【摘要】 为解决重金属废物和其他非金属危险废物对环境的污染问题,采用水泥固化为主药剂稳定化为辅的综合处理技术对其进行稳定化/固化处理,以达到其最终处置所需要求。首先,经固化和浸出试验确定每批废物实验块的基本配比。然后,将可直接固化的危险废物和回转窑焚烧炉的飞灰,按配比加药剂稳定且用水泥固化。为保证固化块的强度和提高填埋场的服务年限,对基本配比系统按工艺流程采用控制室集中控制,对其计量-投料-搅拌-出料生产过程实现自动控制,而其他设备则采用现场控制。该技术已应用到多个工程中去,取得良好的效果。更多还原

【Abstract】 To solve with heavy metal and non-metal pollution to environment,it is suggested to use cement for solidification and chemicals for stabilization for final disposal,firstly basic mixing ratio is obtained from solidification and infiltration experiments,then hazardous waste is stabilized and solidified together with rotary kiln fly ash based on the optimal mixing ratio.The optimum chemicals mixing ratio is under central control to ensure the solidification strength thus prolonging the service life of landfill,and the whole process including measure,input,stirring and output is automatically controlled while equipment is controlled on site.This treatment process has been put into use and proved effective in many hazardous treatment projects.更多还原
