The invention provides an immersed ultrafiltration membrane detection device. The immersed ultrafiltration membrane detection device comprises a control unit, a gas source unit, a pressure sensor and a gas inlet pipeline, the gas source unit is used for being connected with the gas inlet end of the immersed ultrafiltration membrane, the pressure sensor is arranged on a gas inlet pipeline, and the gas source unit and the pressure sensor are both electrically connected with the control unit; the control unit is used for controlling the air source unit to open or close; the pressure sensor is used for measuring a first pressure value and measuring a second pressure value after a set time; the control unit is used for receiving the first pressure value and the second pressure value, calculating a difference value between the first pressure value and the second pressure value, and judging that the immersed ultrafiltration membrane is damaged when the difference value between the first pressure value and the second
