1. , a kind of polyaluminium chloride e-poly-dimethyl-diallyl-ammonium chloride compound coagulant is characterized in that being prepared from by following steps, and promptly (1) places polymerize aluminum chloride PAC dry powder or solution in the mixing kettle, adds the water allotment and obtains aluminium salt PAC content with Al 2O 3Count its massfraction and be 10.5%~

  • 20.5% PAC solution;

    (2) stir this PAC solution at normal temperatures, add solid content and count 40%~

    75% and have the Poly Dimethyl Diallyl Ammonium Chloride PDMDAAC colloid that the feature k value is 0.5~

    4.7dL/g with massfraction, the content that makes PAC in the mixing solutions is with Al 2O 3Meter is 20.0;

    1~

    2.0;

    1 with the mass ratio of PDMDAAC;

    (3) mix solution at normal temperatures and dissolve fully, obtain stable polyaluminium chloride e-poly-dimethyl-diallyl-ammonium chloride compound coagulant up to the PDMDAAC colloid.
