摘　　要：将煤泥水在微波场下做预处理,探讨微波能量场对煤泥水自然沉降以及与絮凝剂协同作用沉降效果的影响,结果表明,预处理试样自然沉降改善明显,与絮凝剂的协同作用可将最佳药剂量从1.25 m L降低到0.75 m L,达到了降低药耗、提高沉降速度的目的。A microwave radiation pretreatment was, adopted to explore the effect of natural sedimentation and flocculation in microwave field. The results show that the sedimentation efficiency were significantly improved by a microwave radiation pretreatment, the amount of flocculating agent reduced from 1.25 mL to 0.75 mL, which can achieve the purpose of lower flocculating agent consumption and higher sedimentation efficiency.
