<p>PURPOSE:To provide a sulfur-recycling system suitable for the recovery of resources, disposal of waste liquid, recovery of energy, etc. by utilizing the heap of garbage, construction scraps, etc. CONSTITUTION:A proper output is obtained by an arbitrary combination of ( I ) a system consisting of the system (1) for reducing sulfur oxide such as sulfuric acid, the system (2) for oxidizing sulfides such as hydrogen sulfide, the system (3) for oxidizing sulfur oxides such as sulfate radical, and the system (4) for separating sulfur oxides, etc. such as sulfate radical, etc., (II) an input and output system consisting of the representative materials a-h of the process, and (III) the system of the material flowing along the direction of the arrows [(A) and (E) are S<-> and S<-2> such as H2S, NaHS, Na2S, etc.; (B) is elemental sulfur; (C) and (F) are SO4<-2> or S2O3<-2>; (D) is SO4<-2> or CaSO4, FeSO4, etc.].</p> |
