WATER TANK EQUIPMENT AND RECLAIMED WATER SUPPLY APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a water tank unit capable of preventing the accumulation of a solid contained in received waste water and a reclaimed water supply apparatus employing the same. SOLUTION: The receiving chamber 30 arranged in the water collecting chamber 20 of a tank body 10 has a bottomed cylindrical shape and a large number of openings 32 are provided to the upper side surface part thereof. An inflow pipe 34 is extended so as to inject waste water into the receiving chamber 30 and an outflow pipe 36 is connected to the upper part of the receiving chamber 30. An air lift 42 is operated in connection with the lowering of the water level in a storage chamber 2 to transfer the water in the water collecting chamber 20 to a biological filter bed chamber 22. The water biologically treated by the biological filter bed 44 in the biological filter bed chamber 22 flows in the upwardly turned pipe part 52 of a filtering and sterilizing cylinder 50 through an overflow pipe 48 to be filtered by a ceramic bed 54 and the filtered water is subsequently electrolyzed and sterilized in the vicinity of an electrode 64 to flow in the storage chamber 24 from an opening 62 to be sent out to a demand place through a reclaimed water supply pipe 70.
