蜂窝煤渣对磷吸附特性探讨
|
摘要
该文研究了蜂窝煤渣在不同吸附时间、水体pH值、蜂窝煤渣用量和磷初始浓度等条件下,对水体中磷的吸附规律。结果表明,随着反应时间的延长,溶液中磷的去除率提高,60min左右可以达到吸附平衡;pH值对溶液中磷的去除率有一定影响,但不是很明显;蜂窝煤渣用量越多,磷的去除率就越高,但用量达到1g/100mL以后,去除率的增加就不显著;蜂窝煤渣对磷的去除率一般可以达到90%以上,因此,蜂窝煤渣作为废水除磷吸附剂具有很好的开发前景。
The absorption law of honeycomb-cinde for phosphorus was studied under the condition of different time,water pH,zeolite amount and initial phosphorus concentration.Results showed that with the extension of reaction time,the removal rate of phosphorus increased.The absorption equilibrium could be achieved about 60 min.pH could effect the phosphorus removal rate but only a little.The more honeycomb-cinde was used,the higher was the removal rate of phosphorus.There was no significant increase of removal rate when 1 g of honeycomb-cinde per 100 ml water was used.The removal rate of honeycomb-cinde on phosphorus could be above 90% generally.
