Embodiment
The utility model is further described below in conjunction with accompanying drawing:
As shown in Figure 1, it includes a plurality of membrane bioreactor modules 4,5,6,7 the utility model, the membrane bioreactor module is provided with water inlet pipe and rising pipe, water inlet pipe on the membrane bioreactor module connects high-order back flushing water tank 20, the rising pipe of membrane bioreactor module is connected to the water inlet interface that sequence of control device 1 is filtered in the gap, and the water outlet interface that sequence of control device 1 is filtered in the gap is connected to system's product water tank 13.The pipeline of membrane bioreactor module water inlet pipe and high-order back flushing water tank 13 is provided with automatic backwash control valve 21,22.The pipeline that the water outlet interface of gap filtration sequence of control device is connected to system's product water tank 13 is provided with suction pump 2,3 and under meter 19.
Open system the utility model intermittent filtration sequence controller 1, open suction pump 2,3 simultaneously, system filtration brings into operation, sewage is entering water outlet header 8,9,10,11,12 respectively behind each membrane filtration in membrane bioreactor module 4,5,6,7 under the suction function of suction pump 2,3, in intermittent filtration sequence of control device 1, behind 1-1,1-2 and the 1-3, send into system by suction pump 2,3 respectively and produce water tank 13 respectively again.
The assembly serial connection that has 3 (also several can be arranged) can carry out intermittent filtration control respectively in the utility model intermittent filtration sequence controller 1 forms, intermittent filtration controller assemblies such as Fig. 2, shown in 3, by the water inlet dish 14 that offers several prosopyles, offer the water tray 16 of a posticum and offer arc flow channels rolling disc 15 compositions stifled that equate with prosopyle quantity with time-out, rolling disc 15 and water inlet dish 14,16 of water trays are by sealing-ring 17 sealings, and each the water inlet interface in the water inlet dish 14 is connected with a water outlet header of membrane bioreactor module.During running, drive the slow uniform rotation of rolling disc by motor reducing transmission device, because of its constitutional features, when prosopyle and rolling disc arc flow channels are met, water outlet is unimpeded, when prosopyle and rolling disc suspended stifled meeting, water outlet suspended, and reached the purpose of control iMBR module intermittent filtration operation thereby so move in circles; The ratio of its flooding time and time out can and be suspended stifled arc length ratio and decide by the arc flow channels, for example, arc flow channels arc length is 8:2 with suspending stifled arc length ratio, when rolling disc rotated a week in per 10 minutes, then filtered water outlet in 8 minutes, the water outlet of 2 minutes time-outs.When progressing into the time-out water outlet, water flow obviously reduces until stopping water outlet fully in the short period of time.
