Abstract
The utility model relates to a multilayer dynamic film waste water purifying device, which is mainly composed of a bed body, a water inlet port, a water outlet conduit, a water-distributing plate, an aeration conduit, and a multilayer biofilm. Non-woven fabrics with different pore sizes are used as a film base material, and fixed on two or more layered frame constructed by according to the sequence from non-woven fabric with small pore size to non-woven fabric with large pore size to form two or more successively embedded sealed cavities, and the waste water is subjected to multilayer purification by the biofilm and discharged from the water outlet conduit in the inner cavity of dust film component. The utility model has the advantages of simple structure, convenient operation, large film-formation surface area, high microorganism content, and stable treatment performance.
Description
Technical field
The utility model relates to a kind of device that utilizes the non-woven biological film to purify waste water, specifically a kind of multilayer Dynamic Membrane effluent treatment plant.
Background technology
The Dynamic Membrane bed is to grow up on the basis of membrane bioreactor, and it adopts wide-aperture nethike embrane to replace traditional microfiltration membrane, relies on the Dynamic Membrane of online formation in the operational process to realize damming to pollutent.Compare advantage such as the cleaning of Dynamic Membrane and regeneration are very easy to, and it is low to have the membrane module cost, and energy consumption is little, and effluent quality is good, and effluent flux is big with the non-Dynamic Membrane of same apertures.But there is the leakage of mud in Dynamic Membrane in forming process, causes initial water quality not up to standard, and membrane module is easy to stop up often flushing repeatedly.
Summary of the invention
The utility model remedies the deficiencies in the prior art, provides a kind of membrane module be difficult for to stop up, the biofilm surface-area is big, content of microorganisms is high, effluent quality is limpid; Non-woven fabrics has the multilayer Dynamic Membrane effluent treatment plant of unique aperture space structure, strainability height and long service life.
The utility model adopts following technical proposals to realize:
Multilayer Dynamic Membrane effluent treatment plant, comprise a body, water-in, water distribution board, aerated conduit, multistory frame membrane module, water output duct, mud discharging mouth, baffle plate, it is characterized in that the multistory frame membrane module is to prop a spatial multistory frame with stainless steel or aluminium alloy, the non-woven membrane base material in fixing different apertures around framework, non-woven fabrics aperture on the internal layer framework is less than the non-woven fabrics aperture on the outer framework, constitute two or more nested enclosed cavities, a plurality of membrane modules are fixed on the slot of a body, it is contacted with active sludge; Water-in one side of bed body is provided with water distribution board and current baffle plate, and is provided with aerated conduit at the bottom position of bed body, and the opposite side bottom of bed body is provided with mud discharging mouth; Water output duct connects the inner chamber of multistory frame membrane module.
The utility model is a film base material with the non-woven fabrics in different apertures, by aperture order from small to large it is nested into three layers from inside to outside, and pollutent is removed by the size layering.When this device operation, sewage is entered by water-in, enters reaction zone behind the water distribution board water distribution uniformity, cross-flow passes under the effect of air-flow and baffle plate, microorganism breeds in a large number, and its meta-bolites forms one deck xanthan gel layer together with the very fast surface at membrane module of solid particulate.When sewage passes through biological membrane assembly, macrobead suspended substance is wherein stopped by the microbial film of outer larger aperture, subparticle and deliquescent macromole are filtered by the small-bore Dynamic Membrane of internal layer, and sewage is progressively purified, and flows out the water output duct in the membrane module inner chamber at last.Mud can be discharged from sludge discharging port.
This utility model has the following advantages: membrane module is difficult for stopping up, the volume load height, and treatment effect is stable; The biofilm surface-area is big, the content of microorganisms height, and effluent quality is limpid; Non-woven fabrics has unique aperture space structure, strainability height, and long service life; Simple in structure, operation, operation are conveniently.

Embodiment:
As shown in Figure 1: this device is made up of bed body 1, aerator 4, multistory frame membrane module 5.Wherein, multistory frame membrane module 5 is to prop a spatial multistory frame with stainless steel or aluminium alloy, the non-woven membrane base material in fixing different apertures around framework, non-woven fabrics aperture on the internal layer framework is less than the non-woven fabrics aperture on the outer framework, constitute two or more nested enclosed cavities, the cavity of its innermost layer links to each other with the water outlet flexible conduit.
During this device operation, sewage is entered by water-in 2, behind water distribution board 3 water distribution uniformities, enter reaction zone, cross-flow passes under the effect of air-flow and baffle plate 8, and and the abundant mixing of active sludge, microorganism breeds in a large number, and its meta-bolites forms the microbial film that one deck xanthan gel layer is formed together with the very fast meeting of solid particulate on the surface of multistory frame membrane module 5.When sewage passes through multistory frame membrane module 5, macrobead suspended substance is wherein stopped by the wide-aperture microbial film of skin, subparticle and deliquescent macromole are filtered under the effect of internal layer small-bore Dynamic Membrane successively, and organism is by Dynamic Membrane absorption degradation successively, and sewage is progressively purified.At last, sewage is filtered the innermost layer cavity into multistory frame membrane module 5, under the driving power of reaction bed liquid level and thrust-augmenting nozzle difference of altitude, flows out from water output duct 6 automatically.Behind the long-play, the mud of accumulation can be discharged by shore pipe 7.
