Description
Technical field
The utility model relates to feedwater/sewage disposal technology, relates 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.
