TREATMENT METHOD FOR WASTE WATER OF EMULSION TYPE

The treatment of water-soluble oil waste water, such as paraffin wax emulsion, silicon oil emulsion or edible oil emulsion, comprises (A) adjusting the pH of the oily waste water at 4 by adding HCl or NaOH ; (B) adding inorganic polymer compound of formula PHC(Al2(OH)2-Cl6-n)m in the ratio of 1-5% w...

Summary:The treatment of water-soluble oil waste water, such as paraffin wax emulsion, silicon oil emulsion or edible oil emulsion, comprises (A) adjusting the pH of the oily waste water at 4 by adding HCl or NaOH ; (B) adding inorganic polymer compound of formula PHC(Al2(OH)2-Cl6-n)m in the ratio of 1-5% with respect to waste water, where n=1-5 and m<=10 ; (C) adjusting the pH at 7 by adding NaOH ; (D) maintaining the concentration of waste water at 0.05-0.1% ; and (E) adding a polymer compound to produced nuclei to make the big flocs with high density.
