Description
Technical field
The utility model relates to a kind of water treatment device, particularly a kind of reused water processing device.
Background technology
Along with the worsening shortages of water resources, the reclaimed water reuse technology has obtained people's extensive attention gradually.Especially in the very short Beijing of water resources, from the needs of longterm planning and environmental protection Olympic Games landscape water in 2008, reclaimed water reuse is also to the utmost to be urgent.Now, be applied in the various technology of reused water processing based on biochemical, coagulation dosing precipitation and membrane bioreactor.Its biochemical method is exactly to utilize microorganism to decompose organism in the sewage, obviously, microorganism itself is exactly an organism, and the water after biochemical method is handled still can not reach the reuse standard that contacts with human body, mainly is that colourity, turbidity, peculiar smell, ammonia nitrogen and oxygen-consumption exceed standard.Water after biochemical method is handled is difficult for using traditional technology and carries out the deep purifying processing once more.
There are some unreasonable factors in existing membrane bioreactor itself, has influenced its work-ing life and decontamination effect improving greatly.Membrane method treating process comprises micro-filtration, ultrafiltration (UF), nanofiltration (NF), reverse osmosis (RO) and Membrane Bioreactor for Wastewater Treatment technology.The micro-filtration processing accuracy is not high, can only select for use the reverse osmosis system producing water ratio of film imported not high as the pretreatment unit of ultrafiltration, and antifouling property is relatively poor, is difficult to use in extensive sewage disposal and reclaimed water reuse.Existing membrane bioreactor mostly is curtain type film assembly, and its assembly top is that the tubular fibre curtain type membrane is immersed in the biochemistry pool for the sealing hydroecium, and aeration is swung the hollow fiber ultrafiltration moisture film at the bottom of the pond in the liquid of pond.By the generation " negative pressure " of bleeding, thereby finish water filtration, with the purification of negative-pressure operation realization to sewage, its principle of work characteristic is very easily polluted and biological degradation curtain type film assembly, this method is feasible in some small-sized simulated experiments, but the neat root fracture of film then appears in the heavy construction, can't promote extensive application, existing membrane bioreactor adopts backwash technique, pour water purification from the import of hollow fiber ultrafiltration moisture film inner core, go out by hollow fiber ultrafiltration moisture film sidewall, dirt is rinsed well from the hollow fiber ultrafiltration moisture film.The shortcoming of this technology is that the filter opening of hollow fiber ultrafiltration moisture film stops up easily, and work-ing life is short, and flush efficiency is low, so can not be referred to as the choosing of ideal.
The utility model content
The utility model provides a kind of malleation biochemical water film filtering device, solve membrane bioreactor work-ing life short, antifouling property is relatively poor, purification efficiency is low, the problem of readily biodegradable.
The technical scheme of the biochemical water film filtering device of the utility model malleation: comprise the hollow fiber ultrafiltration moisture film in shell and the shell, row's concentrated water spout is communicated with shell, and water outlet is communicated with the outlet of hollow fiber ultrafiltration moisture film inner core, it is characterized in that:
A, shell are a tank body that loam cake is arranged, and last tops is connected with water outlet, and tank base is connected with row's concentrated water spout, are fixed with ring flange between loam cake and the tank body, form water purifying chamber above the ring flange and between the loam cake;
The top of b, each intrafascicular empty ultrafiltration moisture film places in package shell and the assembly loam cake, and the outlet of the inner core of hollow fiber ultrafiltration moisture film is communicated with water purifying chamber, forms hollow malleation ultrafiltration moisture film assembly;
C, at least one hollow malleation ultrafiltration moisture film assembly are suspended under the ring flange, wear ring flange in the outlet of the inner core of hollow malleation ultrafiltration moisture film assembly, fix with flangeseal around it;
D, be equipped with water distributor below hollow fiber ultrafiltration moisture film assembly, water distributor is formed by connecting by being communicated with the outer horizontal person in charge of tank body, athwartship leg and vertical floral tube, having water spray flower hole on its vertical floral tube, and extending upwardly to hollow malleation ultrafiltration moisture film assembly side.
For flange is connected, the centre is equipped with sealing-ring between above-mentioned loam cake and the tank body.
The above-mentioned horizontal person in charge, athwartship leg and vertical floral tube are connected by threeway, four-way or bend pipe tools each other.
Top cover is stamped on above-mentioned vertical floral tube top.
The above-mentioned water outlet of going up tops is connected with the timer switch valve.
Row's concentrated water spout of above-mentioned tank base is connected with the pressure sensing valve.
Beneficial effect: the biochemical water film filtering device of the utility model malleation is that filter membrane component curtain formula is arranged that changing disc type into arranges, filter membrane component is selected hollow malleation ultrafiltration moisture film assembly, be placed in the sealed can, the tubular type water distributor is arranged in the tank body, by water-aspirator pressure second pond water is injected tank body, after hollow malleation ultrafiltration moisture film assembly filters, export in the water purifying chamber that drains into more than the tank flange dish by inner core, again through timer switch valve input water supply line.Sewage second pond supernatant liquor, after this reactor filtered, water quality can reach the reuse water service requirements.
When the hollow membrane biochemical reactor need wash, the utility model is a positive pressure wash, need not back flushing, when timer sends flush signal, automatically close with the timer switch valve that tank body top water outlet is connected, wash-down water laterally is responsible for from water distributor and is entered, and makes supercharging in the hollow membrane biochemical reactor tank body, when pressure tank reaches 3-5 kilogram/cm
2The time, the pressure transmitter command pressure sensing valve (heavy caliber) of tank base is opened, water is discharged at a high speed from arranging concentrated water spout under pressure in jar, this moment, a jar interior hollow malleation ultrafiltration moisture film assembly formed pencil under flow action, and be rinsed clean, since arrange the concentrated water spout footpath greater than one times of water-in, when the jar internal pressure is lower than 0.5kg, below pressure sensing valve locking.
The utility model adopts positive press filtration, flushing, and is simple in structure, easy to operate, the purification efficiency height, and the water treatment comprehensive cost reduces, and filter membrane prolongs work-ing life.Solved membrane bioreactor work-ing life short, antifouling property is relatively poor, purification efficiency is low, the problem of readily biodegradable.Can be used for the municipal water use, the construction project water, irrigation water, landscape water and car washing water are if connecting tube advances building and can do flushing supply; If after connection nanofiltration purifier purified again, water quality reached drinking water standard.In the pollution-free and low region of hardness, can not add the biological bacteria direct filtration, substitute traditional tap water water preparation process, save a large amount of soils and flocculation medicament, guarantee water quality, reduce water producing cost.
