| Abstract: | The paper introduces the techniques of preparing one new type of flocculant-polyaluminium calcium chloride with the materials of Al2O3 and CaCO3, The results show that it is helpful for the reaction that the baking temperature rises, the proportion of Al2O3 is 70%, the quantity of acide is 70ml and the solubilizatin time is 3 hours .The efficacy of the new flocculant is researched by using the BenXi steelworks gas washing water, it is superior to the traditional polyaluminium. |
