磁化水抑垢中SO_4^(2-)浓度限值实验与探讨

EXPERIMENT AND INVESTIGATION ON THE LIMITATION OF THE CONCENTRATION OF SO 2- 4 IN THE RESTRAINT OF SCALE FORMATION BY MAGNETIZED WATER

应用动态实验，探讨了ＳＯ２－４浓度对磁化水抑垢效果的影响．确定抑垢时ＳＯ２－４浓度限值为ＣＨＣＯ－３／ＣＳＯ２－４大于２．

Through dynamic test ,the paper investigated the effects of concentration of SO 2- 4on the susceptibility of restraining scale formation. The limitation of the concentration of SO 2- 4is that C HCO - 3 / C SO 2- 4 is more than 2.2.
