The present invention provides a method of controlling a washing machine and a washing machine, wherein the washing machine includes a first drain pump (5) installed between the washing tub (1) and the filter membrane part (12). The first drain pump 5 pumps the water in the washing tub 1 to the filtration membrane component 12 and filters the filtration membrane component 12 so that the water level in the inlet chamber of the filtration membrane component 12 is not higher than the lower edge of the waste water outlet, / Reduction of washing water quantity due to discharge of rinse water is prevented. Since the first drain pump 5 uses a low-head pump, the water in the filtration membrane component 12 constantly moves during the filtration process, so that the contaminants on the filtration membrane / hollow fiber membrane surface are washed away, And noise can be reduced. Further, the water surface in the filtration membrane component 12 continuously fluctuates, and the wastewater in the filtration membrane component intake chamber is continuously overflowed by the waste water outlet. |
