Dynamic membrane support body in utilization realization feedwater/sewage disposal of the present invention feeds water/earlier on the supporting network on dynamic membrane support body 505 two sides of realization feedwater/sewage disposal, smear precoating paint before the sewage disposal, as gac etc.To realize that the dynamic membrane support body 505 of feedwater/sewage disposal is placed in the sewage lagoon 501 after having smeared precoating paint, and make the sewage submergence realize the dynamic membrane support body 505 of feedwater/sewage disposal.
Use 507 pairs of upper water-out mouths 107 of realizing the dynamic membrane support body 505 of feedwater/sewage disposal of pump to draw water, because of the supporting network that is coated with precoating paint has adsorption, when making sewage through supporting network, particle wherein is collected on the supporting network, forms Dynamic Membrane.
After the Dynamic Membrane moulding, begin sewage is filtered, make pump 507 extract water purification out from upper water-out mouth 107.And the water outlet of lower outlet 109 flows into another sewage lagoon 503, as the precoating pump around circuit of Dynamic Membrane.
After filtration for some time, when the gap on the Dynamic Membrane face is stopped up by the impurity in the sewage, need carry out demoulding to the dynamic membrane support body 505 of realizing feedwater/sewage disposal.Can make 507 pairs of upper water-out mouths 107 of pump send water, make Dynamic Membrane lose the adherence to bearing surface that is brought by the sewage in the sewage lagoon 501, then Dynamic Membrane just can come off from bearing surface.
Import the sewage in the sewage lagoon 503 in the sewage lagoon 501 this moment, and pump 507 draws water to upper water-out mouth 107 once more, makes and form Dynamic Membrane on the bearing surface once more, and so circulation makes the sewage in the sewage lagoon clean gradually.Upper water-out mouth 107 and lower outlet 109 water outlets simultaneously among this embodiment, increased the circulation that realizes dynamic membrane support body 505 internal water of feedwater/sewage disposal, can reduce the waterpower dead angle of the dynamic membrane support body inside of realizing feedwater/sewage disposal to greatest extent, in servicely also can reduce the precoating time, guarantee the water outlet quality.Upper water-out mouth 107 not only can be used as and draws water, water delivery nozzle, and the precoating pump around circuit that equally also can be used as Dynamic Membrane is used.Lower outlet 109 also not only uses as the precoating pump around circuit of Dynamic Membrane, equally also can draw water and send water.
The present invention proposes a kind ofly to realize feeding water in addition/assembly of sewage disposal, and in order to feedwater or sewage are handled, it comprises dynamic membrane support body, upper water-out pipe and the lower discharging tube of a plurality of realization feedwater/sewage disposals.All realize the assembling that is arranged in parallel of the dynamic membrane support body of feedwater/sewage disposals, can assembly hole be set by the framework both sides and assemble.Wherein, the dynamic membrane support body of the single realization feedwater/sewage disposal in the assembly of this realization feedwater/sewage disposal is identical with the dynamic membrane support body structure of above-mentioned realization feedwater/sewage disposal, no longer repeats to set forth herein.All realize upper water-out pipe of upper water-out interruption-forming of the dynamic membrane support body of feedwater/sewage disposals in the assembly of this realization feedwater/sewage disposal.All realize that the lower outlet of the dynamic membrane support body of feedwater/sewage disposals forms a lower discharging tube in the assembly of this realization feedwater/sewage disposal.
See also Fig. 6, it realizes feeding water/the component application synoptic diagram of sewage disposal for the embodiment of the invention a kind of.
Use 507 pairs of upper water-out pipes 603 of realizing the assembly 601 of feedwater/sewage disposal of pump to draw water, because of the supporting network that is coated with precoating paint has adsorption, when making sewage through supporting network, particle wherein is collected on the supporting network, forms Dynamic Membrane.
After the Dynamic Membrane moulding, begin sewage is filtered, make pump 507 extract water purification out from upper water-out pipe 603.And the water outlet of lower discharging tube 605 flows into another sewage lagoon 503, as the precoating pump around circuit of Dynamic Membrane.
After filtration for some time, when the gap on the Dynamic Membrane face is stopped up by the impurity in the sewage, need carry out demoulding to the dynamic membrane support body 505 of each realization feedwater/sewage disposal in the assembly 601 of realizing feedwater/sewage disposal.Can make 507 pairs of upper water-out pipes 603 of pump send water, make Dynamic Membrane lose the adherence to bearing surface that is brought by the sewage in the sewage lagoon 501, then Dynamic Membrane just can come off from bearing surface.
Import the sewage in the sewage lagoon 503 in the sewage lagoon 501 this moment, and pump 507 draws water to upper water-out pipe 603 once more, makes and form Dynamic Membrane on the bearing surface once more, and so circulation makes the sewage in the sewage lagoon clean gradually.Upper water-out pipe 603 and lower discharging tube 605 water outlets simultaneously among this embodiment, increased the circulation of dynamic membrane support body 505 internal water of each realization feedwater/sewage disposal in the assembly 601 of realizing feedwater/sewage disposal, can reduce the waterpower dead angle of the dynamic membrane support body inside of realizing feedwater/sewage disposal to greatest extent, in servicely also can reduce the precoating time, guarantee the water outlet quality.Upper water-out pipe 603 not only can be used as and draws water, water delivery nozzle, and the precoating pump around circuit that equally also can be used as Dynamic Membrane is used.Lower discharging tube 605 also not only uses as the precoating pump around circuit of Dynamic Membrane, equally also can draw water and send water.Wherein the aligned gaps between the dynamic membrane support body 505 of the realization feedwater/sewage disposal in the assembly 601 of realization feedwater/sewage disposal can adjust according to different demands such as sewage compositions.
The present invention has following some advantage with respect to prior art:
One, owing to adopted the structure of upper and lower water outlet and water distribution passage, can reduce the waterpower dead angle of the dynamic membrane support body inside of realizing feedwater/sewage disposal to greatest extent.In servicely can reduce the precoating time, guarantee the water outlet quality.
Two, flat supporting layer, water distribution passage and supporting network are welded to each other into an integral body, effectively improve supporter intensity, go for malleation feedwater and the negative pressure different operating modes of drawing water, and have the multi-usage characteristics.
Three, realize the dynamic membrane support body one plate structure of feedwater/sewage disposal, make it be easy to the parallel grip assembly that is assembled into of polylith, thereby can handle the feedwater/sewage of different flow.
More than disclosed only be several specific embodiment of the present invention, but the present invention is not limited thereto, any those skilled in the art can think variation, all should drop in protection scope of the present invention.
