[0033] When using the sewage sampling and collection device in the sewage treatment process, first connect the device to the power supply to put the device into working condition. According to the requirements of sewage sampling depth, the controller 4 controls the drive motor 204. When the drive end of the drive motor 204 rotates, it drives the drive rod 205 to rotate.
