fourthly, cleaning impurities, after the impurities are accumulated to a certain degree, driving a water outlet pipe (24) to rotate by a servo motor (21), enabling a flexible brush (42) below a transverse fixing rod (41) to rotate, cleaning the impurities on the upper surface of a circular ring filter screen (25) to a square opening, enabling the impurities to enter a containing box (40), detecting by a pressure sensor (44), sending a signal to a controller (27), controlling a starting warning lamp (47) to be turned on and a loudspeaker (48) to be sounded by the controller (27) after the impurities in the containing box (40) reach a certain weight, reminding a worker to clean, opening an electromagnetic lock (51), pulling open a rotary blocking door (50), taking the containing box (40) out, cleaning, returning the containing box (40) to the original position after cleaning, closing the rotary blocking door (50), and locking the electromagnetic lock (51), the whole working process is completed, and in the treatment process, impurities are cleaned through rotation of the flexible hairbrush (42), so that the filtering efficiency is guaranteed.
