Film column cleaning control method, apparatus and system thereof, and sewage treatment apparatus

The invention relates to the technical field of sewage treatment, and discloses a film column cleaning control method, an apparatus and a system thereof, and a sewage treatment apparatus. The cleaning effect of a film column is optimized, so the cleaning cost is saved, and the service life of the film column is prolonged. The cleaning control method comprises the following steps: acquiring the accumulative cleaning frequency of the film column, the accumulative cleaning time of the film column and the conductivity of inlet raw water; determining the fouling grade of the film column according to a corresponding relation between each of the accumulative cleaning frequency of the film column, the accumulative cleaning time of the film column and the conductivity of the inlet raw water and the fouling scale of the film column; and determining the cleaning executing time, the cleaning cycle frequency and the cleaning coefficient of current-time cleaning of the film column according to the corresponding relation between each of the accumulative cleaning frequency of the film column, the accumulative cleaning time of the film column and the conductivity of the inlet raw water and the fouling scale of the film column.
