Greatly, and along with the discharge of large amount of sewage, since water resource is limited, the problem of sewage treatment becomes global primary study.It is existing
Sewage disposal technology be mainly membrane separation technique, be positive infiltration technology and inverse osmosis technology respectively.Wherein forward osmosis membrane point
Utilizing itself osmotic pressure difference from technology is driving force, and spontaneous realization Water transport almost retains many pollutants, is realized
The features such as consuming energy, low, processing water is big, good separating effect, is widely applied to water process, especially in sea water desalination, potable water
Good application prospect is shown in terms of reason and sewage treatment.The core of positive infiltration technology is forward osmosis membrane, existing positive infiltration
Film is formed using organic synthesis material roll paper, by grid between diaphragm and diaphragm, is then carried out glue and is sealed, technique is multiple
It is miscellaneous, furthermore drive the cyclic utilization rate of liquid low in sewage disposal system, therefore it is simple to design a kind of filtration membrane elements preparation process,
The sewage-treatment plant for improving driving liquid cyclic utilization rate is technical problem to be solved.
Summary of the invention
The purpose of the utility model is to overcome defects of the existing technology, provide a kind of filtration membrane elements preparation process letter
It is single, improve the sewage-treatment plant of driving liquid cyclic utilization rate.
Realizing the technical solution of the utility model aim is: a kind of sewage-treatment plant, has sewage water inlet pipe, positive infiltration
Diaphragm, grid, putamina, driving liquid pipe road, sewage enter putamina by sewage water inlet pipe, and forward osmosis membrane piece is tightly attached to grid two
Side, grid is in putamina, and by ultrasonic bonding in grid two sides, the grid upper end is equipped with drives the forward osmosis membrane piece
Hydrodynamic interface, driving liquid interface with driving liquid pipe road connect, the grid lower end be equipped with driving liquid outlet, driving liquid export and
The connection of liquid dilution outlet tube is driven, the import of the driving liquid dilution outlet tube and reverse osmosis unit connects, described
For reverse osmosis unit outside putamina, the reverse osmosis unit is equipped with filtering water outlet, the outlet and drive of the reverse osmosis unit
The connection of hydrodynamic pipeline.The grid is arranged in putamina side by side vertical uniformly.It is solid by membrane component between the grid
Determine item to be secured transverse in putamina.
After adopting the above technical scheme, the utility model have the effect of it is following positive:
(1) the film unit preparation process of the utility model is ultrasonic bonding, and ultrasonic bonding is quickly accurate, and operation is just
Victory, mechanization production do not need to preheat, and quality is reliable and stable, avoid adhesive, can largely reduce artificial, reduction
Production cost, soldering opening is uniform, not damaged and scratch, indeformable, will not as manually having the residual trace of adhesive using adhesive,
Intensity is high, air-tightness is good, water-tight.
(2) the independent driving liquid runner design of the utility model, the driving liquid of realization are recycled practical, substantially reduce sewage
Processing cost.
(3) filter type of the utility model is cross-flow filtration, and sewage will form a kind of shearing when being parallel to film surface flowing
Power takes away the trapped substance being detained on film surface, can avoid pollution object in this way and deposit in filter membrane surface, simplify the cleaning of later period film
Treatment process is generally directly rinsed with clear water.
Detailed description of the invention
In order to make the content of the utility model be easier to be clearly understood, below according to specific embodiment and combine attached
Figure, is described in further detail the utility model, wherein
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the film unit structural schematic diagram of the utility model.
Numbering in the drawing are as follows: 1 is sewage water inlet pipe；2 be driving liquid interface；3 be driving liquid inlet tube；4 be forward osmosis membrane
Piece；5 be membrane component fixed strip；6 be putamina；7 be the outlet of driving liquid；8 be driving liquid dilution outlet tube；9 be filtering water outlet；
10 be reverse osmosis unit；11 be driving liquid pipe road；12 be grid.
Specific embodiment
(embodiment 1)
See that Fig. 1 to Fig. 2, the utility model have a kind of sewage-treatment plant, there is sewage water inlet pipe 1, forward osmosis membrane piece
4, grid 12, putamina 6, driving liquid pipe road 11, sewage enter putamina 6 by sewage water inlet pipe 1, and grid 12 is in putamina 6, lattice
Net 12 is arranged in side by side vertical uniformly in putamina 6, is secured transverse in putamina 6 between grid 12 by membrane component fixed strip 5,
For forward osmosis membrane piece 4 by ultrasonic bonding in 12 two sides of grid, 12 upper end of grid is equipped with driving liquid interface 2, drives liquid interface 2
It is connect with driving liquid pipe road 11,12 lower end of grid is equipped with driving liquid outlet 7, driving liquid outlet 7 and driving liquid dilution outlet tube 8
