A liquid mixing, suction, pumping apparatus is provided to control an amount of air to an optimum level by allowing a cashing to be maintained in a negative pressure state. A liquid mixing, suction, pumping apparatus includes a high-pressure water feeding pipe(130) connected to a cashing(110). A nozzle(130a) is coupled to the cashing(110) in order to spray rectified water to a discharge pipe(180) at a high speed. An air feeding unit(140) is provided to feed an optimum amount of air to the cashing(110). The air feeding unit(140) includes a first pipe(141), an air tank(142), and a compressor(144). The first pipe(141) is used for introducing ambient air to the air tank(142). A second pipe(143) is provided to feed air from the compressor(144) to the air tank(142). |
