| 摘 要： | 化纤厂废硅藻土再生利用研究以处理腈纶废水后的硅藻土为研究对象,从废硅藻土再生利用的角度出发,用动态渗滤实验方法研究硅藻土上所吸附的主要金属离子(Na+、Al3+、Fe2+、Zn2+、Ca2+、Mg2+)的相关解吸规律及效果,并用静态浸泡实验方法研究SO42-的解吸规律效果及效果。实验结果表明:以pH=11水溶液进行动态渗滤处理,所获得的硅藻土吸附性能得到较好的恢复。

| Abstract: | Diatomite in the treatment of acrylic fibre wastewater was selected to study the recycling of deposed diatomite. Dynamic leaching experiment was conducted to evaluate the desorption rule and effect of Na+, Al3+, Fe2+, Zn2+, Ca2+ and Mg2+ absorbed deposed diatomite while SO42- was evaluated by static soaking experiment. Results showed that efficient recovery of diatomite absorption was obtained by dynamic leaching of water solution with pH of 11. |
