Patent number: 9845256Abstract: The object is to provide an activated sludge treatment method whereby production of excess sludge is brought substantially to zero; and a method for upgrading existing waste water treatment equipment, employing this method. The method includes a step (1) in which sludge 1 produced in a bioreactor is supplied to a waste water aeration-conditioning tank for activated sludge treatment; a step (2) in which waste water into which the sludge 1 has been mixed is subjected to aeration-conditioning to bring the oxidation-reduction potential to a positive value, and the conditioning treated waste water 1 supplied to the bioreactor; a step (3) in which released water from the bioreactor is considered to release water.Type: GrantFiled: March 7, 2012Date of Patent: December 19, 2017Assignee: JAPAN ALSI CO., LTD.Inventor: Kiyoharu Fujino
