The present invention subterranean water equipped with drum screen device relates to processing a stack of processing system, more particularly, an exshaust rocker arm pivotally mounted in the housing in a horizontal charge the lower surface of the drum screen in generations for drum screen for drum screen by a deposited inside a the collected in a collection pipe which is arranged is made aligned with a drum screen, said collection tube inside the collection tube along the longitudinal direction of number 1 is pipe is arranged, the water pipe said number 1 a plurality of injection or air nozzle number 1 along the longitudinal direction of pipe number 1 is so installed to be separated from regular intervals is, collected include a nozzle number 1 plurality of said of tube surface with the rotation of deposit through collection tube be sloped toward the of installed from drum screen equipped with subterranean water processing system relates to a stack of processing device. The present invention as described above is drum screen arranged collecting downpipe is capable of rotating the device processing a stack of the lower for drum screen by mounting a tube collected in a collection, drum screen can be used for a long time, thereby other ends of the resistors 11 in number mirror, in addition collection tube to collect and restrict device of timer strength water or air is supplied, then injection number the deposit was rotting away corresponding to the first more sanitary real estate can be conserved as the ST safely the oxidation or reduction in the state a certain..
