Decanter for a Sequencing Batch Reactor of Middle or Large-Sized type

摘要

The present invention relates to a symbol water discharge device for a continuous batch reactor of medium and large size, in the reaction tank 100, a plurality of guide rails 10 arranged in parallel to each other is standing upright; Buoy 21 is slidably penetrated through the plurality of guide rails; On the inner side of this buoy, a discharge tank 18 having a discharge compartment 17, which is hermetically partitioned, is associated with the buoy 21; At the bottom of the discharge tank 18, a plurality of outlets 15 are formed at a predetermined interval from each other, and an inlet 12 is formed at a predetermined interval with respect to the plurality of outlets 15. ; One end of the plurality of stretchable bellows tubes 11 is fluidly connected to the plurality of outlets 15 so that the inside of the discharge chamber 17 and the plurality of bellows tubes 11 are circulated. The other end of each bellows tube 11 is fluidly connected to the other end of the said discharge tank 200 side and the some transfer pipe 19 which the one end distribute | circulates; An inlet (12) is provided with an opening / closing plate (13) connected to the opening / closing means (40) to selectively open and close the inlet (12) at the bottom of the discharge tank (18); Here, the inlet 12 is arranged at a predetermined depth on the surface of the symbolic water in the reaction tank 100.
