Description
Technical field
The present invention relates to feedwater/sewage disposal technology, relate in particular to a kind of multi-pipe internal pressure formula mechanical circulation forced cross flow solid-liquid separation dynamic membrane system and device that reduces the waterpower dead angle.
Background technology
Enter 21 century, the water treatment application of membrane separation technology more and more widely.The Dynamic Membrane isolation technics, because its counter investment cost is low, film pollutes control easily, low power consumption and other advantages becomes when cephacoria research focus.
Dynamic Membrane (Dynamic membrane) can be called secondary film (second membrane) again, is meant the new film that forms in micro-filtration membrane, milipore filter or large aperture supporting body surface by precoating paint or activated sludge.The formation of Dynamic Membrane can slow down micro-filtration membrane, the ultrafiltration face stops up (Block) and film pollutes (Fouling), or improves the interception capacity of macropore supporter.Dynamic Membrane generally is divided into two types of spontaneous film and pre-coating films: spontaneous film only needs to rely on material in the separated mixture, and pre-coating film then needs to add one or more specific components materials in the water that separates, and forms by direct or precoating circulation.
The material and the kit form that can be used as dynamic membrane support body are a lot, for example, with organic material cellulose acetate, polyacrylonitrile (PAN), Kynoar (PVDF), polyvinyl chloride (PVC), sintering polyethylene (PE), polysulfones (PS) etc., and micro-filtration membrane or the milipore filter made such as inorganic material sintered ceramic, sintering metal particulate filter stick, and macropore nylon wire, stainless (steel) wire or nonwoven cloth material, all can be used as the supporter of Dynamic Membrane.
Generally, the backing material that is formed by sintering such as plastics, pottery, metals is called porous material, and backing materials such as stainless (steel) wire, nylon wire, polythene net and industrial filter cloth, nonwoven are called the large aperture net.Porous material and large aperture net are played a supporting role to Dynamic Membrane, so be called the supporter of Dynamic Membrane.
At feedwater/sewage/liquor industry, often there is a large amount of solid particle polluters in feedwater, sewage or the wine brewing, generally solid particle polluter is separated by Separation of Solid and Liquid.In addition,, need in water, add tiny solid particulate matter at sewage/give in the water treatment procedure, as activated sludge, Powdered Activated Carbon, diatomite etc., the organic substance in these particle mass-energy adsorbed water or on the superficial growth bacterium, and play biochemical action.These particulate matters are finished after the effect that purifies water, and need again it is separated from water, carry out Separation of Solid and Liquid.Generally, the dynamic membrane support body that is applied to Separation of Solid and Liquid needs following characteristics: material has certain intensity, can not subside after Dynamic Membrane forms; Dynamic Membrane comes off in the flushing engineering easily; Supporter is durable in use, can not be corroded and mechanical failure; Cost is low.
The aperture of porous material and the particulate matter particle diameter in the water are basic identical, so these intergranular slits are exactly the passage that liquid flows into.These passages are very tortuous, though can guarantee the precision of filtering, stopped up by tiny particulate matter easily; And the also easy breed bacteria in these slits, the thick substances of bacterium surface also can block the slit.The filter membrane that organic matter is made, milipore filter by the particulate matter damage and failure, influence filtering accuracy easily.In addition, these slits are in the inside of porous material, and method such as be not easy to use backwash, wash, scrub solves the problem that the slit is blocked, and therefore flux sharply descends, and it is not high to reuse efficient.And the large aperture net its aperture generally be tens times of particulate matter to hundred times.Particulate matter in the water can produce arch formation, and be held back by the large aperture net in surperficial by it, does not subside, and progressively thickens, and forms cake layer (filter membrane).Current are then by the slit flow filter cake layer between the particulate matter that forms cake layer, and by the large aperture net, particulate matter is trapped.This process is very similar to the filter process of porous material, and filtering accuracy depends on the size of particulate matter particle diameter.When flux reduces to a certain degree, just can carry out backwash, wash and scrub.Cake layer is easy to come off from the large aperture net surface.Pass through the precoating particulate matter again at the large aperture net surface, form cake layer, can begin filter process next time again.Cake layer also is a Dynamic Membrane.Therefore, according to above-mentioned requirements, the large aperture net more is better than the Dynamic Membrane backing material of porous material as Separation of Solid and Liquid.
