Ozonation combined with electrolysis of night soil treated by biological nitrification-denitrification process

摘要

abstract_textpOzonation combined with electrolysis with a two- compartment electrolytic flow cell was developed and its applicability to ammonia nitrogen (NH4+-N) and total organic carbon (TOC) removal in effluent from a night soil treatment facility was discussed. The developed flow cell with an anion exchanged membrane as a separator was effective to remove NH4+-N by electrochemically generated chlorine and TOC by hydroxyl radical generated via cathodic reduction of ozone. Total nitrogen (TN) removal efficiency under the optimal condition reached to 75 and TOC removal efficiency maximally reached to 47./p/abstract_text
