Abstract | The invention discloses a method and device for electrochemically treating sewage with low-concentration carbon sources and super-high concentration ammonia nitrogen with microorganisms. The method includes the steps that under the condition that free or only a small quantity of carbon sources exist, high-concentration ammonia nitrogen sewage is treated with the electrochemistry biological denitrification method, ammonia nitrogen pollutant is converted into harmless nitrogen, operation is easy, secondary pollution is avoided, the ammonia nitrogen content of the sewage is up to the standard, and the sewage can be safely discharged; the sewage pretreated by a grating and grit chamber enters an aerobic electrode chamber, a bacteria nitrifying membrane or sludge particulates are subjected to a nitratlon reaction through oxygen generated by electrolyzed water, and ammonia nitrogen is removed; the sewage enters an anaerobic/anaerobic electrode chamber through an isolation pond, a bacteria denitrifying membrane load |
