EXPERIMENTAL STUDY ON DISPOSAL WASTE DRILLING LIQUID WITH CATIONIC POLYELECTROLYTE
Li Gang, Zhu Mo, Qian Jialin
The compound flocculant consisted of cationic polyelectrolyte as a flocculant and aluminum sulfate salt as a coagulant can thoroughly break down the colloid system of the waste drilling liquid and make the waste mud solid liquid separated. The surface charge neutralization of suspended particles and the flocculation mode of solid particles in waste drilling liquid caused by cationic polyelectrolyte were studied experimentally.The result showed that cationic polyelectrolyte with a great molecular weight had better flocculability than that with a small molecular weight.Addition of flocculant and coagulant should be proper.
