Note that one of the major drawbacks limiting the extensive application of the adsorption materials, in particular, organic clay, in the treatment of the wastewater is their regeneration and reuse after adsorption of the pollutant. 注意到常见的吸附材料,特别是广泛应用于地下水污染处理的有机粘土,限制其应用的一个主要瓶颈是处理后的材料再生及回收困难。
The experiments for wax and lube oil recovery from waste clay in oil refining industries by surfactant solutions, and for regeneration and comprehensive utilization of dewaxing or deoiling waste clay have been conducted. 对表面活性剂溶液回收炼油厂废白土中的石蜡和润滑油脱蜡脱油废白土的再生活化、综合利用进行实验研究。
As a result of a huge difference with the contain of clay and LOI between the mixed used sand and the core sand, the general method can not meet the requirements of regeneration. 由于混合旧砂的含泥量、灼减量与制芯用砂的要求相差巨大,一般的再生方法难以满足要求。
