This invention features that before electrolyzing sewerage, a coagulative agent for electrolysis with ferric chloride as its cheif ingredient is dumped into the sewerage and decolorization separating ferric and ferrous ions are attained by adding hydrated lime into the electrolyte. A specially designed electrolytic tank is used for said processing. After the treatment, for the industrial sewerage, the separational rate is 92-96% with CODCr; 90% BOD5. For treating 1 ton of sewerage, cost of electricity is 40-50% lower than the ordinary electrolytic process. Dualcoagulation electrolytic process can be adopted in the dyeing and printing, medical service, electroplating, and foodstuff industries for sewerage disposal. |
