Water.
During film filter is in rotating operation pattern, support body 10 and membrane module 12 pass through motor, transmission chain wheel 9,
The drive system of chain and swivel joint 15 composition drives rotation.It is computed, as long as motor rotation speed is more than 4r/min, you can
The water in reactor body 8 is made to be in turbulent state, the current now being formed compare common operation to the scouring force on film silk surface
Mode is higher, can preferably suppress the formation of film silk surface mud cake and the blocking of micropore, the eddy motion form of water body simultaneously
Mud, water mixing can be made more uniform, improve Biochemical Treatment.Because rotating speed is very low, energy consumption of electrical machinery can maintain low-level, instead
Answer the internal aeration of device body 8 can carry out interval limited aeration according to oxygen concentration it is ensured that the living environment of aerobic sludge, reduce and expose
Gas energy consumption.Produce water and can be set as continuously producing aqueous mode, improve system aquifer yield.
During film filter is in interior circulation operational mode, rely on membrane module 12 under swivel joint 14 one end
Position aeration tube 13 carries out continuous variable aeration, produces water and produces aqueous mode using interval, and the time is set as producing water 8 minutes, rests 2 points
Clock.Because film silk internal negative pressure is larger during producing water, aeration rate is according to gas-water ratio 20：1 is set, to prevent from making tolerance product public
Larger particles in sewage are cut into smaller particle by raw intensive bubble, lead to film silk surface micropore depth to block.Stop producing water
Period, aeration rate is according to gas-water ratio 40：1 is set, and washes away attachment by the intensive gas and water mixed flow that big aeration rate produces
Mud in film silk surface.As shown in Fig. 2 membrane module 12 be placed between the first dividing plate 17 and second partition 18, first
Between dividing plate 17 and second partition 18, due to aeration produce rising bubble can drive water body rise, thus formed the gas of rising,
Water mixed flow.Now, the gas and water mixed flow that outside meeting self-assembling formation declines, material is thus formed as shown by the arrows in Figure 2
The flowing trend of gas and water mixed flow, as interior circulation.Interior circulation can accelerate the flow velocity of gas and water mixed flow, and then it is right to strengthen it
The scouring force on film silk surface, suppresses fouling membrane.
Above two operational mode is in actual motion based on rotating operation pattern, when machinery check and repair or other are special
During situation, switch to interior circulation operational mode, to meet the demand of uninterrupted production.
