Device for biological treatment of domestic garbage leachate and stink

The invention discloses a device for biological treatment of domestic garbage leachate and stink. The device comprises a probiotic storage tank, a tank body valve, a control cabinet, a small gas monitoring station, a gas detection module, a conveying pump and an atomization device which are sequentially connected through a conveying pipeline, after the atomization device is started, the air supply device is instantaneously started under the control of the air supply device adapter, air flow from the air supply device is guided to enter the atomization device. Meanwhile, the motor controls the rotary liquid atomizer device to start to operate to convert liquid into liquid drops with submillimeter sizes to be sprayed outwards; an atomization angle adjuster mounted at the end part of the atomization device can be manually or automatically adjusted, so that the atomized liquid drops upwards or downwards guide the atomizer to accurately spray the probiotics to a target position relative to the direction of the air
