SEWAGE REGENERATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a sewage regeneration apparatus which treats sewage and allows the recycling of the purified water obtd. by the treatment in specific applications. SOLUTION: The sewage discharged from a washing tank 3 of a washing machine 1 flows into the treating vessel 2 of the sewage regeneration apparatus D1 . Activated sludge is put into the treating vessel 2 which is provided with a filter membrane device 4. The suction header 7 to the filter membrane device 4 is connected to a suction pump 8 via a suction pipe 9. Electrodes 14, 15 consisting of iron are hung and arranged at the treating vessel 2. The electrodes 14, 15 are immersed into the sewage in the treating vessel 2 and elute the iron ions for removing the phosphoric acid in the sewage by electrolysis. A tank 12 stores the purified water sucked by the suction pump 8. A supply pump 18 which pumps up the purified water in the tank 12 and supplies the water to the washing tank 3 is disposed at the bottom of the tank 12.
