Circulation flows between water stream channel 230, to strengthen mass transfer, improves the mass transfer in the ozone fluid bed processing unit 200
Rate makes water outlet more high-quality stable, and reduces cost of sewage disposal.
Specifically, biomembrane combined treatment unit 300 includes：Second shell 310, be arranged in second shell 310 every
The biological respinse space 330 and membrane filtration space 340 that plate 320, partition board 320 limit in second shell 310.Wherein,
Two shells 310 are provided with the second water inlet 30 close to the side in biological respinse space 330, the second water inlet 30 respectively with inlet tank
100 and first water outlet 20 be connected, second shell 310 is provided with the second water outlet at the top of 340 side of membrane filtration space
Mouthfuls 40, bio-carrier 350 is provided in biological respinse space 330, and the bottom in biological respinse space 330 is provided with the second exposure
The bottom of gas port 361, partition board 320 is provided with the first throughbore 321, and membrane module 341 is provided in membrane filtration space 340, and
The bottom in membrane filtration space 340 is provided with membrane filtration aeration opening 362.The not only resistance to punching of biomembrane combined treatment unit 300 as a result,
Load is hit, simple structure is compact, and floor space is small, and sludge bulking rate is low, reduces dirt of the free microorganism to membrane module 341
Dye, and have further the advantage that：On the one hand, membrane module 341 can filter the microorganism to fall off, to keep water outlet more high-quality
Stablize；On the other hand, sewage flows into membrane filtration space 340 from the first throughbore 321 of 320 bottom of partition board, and in membrane filtration
Under the action of the air water lift that the aeration of aeration opening 362 generates, during the water outlet 20 at 310 top of second shell is discharged,
341 surface of membrane module can be cleaned, fouling membrane is further reduced, reduces operating pressure and production cost.
In order to facilitate understanding, first below to that can be realized according to the depth waste water treatment system of the utility model embodiment
The principle of above-mentioned advantageous effect illustrates：
On the one hand, inventor has found, current catalytic ozonation reactor generally existing the catalysis oxidation efficiency is relatively low, at
The problems such as this is higher.Inventor has found that this is mainly by ozone, sewage and catalyst (i.e. gas-liquid-solid three-phase) by further investigation
Contact be not enough caused by.For example, traditional ozone packed bed reactor, the way of contact of ozone, sewage and catalyst
Relatively simple, the general only haptoreaction by way of concurrent or anisotropic flow contacts not between ozone, sewage and catalyst
It is enough abundant, to limit the mass transport process of ozone and dirty Organic substance in water, cause catalysis oxidation efficiency integrally relatively low, it is difficult into
One step reduces the COD value of sewage, and causes ozone utilization rate low, the higher problem of cost of sewage disposal.It is new according to this practicality
The ozone fluid bed processing unit 200 of type embodiment, ceramic film component 220 is arranged at the center of first shell 210, that is, is being made pottery
Between porcelain membrane module 220 and the side wall of first shell 210, top surface and bottom surface, the water stream channel by interconnecting is reserved
230, sewage can be from the bottom of ceramic film component 220, in the effect for the air water lift that the first aeration opening 240 aeration generates as a result,
Under, the top of ceramic film component 220 is risen to, and pass through the water between ceramic film component 220 and the top surface of first shell 210
The downward circulation of circulation road 230B, by between ceramic film component 220 and the side wall of first shell 210 water stream channel 230A and
Water stream channel 230C between ceramic film component 220 and the bottom surface of first shell 210, is back to ceramic film component from bottom again
In 220.Sewage circulation between ceramic film component 220 and water stream channel 230 flows as a result, and sewage can be to ceramic membrane
The all directions of 220 surrounding of component carry out circulation flowing, to greatly strengthen mass transfer, improve ozone fluidized bed processing list
Mass transfer rate in member 200, makes water outlet more high-quality stable, and reduce cost of sewage disposal.
On the other hand, inventor has found, currently with the method for microorganism treating sewage, there are some defects.For example,
Although biofilm has the advantages that anti impulsion load, floor space are small, sludge bulking rate is low, free microorganism in reactor
It is less, however in actual operation, micropopulation is easy to fall off from bio-carrier surface so that and water outlet clarity reduces,
Effluent quality is unstable.On the other hand, membrane bioreactor (MBR) is used as one kind by film separation unit and biological processing unit phase
In conjunction with novel water technology, have many advantages, such as to be discharged that high-quality stable, surplus sludge volume is few, floor space is small, however it is traditional
MBR in sludge concentration it is higher, the presence of free microorganism is easy to form fouling membrane, leads to the increasing of discharge pressure and operating cost
Add.And according to the biomembrane combined treatment unit 300 of the utility model embodiment, with reference to figure 1, pass through technological transformation, on the one hand,
On the basis of traditional biological embrane method, the side setting membrane filtration space 340 in biological respinse space 330, and membrane filtration is empty
Between be provided with membrane module 341 in 340, membrane module 341 can effectively filter the micro- life to fall off from 350 surface of bio-carrier
Object group, to keep water outlet more high-quality and stablize, the shortcomings that improving traditional biological embrane method reactor；It on the other hand, will be traditional
MBR in biological processing unit replace with the biological respinse space 330 with bio-carrier 350, reduce traditional MBR
Pollution of the middle free microorganism to MBR membrane modules, the shortcomings that improving traditional MBR.Also, according to the utility model embodiment
Biomembrane combined treatment unit 300 passes through the flow path of ingehious design sewage, i.e. first water of the sewage from 320 bottom of partition board
Recirculation hole 321 flows into membrane filtration space 340, is aerated by membrane filtration aeration opening 362 under the action of generating air water lift, sewage can
With the surface of flush clean membrane module 341, fouling membrane is reduced, is reduced to operating pressure and cost.
Another aspect, inventor have found that there are some to lack for the depth waste water treatment system comprising multiple processing units at present
It falls into.Current depth waste water treatment system generally can be by multiple sewage treatment units for the organic matter in fully degraded sewage
