<p>PURPOSE: To fix pollutant by crushing solid materials, adding liquid waste to the crushed materials to obtain a pasty mass, adding pulverulent calcium carbonate, silicium oxide and aluminum and iron oxides to the pasty mass, and incinerating the mixed mass. CONSTITUTION: The solid portions of waste materials are crushed and ground to a granulometry of under 5 mm. After the addition, if applicable, of liquid waste to the granulometry to obtain a pasty mass, an additional material consisting of pulverulent calcium carbonate, silicium oxide and, possibly, aluminum and iron oxides having under 50μm average particle size is added to the pasty mass to be incinerated at about 750 deg.C to 1350 deg.C. The additional material is changed depending on the type and character of waste materials to be incinerated and a concentration of the final effluent is adjusted to formula I. Thus, high endothermal reaction is occurred by deoxidizing limestone with the inexpensive additional material in the waste incineration treatment to combust a larger amount of wastes at a lower temperature. The burnt residue is insoluble and inert solids.</p> |
