The column type membrane component which is commercially used at present is that a bundle of hollow fiber membranes or membrane tubes are packaged in a round tube (membrane shell) in a pouring sealant or mechanical compression mode, the hollow fiber membrane mesopores are called tube passes, and the space between the outer surfaces of the hollow fiber membranes and the membrane shell is called shell passes. For an external pressure type column type membrane module, stock solution enters a membrane module shell side, substances with the size smaller than micropores on the surface of the membrane enter a tube side through the membrane to become permeate, substances with the size larger than micropores on the surface of the membrane are trapped in the shell side by the membrane to become concentrate, and therefore a stock solution is separated into permeate and concentrate in a membrane separation process.
After the column membrane module is used for a certain period of time, the column membrane module needs to be cleaned. In the process of membrane cleaning and mud discharging, water, gas or chemical medium is injected into the lower end socket cover of the membrane module to clean and regenerate the membrane wires, and the cleaned pollutants are discharged out of the module shell side.

The hollow fiber membrane or capillary membrane is arranged in the inner cavity of the filter in a weeping manner, namely the bottom end of the membrane is closed and freely sags, and the top end of the membrane is fixed in the inner cavity of the filter through the packaging resin. This configuration allows for a larger volume of concentrate to be contained in the filter interior cavity than an internal pressure filter, which can hold more trapped contaminants. However, the pollutant is discharged along with the concentrated solution from the gas-liquid outlet at the upper end of the component in the mode of discharging the pollutant in the technical scheme, so that the pollutant with high density is easily accumulated at the bottom of the component and cannot be discharged, and the pollution discharge is incomplete.

As shown in fig. 6 and 7, the rotary shaft is connected to the upper part of the check valve plate 22, and the check valve plate 22 is closed by gravity. When the check valve plate 22 is closed, the upper surface of the check valve plate is flush with the inner conical surface of the bushing 2. By arranging the one-way valve plate 22 capable of being closed automatically, the one-way valve plate 22 can be automatically conducted when the medium is added from the diversion inlet 11, and when the medium containing pollutants in the shell side of the membrane assembly is discharged from the diversion outlet 12, the one-way valve plate 22 is closed automatically, so that the medium containing the pollutants is prevented from flowing back into the medium flow channel 5 through the through hole 21.
