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.
