Description
Technical field
The invention belongs to field of membrane bioreactor technology, particularly a kind of integrated tubular dynamic membrane bioreactor.
Background technology
The treatment system that membrane bioreactor is made up of membrane separation assemblies and traditional bio-reactor.Adopt membrane module to replace traditional second pond in the membrane bioreactor, the high reactivity sludge concentration in can the realization response device, thus waste water is effectively handled.Integral type film biological reactor places membrane module in the bio-reactor and disposes of sewage.Compare with detachable membrane bioreactor, the biological device operation of integral type film power charge is low, and compact equipment, occupation of land are lacked.
There is the high and film pollution problems of film cost in membrane bioreactor in applying.In order to overcome the above problems, carried out many-sided research both at home and abroad, Dynamic membrane is wherein more characteristic and a kind of preferably method of effect.(Qiao Sen, Zhang Hanmin, Zhang Xingwen, Yang Fenglin. the progress of Dynamic membrane [J]. Chinese water supply and drainage, 2003,19 (12): 29-31.) Dynamic Membrane is meant by precoating paint or active sludge and is also referred to as secondary film at the new film that the film surface forms.(Lee J, Ahn W Y, Lee C H.Comparison of the filtration characteristics between attached andsuspended growth microorganisms in submerged membrane bioreactor[J] .Wat Res, 2001,35 (10): 2435-2445) therefore, in membrane bioreactor, can adopt the bigger fiber establishment tube material in aperture to replace mould material, in the process of filter activity mud mixed liquid, initiatively form one deck microbial film, carry out solid-liquid separation.This kind membrane bioreactor has following advantage: 1, the fiber of Dynamic Membrane establishment tubing is cheap and easy to get, can reduce the cost of membrane bioreactor significantly; 2, the filtration resistance of Dynamic Membrane is very little, and flux is big; 3, the pollution of Dynamic Membrane is controlled easily, adopts the below aeration can recover the flux of Dynamic Membrane fully.Therefore, bioreactor of dynamic membrane has good application prospects for the not high waste water of treat effluent water quality requirement.(model is refined, Huang Xia, and Wen Xianghua is in grinding. and Dynamic Membrane-bio-reactor is to municipal sewage treatment [J]. environmental science, 2002,23 (6): 51-56) but also fewer to the research of bioreactor of dynamic membrane now.The kit form forms that adopt similar and flat sheet membrane more.It is rare to adopt the tubular type material of fiber establishment to make the research of membrane module.
Summary of the invention:
The objective of the invention is to advantage and dynamic film formed principle, invented a kind of integrated tubular dynamic membrane bioreactor in conjunction with above integral type film biological reactor.A kind of bioreactor of dynamic membrane that adopts the new membrane kit form is provided.
Integrated tubular dynamic membrane bioreactor provided by the invention mainly is made up of bio-reactor, aeration tube, under meter, suction pump etc.Described bio-reactor is the bioreactor of dynamic membrane biochemical reaction zone, and high activated sludge concentration is arranged, in assembly, aeration tube, the liquidometer that the tubular type fiber establishment tubing that will form Dynamic Membrane is made is housed.Assembly is that water outlet is extracted out by suction pump from the upper end header by many in parallel formation of hollow tubular type fiber establishment tubing, and selected tubular type fiber establishment tubing need have certain supporting capacity.In the process of tubular type fiber establishment tubing filter activity mud, can form the dynamic biological film of forming by gel coat and sludge blanket, mainly play the effect of solid-liquid separation in this layer microbial film treating processes afterwards, to the performance degraded of the organism in the waste water, transformation mainly is active sludge in the biochemical reactor.Aeration tube is a distance aeration below assembly, and suitable tolerance can provide microorganism growth required oxygen, can wash fiber establishment tube surfaces during atm number, prevents that the flux that degree of depth pollution causes from descending.
The working method of integrated tubular dynamic membrane bioreactor of the present invention is: sanitary sewage or trade effluent enter bio-reactor (2) by water inlet pipe (1) after pre-treatment, fully contact with the active sludge in the reactor, pollutants in waste water obtains removing under the absorption of microorganism, oxygenolysis, sends out to answer that required oxygen is provided by aeration tube (8) in the device.Water outlet is extracted out by suction pump under the filtration of tubular dynamic membrane.
Integrated tubular dynamic membrane bioreactor of the present invention has following feature:
1, integrated tubular dynamic membrane bioreactor is made up of bio-reactor, dynamic film component, aeration tube, under meter, liquidometer, blower fan etc.It is characterized in that dynamic film component replaces expensive mould material in the conventional film bio-reactor with cheap fiber establishment tubular type material, can save the cost of membrane bioreactor in applying greatly.
2, its bio-reactor of integrated tubular dynamic membrane bioreactor is the reactor of activated sludge process.
3, the fiber of dynamic film component establishment tubular type material employing diameter is the chemical synthetic fiber material of 1-10mm.Dynamic film component fiber establishment tubular type material length is 0.2m-5m, and the fibre pipe of dynamic film component vertically places in the biochemical reaction tank.Dynamic film component is placed downwards from biological reactor liquid level, and the header top is submerged in 0-500mm place under the bio-reactor low-water level just on the dynamic film component.
4, adopt cheap chemical synthetic fiber material to replace expensive mould material in the conventional film bio-reactor, saved the cost during membrane bioreactor is applied greatly.
5, the dynamic membrane filtering resistance that forms on the tubular type fiber establishment tubing is little, and flux height, and easy cleaning can solve the membrane pollution problem of conventional film bio-reactor effectively.
6, fiber is worked out the dynamic film component that tubing makes and placed in the biochemical reaction tank, working cost is low, occupation of land is few.
