Description
Technical field
The utility model relates to the technology that adopts the membrane filtration mode to carry out the water body purification processing, is specifically related to a kind of water body purification treating apparatus.
Background technology
Membrane filtration application development aspect Separation of Solid and Liquid in recent years is very fast, compares with conventional isolation technics, has efficient height, low, the no phase transformation of energy consumption, installs series of advantages such as simple, easy to operate.In filter process, liquid constantly sees through from fenestra, and solid particle then tunicle is held back, small quantities of particles stops up fenestra, causes membrane flux and selectivity to descend, therefore, remove the pollution in face and the fenestra, it is very important important step in filtering that controlling diaphragm pollutes in good time.It is comparatively complicated that filter membrane is changed the operation of cleaning specially, and cost is higher.
At present, adopt back-flushing technique that film is carried out inverse osmosis usually, get express developed, reach the purpose of removing contamination, correspondingly reduced the number of times of filter membrane being changed special cleaning.
Conventional recoiling device is to adorn the clean liquid of storage under dynamic action, make liquid at high speed pass through fenestra with the process opposite with filter process, pollution in film surface and the fenestra dashed take off, constantly drain simultaneously and carry pollution liquid secretly, though can play the effect of cleaning film like this, the liquid of carrying pollution in a large number secretly also is wasted.
The utility model content
The utility model provides a kind of water body purification treating apparatus, frequently filter membrane is carried out the problem of the water resource waste that the recoil process causes to solve prior art.
This water body purification treating apparatus comprises sewage inlet control device, filter element, filtration power set, recoiling device, water purification effluent control device and concentrated dirt discharger; Wherein sewage inlet control device, filter element, filtration power set, water purification effluent control device connect and compose the filtration path successively through pipeline, described concentrated dirt discharger is held back side with the solid of filter element and is communicated with, the filter membrane outer surface of the fluid jet nozzle alignment filter unit of recoiling device;
Wherein, the water inlet of recoiling device after filtration power set be connected with the delivery port of water purification effluent control device; Perhaps recoiling device is provided with recoil pump separately, also is provided with another pure water inlet of filter element between filter element and filtration power set, and this recoil pump water inlet that is provided with separately directly is connected with another pure water inlet of described filter element.
Above-mentioned recoiling device adopts and can set the spray site type mobile on the track or the recoil shower nozzle of line style jet, makes the recoil jet cover the filter membrane surface that needs backflush process.
The filter membrane component of above-mentioned filter element mainly is made up of microporous barrier and film supporting construction.
Above-mentioned sewage inlet control device and water purification effluent control device are electrically-controlled valve.
This water body purification treating apparatus also comprises the fluid level controller that send liquid level in the described filter membrane component in order to the detection change, and fluid level controller control signal output is electrically connected with recoiling device.
The using method of this water body purification treating apparatus may further comprise the steps:
(1) normal filtration work
Treatment sewage enters in the filter membrane component, filters power set work simultaneously, and the water purification that will obtain behind membrane filtration is taken away;
(2) suspend filtration, backflush process
When membrane flux significantly reduced, the treatment sewage time-out entered filter membrane component; After water level is reduced to designated water level in the filter membrane component (chamber that is formed by filter membrane), filter power set and continue to draw water, and adjust and filter the trend of extracting the back water purification out as the recoil power set, it is used water purification as recoil, filter membrane is recoiled;
Perhaps when membrane flux significantly reduced, the treatment sewage time-out entered filter membrane component; After water level is reduced to designated water level in the filter membrane component, filter power set and quit work, the recoil dedicated pump recoils to filter membrane by extracting water purification in the filter membrane component out;
(3) recoil sewage concentrates
In the recoil process, the solid suspension that recoil forms in the filter membrane component concentrates by membrane retention under the deadweight effect, forms the dirty liquid of recoil and leaches the water purification that can directly utilize again; If this moment, the filter membrane membrane flux did not recover yet, recycle then that the described recoil of several times step (2), step (3) are described holds back concentratedly, recover membrane flux until filter membrane; Stop recoil, after the solid suspension that forms of waiting to recoil concentrates, discharge the dirty liquid of the recoil of holding back after concentrating;
Perhaps in the recoil process, the solid suspension of recoil formation in the filter membrane component is led to the recoil sewage enrichment facility of other setting, solid suspension is held back concentrated (filter medium can adopt forms such as film, sand, diatomite) by the filter medium in the enrichment facility under the deadweight effect in recoil sewage enrichment facility, forms to concentrate deposit dirt and leach the water purification that can directly utilize again; Filter membrane until described filter membrane component recovers membrane flux; Stop recoil, discharge then in recoil sewage enrichment facility and hold back the concentrated concentrated deposit dirt that obtains;
(4) change step (1) over to and carry out normal filtration work.
Above-mentioned recoil is to filter membrane jet surface point type jet or line style jet, is setting the mobile recoil of finishing the filter membrane all surfaces on the track by the recoil shower nozzle.
The utlity model has following advantage:
Utilize filter to hold back the work sewage that will recoil and concentrate the back discharging, therefore more conventional membrane filtration system back purge system reduces the backwashing water discharge capacity greatly.
