One kind have Shui nationality high-density breeding water automatic sewage,The pressurization of dirt separation decontaminates oxygen supply device,Including an aquaculture pond (or cylinder,Slot),First treatment trough and second processing slot,First treatment trough middle section is several layers of sewage permeation process layer,And the first treatment trough is divided into upper sump and lower sump by the sewage permeation process layer,A dirt collection bin and a water inlet pipe are set on what in sump,Water inlet pipe outer end is protruded into aquaculture pond,Water inlet pipe inner end connects a hollow water polluting matter separating pipe； Lower sump is communicated with the lower flume of second processing slot,The second processing slot middle section is several layers of sewage reverse osmosis process layer,And second processing slot is divided into upper flume and lower flume by the sewage reverse osmosis process layer,Aeration machines can be set according to actual needs in what lower flume,Booster aerator is equipped in upper flume,Booster aerator will then enter in aquaculture pond by filtering and the clean cultivation recirculated water re-injection of oxygen supply； The output end of another what booster aerator can one pressure inlet of branch connect to the water inlet pipe of the first treatment trough； By aquaculture pond,Atmospheric pressure caused by the differential water pressures and aeration machines and booster aerator of first treatment trough and second processing slot,It must promote the sewage in aquaculture pond and precipitating dirt that can easily be sucked by water inlet pipe,The water polluting matter separating pipe connected using water inlet pipe inner end carries out being automatically separated for sewage and dirt with the larger hydraulic pressure that collects in pipe and powerful flow velocity,And the waterfall gas of the filtering and second processing slot through the first treatment trough,Filtering and
