摘　　要：碎煤加压气化废水生化出水分别用混凝剂PAC和PFC进行强化混凝处理,考察出水有机物(TOC)的去除率。结果表明,采用强化混凝工艺可有效降低水中的有机物,随着混凝剂加药量的增大,有机物的去除率升高,并且使用PFC的效果要优于使用PAC的效果。PAC和PFC分别对应不同的最优混凝水力条件,采用PFC的最优混凝水力条件为混合转速100 r/min,混合时间3 min,反应转速60 r/min,反应时间30 min;采用PAC的最优混凝水力条件为混合转速100 r/min,混合时间0.5 min,反应转速60 r/min,反应时间30 min。The experiment was carried out with the aim of study the effect of removing organic matter （TOC） after the enhanced coagulant with PAC and PFC used as treating the waste water in pressurized gasification of pulverized coal after the biological treatment. The result indicated that the organic matter in water can be reduced with the enhanced coagulant process, and the effect of the organic matter can be more reduced with the increased coagulation,and the effect of using the PFC can be better than using the PAC. The hydrodynamic conditions in the different coagulation experiment is slightly different, the best hydrodynamic conditions of the PFC coagulation is： commix rotating speed 100 r/min, commix time 3 min;reaetion rotating speed 60 r/min, reaction time 30 min. The best hydrodynamic conditions of the PAC coagulation is： commix rotating speed I00 r/min, commix time 0.5 min, reaction rotating speed 60 r/min,reaction time 30 min.
