摘　　要：通过单因素实验和正交实验,考察了再生水回用过程中,水质对回用系统结垢的影响。结果表明,Ca2+、HCO3-、PO43-和温度是导致冷却水系统结垢的4个最重要因素,NH4+-N对冷却水系统结垢表现出一定的抑制作用。Through the single factor tests and orthogonal tests,a study was performed to investigate into the effect of reclaimed water quality on scale deposit in circulation cooling water.The results demonstrated that Ca2＋、HCO-3、PO3-4 and temperature were the most important factors resulted in scale deposit,while NH＋4N could restrain it.
