+Processing reuse in heavy metal.
In the prior art, the heavy metal wastewater thereby waste residue amount after treatment that various industries are different is big, complicated component, recycle difficulty, one-time investment and running expense, energy consumption height and technical process complexity thoroughly do not solve always as yet, cause its subject range to be restricted, and can not apply widely.For overcoming these defectives, heavy metal containing wastewater treatment reuse method and device have been carried out development in depth.
The purpose of this invention is to provide and a kind ofly can make the different heavy metal wastewater thereby of various industries discharged wastewater met the national standard or return production line and use after treatment, waste residue is all recycled, one-time investment, running expense and energy consumption low and simple heavy metal containing wastewater treatment reuse method of technical process and device.
The object of the present invention is achieved like this:
Its method is according to heavy metal and objectionable impurities contained in the various industry waste water, the corresponding medicine that purifies of allotment in purifying medicinal cupping, respectively entering mixing effect the sparger simultaneously from branch road separately through the waste water of waste pipe with through the purification medicine of loading valve, and several apertures in sparger spray into purification tank and purify reaction, in in another sparger and its aperture spray into clarifying tank and drip the slit from screen, carrying out again and flocculation reaction with flocculation agent, finish solid-liquid separation for the first time, its solids precipitation thing is built up the bottom in clarifying tank, and waste liquid is pumped in the device by infusion pump and handles.Also used a kind of heavy metal containing wastewater treatment reclamation set, when its working order, the feed liquor valve is opened, residual cake valve cuts out, waste liquid enters between centrifuging engine housing and the centrifugal cyclone plate through fluid inlet, through action of centrifugal force, make waste liquid produce centrifugal cyclone, and make the small-particle in the liquid become macrobead because of colliding mutually, be deposited on the bottom of centrifugal filter again because of the effect of gravity, make waste liquid carry out the solid-liquid separation second time, suspension small-particle remaining in the waste liquid is separated by force by micron order cellular plastic chimney filter, and clear liquid is from the water outlet qualified discharge or return the production line use.When filtering effect decline, close infusion pump and feed liquor valve, open residual cake valve, recoil from water outlet injection clear water or air, till slag has been arranged, and with the solids precipitation thing in its waste residue and the clarifying tank complete reclaim as metallurgical, industrial chemicals or collect transform the back and return production line and use.Disconnect recoil clear water or air then, close residual cake valve, open the feed liquor valve, start infusion pump 8, repeat above-mentioned working process.
Its device is centrifugal filter, it by a side be provided with feed liquor valve, fluid inlet, the upper and lower end top is respectively equipped with water outlet, slag-drip opening, residual cake valve, centre are provided with by the right cylinder of chimney filter grid distributor fixed micron order cellular plastic chimney filter and centrifugal cyclone dividing plate and constitute.
Fig. 1 is a schema of the present invention.
Fig. 2 is the structure enlarged view of centrifugal filter 11 among Fig. 1.
Fig. 3 is the vertical view of Fig. 2.
In the accompanying drawings, 1-purifies medicinal cupping, 2-waste pipe, 3,3 '-sparger, 4-purification tank, 5-screen, among the 6-and flocculation agent, 7-clarifying tank, 8-infusion pump, the 9-fluid inlet, 10-water outlet, 11-centrifugal filter, the 12-slag-drip opening, 13-chimney filter grid distributor, 14-micron order cellular plastic chimney filter, 15-centrifugal cyclone dividing plate, 16-centrifuging engine housing, 17-pre-treatment purification tank.
Embodiments of the invention.
Referring to accompanying drawing, at first the different choice according to last table heavy metal purifies medicine accordingly, opens loading valve K again
1, allow purify medicine through loading valve K
1Heavy metal and objectionable impurities waste water flow into simultaneously in the sparger 3 through waste pipe 2 and purify reaction after the mixing effect in purification tank 4, clarifying tank 7 with in and flocculation agent (mixture of the oxyhydroxide of sodium, calcium and its esters and alum or polymerize aluminum chloride) carry out in and flocculation reaction, the pH value that makes waste water is between 6～9, simultaneously flocculation agent makes suspended particle condense because of static and chemical action, small-particle become the macrobead throw out and be accumulated to the bottom of clarifying tank 7, carry out the solid-liquid separation first time.Open feed liquor valve K
2 Start infusion pump 8 waste liquid is carried out the solid-liquid separation second time through fluid inlet 9 pumps into itself and centrifugal cyclone plate 15 along the tangential direction of centrifuging engine housing 16 between, little suspended particles remaining in the waste liquid are separated by force by micron order cellular plastic chimney filter 14, and clear liquid is from water outlet 10 qualified discharges or return the production line use.When filtering effect decline, close infusion pump 8 and feed liquor valve K
2, open residual cake valve K
3, clear water or air from water outlet 10 injections 0.2～0.3MPa recoiled 2～3 minutes, and 2～3 times repeatedly, till waste residue had been arranged, waste residue and solids precipitation thing can be all as metallurgical, and industrial chemicals or collection transform back time production line and use.And then disconnect recoil clear water or air, close residual cake valve K
3, open feed liquor valve K
2, start infusion pump 8, repeat above-mentioned working process.If the heavy metal-containing waste water that piece surface brings then adds one pre-treatment and staticizes groove 17 as pre-treatment cleaning section (it purifies medicine and adopts interval type to change) before the part rinsing, repeat above-mentioned technical process again and can carry out the heavy metal containing wastewater treatment reuse.
The present invention compares the good effect that produces with prior art:
1, the discharged wastewater met the national standard after processing or be back to production line, the purifying rate height.
2, waste residue and solids precipitation thing all reclaim to be used as and are back to production after metallurgy, industrial chemicals or collection transform.
3, wide accommodation, it is to electroplating, metallurgy, chemical industry, petrochemical industry, process hides, printing and dyeing, papermaking, hospital disinfection sewage, truck washing, oily waste water, diet, the sewage such as life all can be administered effectively.
4, one-time investment, running expense and energy consumption are low.
5, technical process is simple.
