Referring to fig. 4, in practical use, since it is difficult to achieve a good backwashing effect of the ceramic membrane filter tube 7 by using a constant pressure water source, at present, pulse water pressure is mainly used, so as to achieve an action similar to flushing the inside of the ceramic membrane filter tube 7, thereby obtaining a good cleaning effect. However, the cost is high when the pulse pump is directly used for supplying water to the purified liquid outlet pipe 13, and the water is output in a pulse mode, so that the situation that water continuously enters after the pulse and before the next pulse, and accordingly impurities washed by the pulse cannot be brought out cannot be realized. The applicant therefore made the following improvements:
