摘　　要：以某矿井高浊度、含少量油的矿井水为研究对象,分别选用“聚合氯化铝(PAC)+聚丙烯酰胺(PAM)”、阳离子改性淀粉、阴离子型聚丙烯酰胺(CPAM)和木质素等4种水处理剂进行混凝实验。结果表明,在水质相同、搅拌速度为80 r·min^(-1)、搅拌时间为5 min、絮凝剂用量为20 mg·L^(-1)、静置时间为5 min的条件下,阳离子改性淀粉的投加量少,反应时间快,所形成的絮体较密实,混凝效果最好,对油也有很好的吸附作用。用阳离子改性淀粉处理后,矿井水的剩余浊度为18 NTU。Taking the mine water with high turbidity and a small amount of oil in a mine as an example,four water treatment agents,polyaluminium chloride(PAC)+polyacrylamide(PAM),cationic modified starch,anionic polyacrylamide(CPAM)and lignin,were selected for the coagulation experiment.The results showed that under the conditions of the same water quality,the stirring speed was 80 r/min,the stirring time was 5 mins,the dosage of flocculant was 20 mg/L,the standing time was 5 mins,cationic modified starch had the advantages of small dosage,fast reaction time,dense floc and the best coagulation effect,the residual turbidity of mine water was 18 NTU.
