However, after the basket grid is used for a period of time, the filtering holes are blocked by impurities in the inlet water, particularly soft impurities such as hairs and the like, and the filtering holes are easy to block and difficult to clean. When the blockage reaches a certain degree, sewage overflows from the basket grid and directly enters the equipment, so that the basket grid loses the filtering function, and the risk of pipeline blockage and membrane pollution is increased; and the basket grid can not be provided with a back washing device, and can only be manually cleaned through manual frequent operation, so that the labor input is increased, and the use efficiency of the equipment is reduced.
