摘　　要：电力工业制水用水过程中产生的垢样与污泥主要成分为Mg^(2+)、Ca^(2+)、Fe^(2+)、Fe^(3+)等。为控制垢样产生,文章设计合成了一类聚(甲基丙烯酸甲酯)-(二甲基丙烯酸乙二醇酯)共聚物P(MMA-co-EGDMA)纳米微球,并对比考察了P(MMA-co-EGDMA)纳米微球、线性聚甲基丙烯酸甲酯(PMMA)、商业化钙镁螯合树脂随温度变化对Mg^(2+)、Ca^(2+)的吸附曲线,及其对产生的垢样污泥总量与成分的影响。实验结果表明,P(MMA-co-EGDMA)纳米微球可用于电厂用水过程中控制垢样污泥的产生,能够有效降低钙镁垢样污泥总量,有利于系统正常安全运行。The main sources of scale and sludge generated during the water production process in the power industry are Mg^(2+),Ca^(2+),Fe^(2+),Fe^(3+),etc.In order to control the generation and composition of scale samples,a type of poly(methyl methacrylate)-(ethylene glycol dimethylacrylate) copolymer nanospheres (P(MMA-coEGDMA)NPs) were designed and synthesized in this paper.The effects of temperature on the adsorption curves of Mg^(2+)and Ca^(2+),as well as the total amount and composition of scale generated sludge,were compared and investigated in P(MMA-co-EGDMA)NPs,linear poly methacrylate (PMMA),and commercial calcium magnesium chelating resin.The experimental results indicate that P(MMA-co-EGDMA)NPs could be used to control the generation of scale like sludge during the water use process in power plants,effectively reducing the total amount of calcium magnesium scale like sludge,which is beneficial for the normal and safe operation of the system.
