摘　　要：采用^(60)Co-γ射线辐射合成了不同特性黏数与旋转粘度的聚二甲二烯丙基氯化铵(PDMDAAC),它与聚合氯化铝、氧化钙组合作为污泥深度脱水调理剂,相比单一采用氧化钙,可降低用药成本,并具有良好的脱水效果。Polydimethyldiallylammonium chloride with different intrinsic viscosity and rotary viscosity is synthesized by ^(60)Co-γ ray radiation.It is used in combination with polyaluminum chloride and calcium oxide as a deep dehydrating agent for sludge.Compared with the single use of calcium oxide,the combination of sludge conditioner can reduce the cost of chemical agent,and the dehydration effect is better,and It is advantageous to the lake bottom sludge recycling use.
