Further, each filter membrane is respectively connected with pump；Membrane filtration is not natural filtration, it is necessary to which pump provides pressure, increase
Head.
In one embodiment of the present utility model, operation principle of the present utility model：
Continuous and automatic sewage-treatment plant suitable for powder sorbent as shown in Figure 1, by left and right two systems group
Into a set of use, a set of regeneration, can also being as needed adjusted, be used in parallel or in series, two systems include simultaneously
Reaction system, filtration system and control system.Two reaction systems are respectively left reaction system and right reaction system, left reaction system
System includes the first reaction tank 1 and the first filter membrane 10, and right reaction system includes the second reaction tank 12 and the second filter membrane 13；
Left reaction system as shown in Figure 1 includes the first reaction tank 1, pump, agitator 3 and a series of pipelines.First reaction tank 1
For upper opening type, powder adsorbent can be added.Waste water enters in reaction tank from the wastewater inlet pipe 4 of the bottom of the first reaction tank 1,
Fully react, adsorb with the powder adsorbent in pond.Waste water is purified after harmful substance in waste water enters adsorbent, but this
When waste water still mixed with powder adsorbent.After reaction, the mud mixture of waste water and adsorbent is entered by the effect of pump
Enter the first filter membrane 10 being separated by filtration in system, filter membrane is silicon carbide ceramic membrane, and aperture is much smaller than adsorbent particle diameter, can be effective
Filtering；Clear water after the adsorption cleaning of ceramic membrane filter outside waste water outlet pipe 8 by arranging or entering next stage water process list
Member, the concentrated water for being mixed with adsorbent are then back to the first reaction tank 1 and continued and waste water reaction, and adsorbent is dense in the first reaction tank 1
Degree can remain unchanged substantially, so that it is guaranteed that the effect of adsorption treatment；Opened after flux depression to the certain value of filter membrane anti-
System 11 is washed, ceramic membrane is cleaned, by such a mode, the high flux of film can be kept, while maintain the first reaction tank 1
The concentration of interior adsorbent is constant.
When the adsorbent in the first reaction tank 1 is adsorbed close to saturation, the valve of wastewater inlet pipe 4, the first reaction tank 1 are closed
Stop water inlet, open the valve of wastewater inlet pipe 4 of right system, waste water enters the second reaction tank 12, and waste water is carried out by right system
Reason；Remaining waste water goes successively to the first filter membrane 10 by pump in first reaction tank 1, and remaining filter water continues through waste water outlet pipe
8 outflows, continue for some time, are concentrated equivalent to the waste water in the first reaction tank 1.After concentration to a certain extent, open
The valve of desorbed solution water inlet pipe 5 of first reaction tank 1, desorbed solution enter the first reaction tank 1, start the adsorbent progress to left system
Backwash and regeneration, adsorbate enters in desorbed solution during backwash and regeneration, and desorbed solution and powder adsorbent are entered by the first filter membrane 10
Row separation, giving up, analytically liquid outlet pipe 9 flows out backwash liquor, and concentrated water returns to the first reaction tank 1, and powder adsorbent continues solution and is drawn to
Attached dose of regeneration completely；The valve of desorbed solution water inlet pipe 5 is closed when left system regeneration is completed, waste water continues through in the first reaction tank 1
Water pump enters membrane filtration, and analytically liquid delivery port excludes for water outlet, and adsorbent obtains adsorbent in pond with concentrate recirculation to pond
It is stand-by to concentration.Then same operation in turn after adsorbent adsorption saturation in second reaction tank 12.
When absorption or parsing, working long hours for ceramic membrane can all cause membrane flux to reduce, when flux is reduced to certain value
Shi Kaiqi backwashing systems 11, backwash water are that clear water adds compressed air, efficiently get the powder sorbent on membranous wall express developed and return to instead
Ying Chi, filter membrane system can recover function.
When waste water water, which fluctuates, to be increased, left and right two system, parallel processing waste water can be opened simultaneously, water process amount can increase
Double；Increase when fluctuation influent concentration occurs for waste water quality, can be by two when first order reaction is unable to reach standard of drainage requirement
Order reaction pond is connected, and carries out 2 absorption, ensures that effluent quality is up to standard.
Control system after all operational modes of this equipment all program automatically controls, and mainly has 1. left and right system transposition fortune
Row, the 2. normal mode of backwash, the paralleling model of reply burst big yield, 3. series model of reply burst variation water quality etc.,
The work of backwashing system 11 is also to be set automatically according to run time or membrane flux.Control system can select system after a kind of pattern
Whole automatic runnings are convenient, accurate, it is necessary to worker only needs operating in a key during switching working mode.
In summary, it is described be applied to the automatic water softener that powder sorbent persistent loop uses can overcome it is glutinous
Great soil group adsorbent is dfficult to apply to the problem of actual sewage processing engineering so that the extensive use of clay class adsorbent turns into can
Energy；Powdered absorbent may be directly applied to wherein, without shaping, reduce difficulty, process and cost prepared by adsorbent, simultaneously
Reduce the cost of waste water treatment；The continuous processing of waste water can be realized, need not be interrupted in adsorbent adsorption saturation at waste water
Reason goes to carry out the regeneration of adsorbent；Used filter membrane is silicon carbide ceramic membrane, is more suitable for the separation of powder adsorbent and waste water；
Different operational modes automatically controls by the control system of programming, worker may be selected program relief automated system operation, it is necessary to
Also it is operating in a key during change operational mode.
The power for being only preferred embodiment of the present utility model, the utility model can not being limited with this certainly above
Sharp scope, therefore the equivalence changes made according to present utility model application the scope of the claims, still belong to the scope of protection of the utility model.
