麻叶处理模拟重金属废水(10000字)
摘 要：重金属废水污染给人们的身体健康带来了严重影响，本文主要研究在不同品种麻叶，不同pH（2,3,4,5,6,7,8），不同吸附时间（1h，2h，8h，12h，24h）和不同重金属离子浓度（10mg/L，20mg/L,50mg/L,100mg/L）的条件下，麻叶处理模拟重金属离子废水的效果。结果表明，在各个不同品种麻叶中，品种型号为J051的麻叶处理模拟重金属废水的效果最好，吸附率平均达到91%；随着pH值的变化，溶液过滤速度会受影响，在pH值为5时，溶液过滤效果最好，吸附率平均达到86%；随着时间不断增长，吸附率不断升高，在吸附时间为24h时，吸附率最高且平均在89%；随着重金属离子浓度的升高，吸附率逐渐降低，在重金属离子浓度最低且为10mg/L时，吸附率最高且平均在88%。

Removal of heavy metals from the wastewater with cannabina
Abstract: It is necessary to treat heavy metals from wastewater due to serious human health effects,under different varieties of cannabina, different pH (2,3,4,5,6,7,8) ,different adsorption time (1h, 2h, 8h, 12h, 24h)and different heavy metal concentration (10mg / L, 20mg / L, 50mg /L, 100mg /L ) conditiont,the removal of heavy metals from wastewater with cannabina was studied. The results showed that under different varieties of cannabina, in the leaves of hemp type J051 varieties of heavy metal wastewater leaves processing simulation works best, adsorption rate average reached 91%; With the change of the pH value, the speed of the filter solution will be affected, in pH value for five, the filter solution have best effect, adsorption rate reached 86% on average; As time constant growth, adsorption rate has been increased, for 24h, adsorption in the highest rate and average reached 89%; As heavy metal ion concentration increases, adsorption rate gradually reduced, in heavy metal ion concentration 10mg/L for the lowest and highest rate, adsorption and average in 88%.
