In the present invention, a drain pump is provided in a drain tank for generating bubble water to facilitate discharging of undissolved plain water in the tank, and a bubble nozzle is provided on the side of the outlet port to provide a non-The present invention relates to a control system for a micro bubble generator which enables the system to be operated only by one button operation so that the number of bubbles can flow out without interruption.In order to achieve the above object, according to the present invention, there is provided a water treatment system including a tank for storing water introduced through a water inlet / outlet pipe connected to a water inlet and an inlet pipe, The microbubble generator control system is connected to the lower end of the tank 20 through a water outlet 26 and an outflow pipe 27 and allows the bubble water to flow through the water shutoff valve 28, The drain pump 31 is installed in the drain pipe 30 at one side of the tank 20 and operates through the drain valve 31 so as to discharge the undissolved general water or low concentration bubble water in the tank 20 32 A vacuum release valve 33 installed at one side of the tank 20 for releasing a vacuum formed inside the tank 20 when discharging low-concentration bubble water or ordinary water in the tank 20 A micro bubble is selectively added to the undissolved general water or the low concentration bubble water in the tank 20 which is installed in the drain pipe 30 where the drain pump 32 is installed and which is discharged through the drain pump 32 A micro bubble nozzle (40) capable of providing a micro bubble A PCB substrate 10 for controlling the operation of the intake shutoff valve 23, the drain valve 31 and the drain pump 32, the vacuum release valve 33, the shutoff valve 27 and the microbubble nozzle 40, 본 발명은 버블수 생성을 위한 드레인 탱크에 드레인 펌프를 설치하여 탱크에서 용해되지 않은 일반수의 배출이 용이하도록 함은 물론 출수구 측에 버블노즐을 설치하여 용해되지 않은 일반수 또는 농도가 낮은 버블수의 배출 상태에서도 버블수가 출수되도록 함으로써, 버블수가 끊김 없이 출수될 수
