The first liquid level sensor 13 and the second liquid level sensor 22 are both in signal connection with a master control device. The main control device receives signals of the liquid level sensor to obtain the information of the amount of the waste water accumulated in the sedimentation tank 10 and the recovery tank 20, and further analyzes and processes whether the transfer pump 12 or the waste water pump needs to be controlled to discharge the waste water. The main control device replaces manpower to realize automatic control of wastewater discharge, so that the wastewater treatment device is more stable and efficient in operation.
The first wastewater pump 31 and the second wastewater pump 32 are both provided with sensing devices (not shown), the sensing devices are connected to a main control device, and the two sensing devices respectively sense whether the states of the first wastewater pump 31 and the second wastewater pump 32 are normal or not and transmit information to the main control device. The front end and the rear end of the first wastewater pump 31 and the second wastewater pump 32 are both provided with valves 33 connected to the main control device, and the main control device controls the opening and closing of the valves 33. The two sensing devices monitor in real time and respectively feed back the states of the two waste water pumps to the main control device, when one of the waste water pumps is stopped due to fault maintenance or cleaning maintenance, the main control device can automatically control the valve 33 to close a pipeline leading to the waste water pump, and then the other waste water pump is started to discharge waste water. The automatic monitoring and control is matched with a spare double waste water pump to ensure that the waste water treatment device can continuously work, and the waste water discharge capacity is more reliable.
