Deposited sludge flushing method and device for double-layer inclined plate of sedimentation tank

The embodiment of the invention provides an accumulated sludge flushing method and device for a double-layer inclined plate of a sedimentation tank, and the method comprises the steps: responding to an opening signal of an electric valve, sending a starting signal to a flushing water pump, and enabling the starting signal to carry an initial frequency value of the flushing water pump, and the flushing pressure value of the flushing water main pipe corresponding to the flushing water pump is obtained, a target frequency value is determined according to the flushing pressure value, a frequency adjusting signal is determined based on the target frequency value and the initial frequency value, and the frequency adjusting signal is sent to the flushing water pump. The method comprises the steps of sending a starting signal to a flushing water pump in response to an electric valve opening signal, obtaining a flushing pressure value of a flushing water main pipe corresponding to the flushing water pump, determining
