The present invention is a multi-connected aerator comprising at least one cylinder capable of accumulating pool water, a plurality of venturi units mounted to the cylinder, and a gas supply unit capable of supplying gas to the two venturi units in parallel. composition. When the cylinder is installed in an aeration tank or a water tank, two or more sets of venturi units can be elastically installed according to actual needs, so that the Anvenn tube units can be sprayed with aeration bubbles in multiple directions. The utility model can fully improve the efficiency of disturbing the pool water and avoid the sedimentation of the sewage. Further, the invention can further reduce the number of aerators installed in the aeration tank or the pool, thereby effectively reducing the construction and maintenance costs.本發明係一種多聯式曝氣機，其至少由一能蓄留池水之筒體、若干安裝於筒體之文氏管單元，以及能對兩文氏管單元並聯供氣之給氣單元所組成。俾使筒體安裝於曝氣池或水池時，可因實際需求而彈性的提供兩組或兩組以上文氏管單元安裝，令該等安文氏管單元具有可多方向噴射曝氣氣泡之特點，俾充份提升擾動池水之效率，避免污水沈澱積底，再則，本發明可進一步減少曝氣池或水池安裝曝氣機之數量，進而有效降低施工及維護成本。
