Abstract
This invention refers to method for cleaning sewage and can be used for cleaning sewage from heavy metals. Technical result is achieved in simplifying and cheapening process. The method provides for the cleaning sewage by electro-flotation simultaneously with electro-coagulation, the current intensity for electro-coagulation being 50-100 A the voltage 15-30 V, anode current density 100-200 A/m2, the volume current density 0,25-0,5 A/L with the use of aluminium anodes whereas for electro-flotation the current intensity is 20-25 A,the voltage is 8-10 V, the surface current density is 70-80 A/m2, the volume current density is 0,1-0,15 A/L with the use of insoluble anodes. 1 tab.
