Embodiment
For making your auditor can further understand structure of the present utility model, feature and other purposes, now be described in detail as follows with accompanying drawing in conjunction with appended preferred embodiment is attached, the illustrated embodiment of this accompanying drawing only is used for explanation the technical solution of the utility model and non-limiting the utility model.
The utility model uses the water purification medicament to catch pollutants in waste water, and pollutent is transformed the water-fast throw out of formation, and utilize one or more snippets membrane filter unit, and carry out the membrane filtration of multistage, the middle quality that makes it to produce meets the water inlet requirement of reverse osmosis.The high density flocs unit that final treatment trough is discharged, that is so-called waste liquid or mud can directly enter sludge dewatering treatment, need not to arrange sludge thickener.
During membrane filtration, be accumulated in the lip-deep glue plumage of ultra-filtration membrane (Ultra Filtration Membrane) and can densification become to have the mud cake that increases the filter pressure impedance, the upward water flow that the aeration that produces by the gas blower at the bottom of the treatment trough causes can suppress formed hmc on the ultra-filtration membrane surface.Be provided with variable valve between gas blower and each treatment trough, can adjust or strengthen aeration intensity, remove the too much mud cake of accumulation on the face to wash away.
Wherein, owing to use a plurality for the treatment of troughs to filter, the flco substrate concentration improves by groove in the groove.Ultra-filtration membrane in the treatment trough of most end, because bear the throw out concentration of maximum concentration, it is the fastest that face is piled up the speed of mud cake, therefore needs the special aeration of strengthening to scrub face, and reduce the membrane filtration flux.
Hereinafter with reference to correlative type, the wastewater treatment equipment according to the utility model preferred embodiment is described, in order to make it easy to understand, the same components among the following embodiment illustrates with identical symbology.
See also Fig. 1, wastewater treatment equipment of the present utility model comprises a feeder 1 and a treatment trough 2, and this feeder 1 interconnects with this treatment trough 2, and can make wastewater feed to this treatment trough 2.
This feeder 1 comprises an opening for feed 101, a dosing opening for feed 102 and a line mixer 103.
This opening for feed 101 enters in the treatment trough 2 of this wastewater treatment equipment for waste water, and the waste water of indication means usually at chemical grinding and adds man-hour (Chemical Mechanical Polishing, the waste water that CMP) produces in the utility model.
This dosing opening for feed 102 is to enter in the treatment trough 2 of this wastewater treatment equipment for aforementioned water purification medicament, purifies medicament and is selected from aluminium salt such as Tai-Ace S 150 (aluminum sulfate), polymerize aluminum chloride (PAC), sodium aluminate; Molysite such as iron(ic) chloride, ferrous sulfate, bodied ferric sulfate and can use throw out (glue plumage) in water separately.
This line mixer (Static mixer) 103 interconnects with this opening for feed 101 and this dosing opening for feed 102, can will carry out online fast mixing by the waste water of aforementioned opening for feed 101 chargings and by the water purification medicament of aforementioned dosing opening for feed 102 chargings, produce water-fast throw out, and this throw out is fed in the treatment trough 2.
This treatment trough 2 comprises one first groove 21, one second groove 22, a three-flute 23, a gas blower 3 and a water outlet 4, and wherein the throw out that produces of the line mixer 103 of this feeder 1 is in first groove 21 of this treatment trough 2 of charging.
This first groove 21, second groove 22 and three-flute 23 are respectively arranged with film filter 211,221,231, and first groove 21 and second groove 22 are interconnected and second groove 22 and three-flute 23 are interconnected, and this first groove 21, second groove 22 and three-flute 23 are to be interconnected with the series connection form.Film filter 211,221, the 231st, the tabular film of negative pressure leaching or tubular fibre cortina.Membrane pore size is 0.01 to 10 micron, is preferably 0.03 to 0.1 micron.Membrane material can be polyvinyl chloride (PVC), polyacrylonitrile (PAN), polypropylene (PP), polysulfones (PS), polyethersulfone (PES) or polyvinylidene difluoride (PVDF) (PVDF).The bottom land of this first groove 21, second groove 22 and three-flute 23 leads to mutually with this gas blower 3 respectively, and be provided with variable valve 31,32,33, therefore can be with air aeration bottom the diaphragm of each groove, make and produce bubble and the current that upwards flow between the diaphragm, wash away the film surface, suppress face and produce the accumulation of glue plumage.Film filter 211,221,231 leaches the water of purification via negative pressure-pumping.The top of this first groove 21, second groove 22 and three-flute 23 links mutually with this water outlet 4 respectively, and is provided with product water ga(u) ge 41,42,43, and the film of each treatment trough produces water flux and is about 10 to 100L/m
2/ hr is preferably 20 to 50L/m
2/ hr.
In addition, this first groove 21 is provided with acid solution/alkali lye opening for feed 24 and pH-value is measured meter 25, its purpose is the dose that adds by control acid solution/alkali lye, and the pH value of regulating and control in first groove 21 is best scope of carrying out chemical coagulation process, has reached the filter quality of the best.Best pH scope will be according to the characteristic of handled waste water, and it needs to decide via test of many times.Adjust the acid solution of pH value and can use sulfuric acid or hydrochloric acid etc., alkali lye can be selected sodium hydroxide for use.
Moreover three-flute 23 is provided with waste outlet 26, behind the wastewater feed, in first groove 21, disturbs the mixed and glue plumage slaking of slow motion by the current that aeration produces, and is then gone out clean water by film filter 211 suction filtrations of first groove 21, and the glue plumage in first groove 21 is concentrated.The film filter 221 that glue plumage mixed solution in first groove 21 flows into second groove, 22, the second grooves 22 also suction filtration goes out clean water, and the glue plumage in second groove 22 is concentrated again.Second groove 22 flows into the glue plumage mixed solution of three-flute 23 via film filter 231 suction filtrations of three-flute 23, after glue plumage concentration is concentrated again, with glue plumage concentration about 10,000 to 25,000mg/L, directly extracted out with the mud water pump by waste outlet 26, enter sludge dewatering equipment and handle, need not to arrange in addition sludge thickener.
Mandatory declaration be that glue plumage concentration is controlled by the water rate of recovery, the wastewater flow rate of the water yield/charging that the water rate of recovery=membrane filtration produces.Little when the pollution of the waste water of charging, the water purification additive amount of medicament just tails off, and initial glue plumage concentration is few, and therefore, the water rate of recovery can raise.Otherwise, the pollution height of influent stream water, it is big that the water purification additive amount of medicament just becomes, and initial glue plumage concentration height just must reduce the water rate of recovery, makes the glue plumage concentration of three-flute 23 can be too not high, causes the operational difficulty of film filter.
