The high-
salinity wastewater treatment device comprises a bottom plate, a cleaning
machine is installed at the position, close to the front side, of the top of the bottom plate, the cleaning
machine is located at the position, close to the left side, of the front side of the bottom plate, a cleaning fluid spraying mechanism is arranged in the cleaning
machine, and a
drying machine is fixedly connected to the position, close to the rear side, of the right side of the bottom plate. According to the cleaning device for the RO membrane, through mutual cooperation of a grooved wheel, a belt, a small motor, a limiting plate, a
crank, a rotating plate, a clamping block, a bearing plate, a side plate, a spring, a placing plate, a supporting plate, a collecting box, a discharging
pipe and other parts, when the RO membrane needs to be cleaned, the RO membrane can be firstly borne, and then the RO membrane can be cleaned; when the weight of the RO membrane exceeds a normal numerical value of more than three kilograms, the weight of the RO membrane can exceed the bearing limit of the spring, so that the bearing plate moves downwards and the trigger is started, and the trigger can start the cleaning fluid spraying mechanism to deeply clean the current RO membrane.
