沸石对废水中铵离子交换特性的实验研究

his article refers to the domestic and foreign related literature search zeolite to the waste water in the ammonium ionic exchange characteristic experiment, through the static testing, the dynamic testing and the regeneration experimental study natural has sent the zeolite slanting to the waste water in the ammonium ion exchange characteristic, the reproductive properties as well as the influencing factor. The test result indicated: Sends the zeolite slanting to ammonium ion static saturated adsorptive capacity 3100 mg/100 g; When the ammonium ion concentration is 35 mg/L, the dynamic saturated adsorptive capacity is 2200 mg/100 g, the choice load ratio is 3:7 NaCl+NaOH intermixture takes sends the zeolite the regenerant to be possible slanting to carry on three redundant regeneration uses, the effective life may reach above 140 h. Therefore sends the zeolite to use in slanting processing including the ammonium ion waste water has the broad practical prospect.
