Mixing chamber 240 is located at the top of filtrate chamber 230, that is, the top of some membrane tubes 220, and inlet 211 and air inlet 212 are with mixing
Close chamber 240 to connect, the waste water that is entered by inlet 211 and by progress in the gas collection that air inlet 212 enters to mixing chamber 240
Mixing, water distribution gas pipe 200 by after the gas in mixing chamber 240 and waste water by a certain percentage uniform mixed allocation, gas and
Waste water is filtered into some membrane tubes 220.Thus, the good mixing effect of waste water and gas, beneficial to water distribution gas pipe 200 to gas
Body and waste water carry out rationed.
Further, as shown in Figure 1, mixing chamber 240 is divided into mixing section 241 and lower mixing section 242 along the vertical direction, into
Liquid mouth 211 and air inlet 212 are connected with upper mixing section 241, and lower mixing section 242 is connected with some membrane tubes 220, upper mixing section 241
Cross-sectional area it is constant from top to bottom, the cross-sectional area of lower mixing section 242 from top to bottom gradually increases.Waste water and gas are upper mixed
Section 241 is closed after fully mixed, into lower mixing section 242, since the cross-sectional area of lower mixing section 242 from top to bottom gradually increases
Greatly, waste water and gas can be with uniform divided flows to each membrane tube, thus, the good mixing effect of waste water and gas, and can carry
The filter efficiency of high membrane tube.
One embodiment according to the present utility model, have in housing 210 positioned at the lower section of filtrate chamber 230 and with some membrane tubes
The reflux collecting chamber 250 of 220 connections, reflux collecting chamber 250 are connected by return duct 500 with bioreactor 100, return duct
Delivery pipe 510 is connected with 500.For example, in the embodiment shown in fig. 1, reflux collecting chamber 250 is located at the lower section of filtrate chamber 230,

Sludge in waste water is retained by some membrane tubes 220, is precipitated in reflux collecting chamber 250, the sludge mixing in the collecting chamber 250 that flows back
Liquid is partly refluxed to bioreactor 100 by return duct 500, and another part passes through the delivery pipe 510 that is connected on return duct 500
Discharge.Thus, sludge remaining in some membrane tubes 220 can be discharged, avoids some membrane tubes 220 of sludge blockage so as to influence membrane tube
Filter effect, meanwhile, the sludge part in waste water is back in bioreactor 100, it is ensured that in bioreactor 100
The enough demand of sludge.
Alternatively, reflux collecting chamber 250 is divided into reflux collection section 251 and lower reflux collection section 252 along the vertical direction, on
Reflux collection section 251 is connected with some membrane tubes 220, and lower reflux collection section 252 is connected by return duct 500 and bioreactor 100
Logical, the cross-sectional area of upper reflux collection section 251 is from top to bottom gradually reduced, the cross-sectional area of lower reflux collection section 252 by up to
Under it is constant.Thus, beneficial to mud mixture by upper reflux collection section 251 and lower reflux collection section 252 discharge reflux collecting chamber
250, remaining sludge is less and to discharge effect good.
One embodiment according to the present utility model, as shown in Figure 1, the axial direction of inlet 211 is vertically extending, into
The axial direction of gas port 212 is horizontally extending.Gas enters mixing chamber 240 by air inlet 212 in the horizontal direction, and waste water is along vertically
Direction enters mixing chamber 240 by inlet 211, after gas is mixed with waste water, due to the direction that gas is blown into and waste water flowing
Direction is vertical, and waste water forms rotating vortex, it is possible thereby to increase flow velocity of the waste water when passing through membrane tube, so as to improve membrane tube
Filter effect, after gas enters membrane tube with the direction of water flow rotary, the friction paths of gas and film surface are longer, can improve gas
The effect that body cleans film surface.Thus, it is possible to improve the filter effect of membrane tube, while reduce fouling membrane.
