摘　　要：以天然钙基膨润土为原料,钠化后用钼酸铵改性,制得钼酸铵改性钠化土(钼酸铵改性土),应用于啤酒废水的处理。结果表明,最佳处理条件为:投土量20g/L、pH为4、搅拌时间为7min、离心时间为10min。该条件下,COD去除率可达到93.39%。After Ca-bentonite was changed into Na-bentonite, ammonium molybdate was used to modify bentonite and ammonium molybdate-modified bentonite was prepared. The modified bentonite was used for beer wastewater treatment and COD removal rate could achieve 93.39 % under the following conditions： the use level of modified bentonite was 20 g/L, pH value was 4, 7 min stirring and 10 min centrifugation.
