Abstract
The utility model provides a reduce sequencing batch membrane bioreactor membrane pollution device, including reactor, agitating unit, membrane module and vacuum meter, have "concave" shape turning arm in the puddler lower part, pendulum rod one end is cup jointed on the puddler turning arm through the gyration ring, and the pendulum rod other end articulates in membrane module lateral wall lower part, and the higher authority of membrane module is fixed with the ring, and the ring cover is on the fixed axle, and fixed axle both ends overlap joint is followed on the reactor. When the stirring device works, the stirring rod and the lower crank arm rotate around the axis of the stirring rod and drive the rotary ring to perform planar circular motion, so that the oscillating rod does reciprocating motion back and forth while rotating circumferentially, and the oscillating rod drives the membrane component to vibrate while oscillating back and forth. The utility model discloses need not to provide extra power, easy operation can effectively slow down the pollution of batch membrane bioreactor membrane, reduces the membrane and washs the number of times, prolongs the life of membrane module, saves investment and running cost.
Description
Technical field
The utility model belongs to water treatment facilities field, is specifically related to a kind of device that sequencing batch membrane bioreactor film pollutes that reduces.
Background technology
Membrane bioreactor is at home and abroad paid close attention to widely as the new and effective dirty water living creature processing technique of one, and along with the development maturation of membrane technology, in Practical Project, is used widely.And sequencing batch membrane bioreactor can be realized in single-reactor inside nitrification and denitrification, more become the focus of research.
In the operating process of all membrane bioreactors, the permeation flux of film all can reduce gradually, and its main cause is exactly the pollution of film, and therefore to pollute be to affect one of principal element that membrane bioreactor applies to film.The mechanism that causes film to pollute roughly has following: form cake layer, formation precipitation, formation gel layer, adsorption fouling and obstruction and pollute.The film of broad sense pollutes and not only comprises the pollution (irreversible membrane fouling) causing due to irreversible absorption, obstruction, and comprising the formation (reversible membrane fouling) that causes gel layer due to reversible concentration polarization, the two causes the decay of membrane flux in running jointly.
Sequencing batch membrane bioreactor, in the time of work, is divided into aerobic period and anoxic period.Existence in the aerobic period due to aeration, bubble can produce shear action to film surface, can reduce the pollution of film; But while work in the anoxic period, membrane module is almost in actionless state, now the most easily produce microorganism to the adhering to of film surface, pollute and produce film.How reducing film and pollute, extend the operational use time of film, reduce wash number, improve production capacity and efficiency, is the emphasis direction of research.
Summary of the invention
The utility model aims to provide and a kind ofly can effectively slow down the film that sequencing batch membrane bioreactor produces in the anoxic period and pollute, and reduces film wash number, the minimizing sequencing batch membrane bioreactor film polluting device in membrane component and prolong service life.
For this reason, the technical solution that the utility model is taked is:
A kind of sequencing batch membrane bioreactor film polluting device that reduces, comprise reactor, agitating device, membrane module, vacuum meter and drinking-water pipe, it is characterized in that, in the puddler bottom of agitating device with horizontal " recessed " shape connecting lever, fork one end is provided with pivoted loop, pivoted loop is actively socketed on puddler " recessed " shape connecting lever, the fork other end is hinged on the lower sidewall of membrane module, the upper surface of membrane module is fixed with annulus, annulus is enclosed within on fixed axis, and fixed axis two ends are overlapped on the upper along upper of reactor antetheca and rear wall.
Using method of the present utility model and beneficial effect are
In the time that agitating device is worked, puddler rotates around puddler self axis together with bottom " recessed " shape connecting lever, drive the fork pivoted loop being enclosed within on " recessed " shape connecting lever to carry out planar circumferential motion simultaneously, make fork at the circumgyration front-rear reciprocation movement that does simultaneously, and drive membrane module under the effect of fixed axis, in swing, to produce vibration by fork, Oscillation Amplitude is 0.2-1.5cm, its vibration frequency is identical with the rotational frequency of puddler, puddler revolution is 30-180r/min, thereby slows down the pollution of reactor film.In the time that the reading of vacuum meter 8 reaches 20kPa, need to clean membrane module 7.
The utility model does not need the power and the corollary system that provide extra, makes full use of the energy in original system, simple to operate, can effectively slow down the pollution of sequencing batch membrane bioreactor film, reduce film wash number, in the service life of membrane component and prolong, reduce investment outlay and operating cost.
