摘要
利用碳酸钠对膨润土进行改性,探讨其改性条件及改性后膨润土对生活污水中磷的去除效果。实验结果表明,经投加6%的钠化剂、搅拌90min改性后的膨润土对校园生活污水中的总磷和正磷酸盐的去除率可达69.4%和36.8%。
The bentonite was modified by using sodium carbonate. The modification conditions and removal efficiency of phosphorus from schoolyard domestic sewage were studied. The experimental results showed that the removal efficiency of total phosphorus and orthophosphate could be up to 69. 4% and 36. 8% respectively with the total amount of sodium carbonate being 6% and stirring time being 90 minutes.
