The idea which it sees with the thing, more the crabs under upper three width description below from the labor pains system for in compliance with the air which is discharged from the width basis inside scandal flowing, induce with the circulating derivative in about width system and five waste waters which are accommodated on the width basis inside uniformly, in order to circulate, and efficiency of width system on a large scale it is a thing in about the circulation width system it will be able to prevent the fact that the improvement percentage sludge reaches enemy layer. The idea which it sees in order to accommodate five waste waters, is affixed in the width basis which is formed and the minute description width basis inside and there is to width system where the labor pains system which discharges an air is included, minute description labor pains system (25) from the bubble which is discharged it flows and induces the circulating derivative for the minute description width basis (on 10 and 12) insides to be affixed, in order for the minute description circulating derivative, in order to induce the bubble which is discharged minute description labor pains system (25) from minute description labor pains system (25) from (38) comes to lower part, the bubble which flows to be induced with the influx where the bubble which is discharged flows and, the fluid to be discharged, top(27) circulating induction vice-is formed re-(30 ~ 35) comes with outflow; Minute description circulating induction vice-re-(30 ~ 35) the minute description width basis (it fixes on 10 and 12) insides the fixation means for; It includes and it is composed the fact that with feature.
