摘　　要：利用膨润土的吸附能力,对含N(iⅡ)的工业废水进行吸附处理情况进行了研究。用膨润土原土和活化土吸附剂处理含N(iⅡ)水样,研究膨润土在不同试验条件,如吸附剂用量、处理时间等对N(iⅡ)的吸附率的变化。结果表明,无论是原土还是活化土,吸附量10%为最佳,活化土处理效果比原土的去除率高约3%;高温焙烧可以改变膨润土的吸附性能,提高吸附率,最佳焙烧时间为30 min;处理时间以60 min为最好。Treatment of containing Ni（Ⅱ）wastewater by using bentonite adsorptive capacity was studied.Nickel containing wastewater was treated by original bentonite and activated bentonite respectively.Effects of different conditions including adsorbent dosage,treatment time,etc.on adsorption rate of Ni（Ⅱ）were discussed.The experimental results show that adsorption rate of activated bentonite is higher than that of original bentonite by 3%,high-temperature calcination can change adsorption property of bentonite and improve adsorption rate,the best calcination time is 30 min,the best treatment time is 60 min.
