摘要
采用透射电镜和X-射线衍射分析技术,观察了不同目数固体废物试样表面形貌,测定了元素的百分含量,比较了晶形结构,井结合超声波浸出毒性试验的分析结果,对固体废物试样的粉碎程度进行了深入探讨。结果表明,在我国,目前,固体废物试样的粉碎程度以40～60目为宜。
Using Transmission Electron Microscopic and X-Ray Diffraction Spectrometric techniques, the sur face states, percent concentrations and crystal structures of solid wastes samples with different meshes were measured. The effects of sample particle size on these parameters were discussed according to the results of leachate toxicity tests, which were obtained by ultrasonic extraction method. It was concluded that the particle size of the sample of solid waste should be 40 to 60 meshes at present in China.
