This contribution presents the possibility of application of natural sorbent (Transcarpathian clinoptylolite (KL)) for immobilization of selected heavy metals in the sewage sludge. The influence of ion-exchange parameters (e.g. time, amount of zeolite) were discussed. Process of immobilization was performed using a static method (Batch). It was found that best possible conditions for immobilization of heavy metal ions were as follows: zeolite fraction 0.7-1.0mm, 5h of shaking, zeolite/sewage sludge ratio 2/98.
本论文介绍了使用天然吸附剂(外喀尔巴阡斜发沸石(KL))固定污水污泥中特定重金属的可能性。讨论了离子交换参数(如时间、沸石用量)的影响。固定过程采用静态方法(分批法)进行。结果发现,固定重金属离子的最佳条件如下:沸石粒度为0.7 - 1.0毫米,振荡5小时,沸石/污水污泥比例为2/98。
