| Abstract: | A novel inorganic polymer composite flocculant——PAZSC（poly-aluminum zinc silicate chloride） is synthesized by sodium silicate,aluminum chloride and zinc chloride under normal temperature and pressure.Then the oily waste water is tested.The best flocculation condition is determined that the optimal dosage is 35mL,the most suitable range of pH is 7～8,and the best mole ratio of zinc,aluminum and silicon is 1：1：2.At this time the removal rates of turbidity is 98.9%,the removal rates of chromaticity is 91.3%,and the removal rates of COD is 71.8%.The check experiment of PASC is done,and the results indicate that the properties of PAZSC are superior to that of PASC. |
