摘要:
针对电厂循环冷却水中生物黏泥滋生问题，研究了三种典型生物酶通过不同比例复配对生物黏泥的处理效果。结果表明，α-淀粉酶、胰蛋白酶和溶菌酶比例为2 ∶1 ∶1的复配酶对生物黏泥的去除率最高，达(30.49±1.46)%，α-淀粉酶在对生物黏泥的剥离中发挥主要作用。比例为1 ∶1 ∶2的复配酶对降低生物黏泥活性效果较好，减少率达(61.70±3.81)%，溶菌酶对生物黏泥活性减少更为关键。扫描电子显微镜（SEM）、傅里叶红外光谱（FT-IR）和X射线光谱（EDS）图像表明,生物酶是通过降解生物黏泥中的蛋白质和多糖而实现对其去除，而溶菌酶则通过灭杀细菌实现对生物黏泥活性的抑制。
Abstract:
In order to solve the problem of biological slime growth in circulating cooling water of power plants, the treatment performance of three kinds of typical biological enzymes with different mass ratio on biological slime was investigated. The compound enzyme with α-amylase, trypsin and lysozyme ratio of 2 ∶1 ∶1 had the maximum removal efficiency of biological slime, which was (30.49±1.46)%, and αamylase played an important role in the removal of biological slime. The compound enzyme with α-amylase, trypsin and lysozyme ratio of 1 ∶1 ∶2 reduced the activity of biological slime by (61.70±3.81)%, and lysozyme was important in the reduction of biological slime activity. Scanning electronic microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR) and energy dispersive spectroscopy (EDS) images showed that biological enzyme could degrade proteins and polysaccharides of biological slime so as to remove biological slime and lysozyme could inactivate bacteria so as to inhibit the activity of biological slime.
