Control method for water level of water treatment system

The embodiment of the invention provides a water level control method for a water treatment system, and relates to the technical field of water level control. The control method for the water level of the water treatment system comprises the following steps: driving a liquid level detector to enter a water pool, wherein the liquid level detector is used for outputting a signal representing the water level; the controller obtains water level data according to the water level signal and controls the water pump to start and stop according to the water level data; the controller is used for driving the standby liquid level detector to enter the water pool under the condition that the liquid level detector breaks down or the obtained water level data is abnormal. Therefore, the water pump is prevented from being affected to pump out or overflow water in the pool, and production stability is guaranteed. 本发明的实施例提供了一种用于水处理系统水位的控制方法，涉及水位控制技术领域。该用于水处理系统水位的控制方法包括驱动液位检测器进入水池，液位检测器用于输出表征水位的信号；控制器依据水位信号得到水位数据，根据水位数据控制水泵启停；
