Abstract
The invention aims to disclose a method for removing copper ions from circuit board waste water. The method comprises the following steps: allowing circuit board sewage to enter a reactive tank through a mixed reactor; adding magnetic seeds, polyaluminium chloride and polyacrylamide into the reactive tank and stirring uniformly, so that the copper ions in the waste water generate floc under the flocculation action of the magnetic seeds, the polyaluminium chloride and the polyacrylamide; purifying the floc by using magnetic separation equipment and allowing the treated water to enter a clean water pool; conveying the floc mixture discharged by the magnetic separation equipment to a separating machine by using a sludge pump and separating the floc mixture into heavy liquid and light liquid; conveying the light liquid into the reactive tank, conveying the heavy liquid into a magnetic separator, allowing the floc mixture to enter the bottom of a box in a loose state under the action of a spray pipe, and separating magnetic powder from the floc under the action of a magnetic field; and conveying the magnetic powder to the reactive tank and discharging the sludge into a sludge pipe for recycling. The method has the advantages of high integrated degree, good treatment effect, small occupied area and simplicity in construction.

Step 1) wiring board sewage gets into reactive tank through mixing reactor;
Step 2) in reactive tank, adds magnetic kind, poly aluminium chloride, SEPIGEL 305 and stir, make that cupric ion produces floc sedimentation in the waste water under the throwing out of magnetic kind, poly aluminium chloride, SEPIGEL 305;
Step 3) purifies floc sedimentation through magnetic separating apparatus, and the water after the processing gets into clean water basin;
The flco mixture that the step 4) magnetic separating apparatus is discharged to separating machine, is divided into heavy-fluid and light liquid with the flco mixture by sludge pumping;
The step 5) light liquid is delivered to reactive tank, and heavy-fluid is delivered to magnetic separator (6), and under the effect of water jet standpipe, the flco mixture is loose condition (of surface) and gets at the bottom of the case, and under the effect in magnetic field, magnetic separates with flco;
Step 6) is delivered to reactive tank with magnetic, and mud enters in the sludge pipe and reclaims.
Further; The centre of said reactive tank is provided with dividing plate, and said dividing plate becomes 45 ° of angles with water (flow) direction, and said reactive tank is arranged to left and right two reactive tanks; In two reactive tanks whisking appliance is set all about said; Opening is offered in the upper end of dividing plate, in two grooves, adds magnetic kind, poly aluminium chloride, SEPIGEL 305 respectively, and whisking appliance fully stirs the mixed solution in two grooves.
That further, said magnetic adopts is Fe
3O
4Fine powder, said Fe
3O
4Fine powder is the ferromagnetism magnetic, the objectionable impurities in can planar water, and it also has the effect of coagulation simultaneously, through said magnetic separating apparatus they is held the back then and removes.
Further; What coagulate that agent adopts is poly aluminium chloride, said poly aluminium chloride is a kind of poly-hydroxy, has the cationic inorganic polymer flocculant of multinuclear complexing body; And it is soluble in water; In the hydrolysate after the said poly aluminium chloride dissolving, what mainly play throwing out is multinuclear poly-hydroxy yang collaterals ion, and this positively charged ion has electrical neutralization absorption bridging effect.
Further, what coagulant aids adopted is SEPIGEL 305, said SEPIGEL 305 high molecular weight water soluble polymer; Be insoluble to most of organic solvents, have good flocculence, can reduce the friction resistance between the liquid; Can make suspended matter through charge neutrality, the bridge formation adsorption.
The invention has the beneficial effects as follows:
Technology of the present invention is removed process for copper relatively with tradition, and it can be optimized and reduce former dosage and reach 50%, and filtration velocity is equivalent to 100 times of settling tank, and integrated level is high, has good treatment effect, and clearance is more than 90%, and floor space is little, the construction simple.
