Detailed description of the invention
Below in conjunction with the accompanying drawings and the technical solution of the utility model is described in further detail by embodiment.
A kind of device for improving MBR film group device antifouling property as shown in Figure 1, mainly includes casing 1, rotary-tray 2, central shaft 3, aeration plate 4 and timing rotation and apparatus for controlling of lifting 5；Wherein:
Film group device to be cleaned is installed in casing 1, and casing 1 is mounted and fixed on the rotary-tray 2 of lower section；
Fixed sequence is criticized aeration plate 4 and is placed in the lower section of rotary-tray 2, is used for exposing scouring air-flow.
Aeration plate 4 is fixed in one end of central shaft 3, and sequentially passes through rotary-tray 2 and casing 1, casing 1, rotary-tray 2 and aeration plate 4 is relatively fixed；Casing 1 can rotate around central shaft 3 or move up and down along central shaft 3, and rotation and apparatus for controlling of lifting 5 are installed on the other end of central shaft 3, controls for above-mentioned rotation, up and down motion quantify (such as rotary speed angle, upstream time distance etc.).
It practice, be owing to rotary-tray 2 can carry out the rotation of certain angle with the central shaft 3 of the geometric center that is positioned at rotary-tray 2 for fixing center of rotation, thus drive the rotation of casing 1, in like manner, it is achieved casing 1 up or descending.
Whole system divides mobile layer and fixed layer on gravity direction from top to bottom；Wherein:
Mobile layer mainly includes casing 1 and the rotary-tray 2 being provided with film group device；
Fixed layer mainly includes central shaft 3 and fixed aeration plate 4；
Preferred as one, the projection of shape of aeration plate 4 is identical with casing 1 with size, can be all rectangle or circle；Aeration plate 4 can use continuous uniform aeration can also use intermittent pulse aeration；Wherein: in the case of intermittent pulse aeration, its aeration period is 2～15s；I.e. gas accumulates 2～15s (preferably about 5s) in aeration plate 4, then instantaneous relase, and intensity than under the conditions of uniform aeration big 2～15 times the most immediately, on the premise of aeration total amount is constant, it is possible to achieve higher instantaneous aeration intensity.
On the one hand, film group device and casing 1 thereof are with rotary-tray 2 around main shaft 3 synchronous rotary clockwise or counter-clockwise, and its swing circle is 12～40s (preferably 20s, under this rotating speed, the state-maintenance to the removal polluted and equipment is best)；On the other hand, film group device and casing 1 Yanzhong mandrel 3 thereof move up and down, its upstream time is 3～12s (preferably 5s), and Top Runby is not more than 10cm, and swing circle, upstroke and time thereof are realized by timing rotation and the apparatus for controlling of lifting 5 being located on central shaft；Action of gravity is then relied on to realize time descending；The up and down motion of film group device and casing 1 thereof mainly cooperates with intermittent pulse aeration, during when low aeration or without aeration, it is in propradation, can be in Convection states with the mixed liquor in casing 1, the pollutants convection diffusion inside and outside casing 1, when aeration is in high impulse state, casing 1 falls, becoming strong convection current with the air-flow row risen, the scouring to film surface is more efficient, the most more conducively pollutant diffusion.By the continuous circulation of above-mentioned state, during film group device purifies water, improve its antifouling property.
