摘要
将污水厂排出的剩余污泥添加粘土和矿渣在不同的温度下烧制成滤料,研究在不同投加量、震荡时间、pH值、离子初始浓度等条件下滤料对Ni2+的吸附性能。通过分析,吸附性能在一定范围内分别随投加量和震荡时间的增加而增加,在投加量达到9 g、吸附时间达到110 min时吸附平衡。在弱酸到中性条件与较低Ni2+初始浓度下吸附性能较优。
The haydite was mainly manufactured by sludge from urban sewage treatment plant.Clay and slag were added in it and the haydite was sintered under various temperatures.Under different initial weight of the sludge haydite,stroke time,initial pH,initial concentration,the adsorptions of Ni2+ were studied.Through the analysis of the statistics,at some extend,the adsorption quantity would improve with the increase of stroke time and initial weight of the haydite.The absorption equilibrium achieved after only 110 min oscillation or over the total amount of haydite about 9 g.Weak acid,neutral condition and low initial concentration of Ni2+ was benefit to the adsorption.
