The result showed that when the ratio of starch, DMC and AM was 2:1:3, the weight of initiator (po-tassium persulfate) was 0.2% of the AM, reaction temperature was 65℃ and reaction time was 5h, the performance of product was the best. The water content in filter cake was 27.6% after the waste drilling mud disposed by the optimization flocculant. The flocculent effect of optimization flocculant was superior to that of other flocculant in market.展开更多
