RECLAIMED WATER SUPPLY APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a reclaimed water supply apparatus constituted so as to facilitate the maintenance of electrodes for electrolytic sterilization. SOLUTION: An air lift 42 is operated in connection with the lowering of the water level in a storage chamber 24 and the water in a water collecting chamber 20 is transferred to a biological filter bed chamber 22. The water biologically treated with the biological filter bed 44 in a biological filter bed chamber 22 flows in the upwardly turned pipe part 52 of a filtering and sterilizing cylinder 50 through a flooding pipe 48 to be filtered by a ceramic bed and this filtered water is subsequently electrolyzed and sterilized in the vicinity of an electrode 64 to overflow from an opening 62 to the storage chamber 24 to be sent to a demand place through a reclaimed water supply pipe 70. The electrode 64 is integrated with a support plate to be made accessible to the upwardly turned pipe part 58 of the filtering and sterilizing cylinder 50 from above.
