Description
Technical field
The present invention relates to a kind of biomembrane draining treament system of innovation, formed by " bacteria bed district " and " divided thin film abscission zone ".
Background technology
(membrane bioreactor MBR) is applied to two stage biological and handles film usually, to remove COD, suspended solids (SS) and nitrogen-containing pollutant etc. from bioreactor technology.Because have the characteristic of biological treatment and membrane filtration, its water quality treatment can reach the effect near tertiary treatment, therefore also be fit to as the waste water recycling pretreatment unit.At present the more sophisticated MBR technology of development mainly belongs to solid-liquid separating type (solid-liquidseparation type), and it utilizes ultra-filtration (UF) or micro-filtration (MF) film to separate concentrated biological mud usually, to obtain the good flowing water water quality that goes out.
Because water flux density (flux, the m of unit of thin-film module
3/ m
2.day) be one of MBR technology most important control parameters, its hydraulic detention time (HRT), volume load, thin-film module pressure with MBR is relevant, and relate to and building and running cost, and the factor that influences flux is exactly a SS concentration except that water quality treatment and SS character.Though the manageable relatively amount of pollutant of SS concentration height is also higher, sludge concentration Gao Yihui causes the reduction of MBR flux and increasing of working pressure.
This case applicant announces No. 593167 and discloses a kind of water treatment method that carries out from bio-reactor in film in Taiwan, this reactor comprises a groove that includes the microorganism mixed solution; A plurality of porous carriers in this mixed solution; And a filtration module that is immersed in this mixed solution, it has one and penetrates side and this mixed solution and only see through this filtration module and this and penetrate side and be fluid communication.This method comprises an influent stream water is imported mixed solution in this groove; One negative pressure source is applied to this penetrates side, make liquid in this groove see through this filtration module and penetrate effluent from this and go out this groove; And these a plurality of porous carriers are contacted with this filtration module by mode to this mixed solution aeration, so reduce the incrustation on this filtration module.Though the technology of this patent can solve the partly problem of incrustation, but still its limitation arranged, because the microorganism mud and the filtration module of biological treatment are in together in the same reaction groove, make and keep higher suspension solids content (microorganism mud height simultaneously, be easy to decomposing pollutant), and the high water flux density of thin-film module becomes awkward.This summary of the invention of announcing No. 593167 Taiwan patent will be merged in this case in the reference mode.
Summary of the invention
Main purpose of the present invention is to provide a kind of and overcomes known film and can not have the higher suspension solids content simultaneously concurrently and keep the new technology of the shortcoming of high water flux density from bio-reactor.
In order to realize the foregoing invention purpose, the present invention proposes to utilize the notion of biological treatment and solid-liquid separation function distinguishing, the biomembrane draining treament system of being finished comprises bacteria bed district (biologicalfiltration bed zone) and divided thin film abscission zone (membrane separation zone).The bacteria bed district utilizes porous carrier (carriers) as Biomedia (media), because of it has the chance that vast surface-area can increase suspended solids in the waste water (SS) interception, and provide space as microorganic adhesion, growth and propagation, therefore can accumulate the biofilm microorganisms of a large amount of and specific group, help to reach the purpose of removing all contaminations.Because the bacteria bed district is a kind of mode of sludge immobilization growth, the SS concentration that goes out flowing water can reach very low degree, significantly alleviate the load of subsequent thin film disengaging zone solid-liquid separation, so, the flux of membrane filtration module (module) and stability obviously increase, and can produce the second best in quality clarifying treatment water.And, effective control to membrane filtration module surface dirt (fouling), reduce film pressure (transmembrane pressure) and energy waste and back flushing frequency, and then effectively prolong membrane filtration module work-ing life, also can shorten the hydraulic detention time (HRT) of treatment trough and reduce the volume in divided thin film abscission zone relatively, help the cost that reduces construction and Operation and Maintenance.
The present invention has following advantage:
Promote treatment trough efficient;
The mud solid-liquid separation is simple;
The functional stabilization height, water quality treatment is good;
Be applicable to low concentration wastewater, can under high hydraulic load, operate;
Reduce and be provided with and running cost.
