Advanced Wastewater Treatment System Using Effluent Electrolysis

摘要

The present invention relates to a high sewage wastewater treatment system using a semi-water electrolysis, it is intended to be introduced into the bioreactor by electrolyzing the semi-water consisting of the concentrate supernatant, dehydrator desorber, and the like.;To this end, the present invention, the suspended solids removal tank for sedimentation / separation of the solid material in the influent sewage; A bioreactor for removing organic substances and nutrients from the effluent water of the suspended solids removal tank, the electrolyzed return water and the solid-liquid separated return sludge; A solid-liquid separation tank such as a membrane or a sedimentation basin for solid-liquid separation of microorganisms from the mixed suspended solids in the bioreaction tank to obtain final treated water; A sludge treatment tank for discharging the sludge cake and the return water by treating the sludge generated in the floating material removal tank and the sludge generated in the bioreaction tank or the solid-liquid separation tank; By providing a sewage treatment system consisting of an electrolysis tank that electrolyzes the return water generated in the sludge treatment tank and sends it to the biological reaction tank, thereby effectively removing the return water containing high concentrations of organic substances and nutrients. It can increase the efficiency.;Electrolysis tank, reflux water, bioreactor, organic substance removal, nitrogen and phosphorus removal
