PURPOSE: An air injection structure of sediment collector is provided to obtain a collector having excellent collecting capacity by commonly using the collector at various treatment basin having different depth and minimizing loss of high pressure air at the same time. CONSTITUTION: In an injection nozzle structure unit of sediment collector comprising an input part(12) formed in the lower part of main body(10) having an ordinary collecting space(11), a discharge pipe connected to the upper part of the main body(10) so that the discharge pipe is connected to the collecting space(11), and a compressor for injecting air of high pressure through branch pipe to swirl the air in the collecting space(11) so that the dispersed sediment is discharged to the discharge pipe, the air injection structure of sediment collector is characterized in that connection pipe is bindingly connected between the main body(10) formed in a semispherical shape and discharge pipe, injection nozzle(13) is connected to the outside in the upper part of the main body(10), one side of the injection nozzle(13) is upwardly extended from the lower part of the connection pipe, and a plurality of subsidiary injection nozzles(21) are formed on one side of the discharge pipe in such a way that the subsidiary injection nozzles(21) are installed upward in a length direction of the discharge pipe with being connected from the outside to the inside of the discharge pipe.
