cylinder all preferably is provided with inspection manhole.
The effect of said inlet damper a and inlet damper b is to make aqueous dispersion even.
Device of the present invention is mainly used in Drinking Water, the advanced treating of water for industrial use and dirty waste water.
The invention has the beneficial effects as follows: device of the present invention combines with the high characteristic of fiber filtering strainability the granule filter material backwash effect is good; Amplify two kinds of filtrates advantage separately; Alleviate the surface filtration phenomenon as far as possible, accomplish that " the desirable filtering layer " of real meaning filters.
In the twin-stage high-efficiency filtration systems, the first order adopts the quartz sand particle filtrate, can hold back the big molecular impurity of removing in the water and play coarse filtration; The second level heap formula short fiber filtrate that adopt to loose because specific area is big, can be held back and remove that tiny a small amount of residual impurity plays the secondary filter effect in the water, thereby guarantee effluent quality.
