The ultrafiltration clear liquid enters the clear liquid storage tank. Since ultrafiltration realizes mud and water separation, the sludge concentration in the biochemical reactor can reach 15-30g / L, which can easily cause clogging of the membrane tube, affect the normal processing volume of the leachate, increase the pressure of the membrane in a short time, and increase the load-bearing capacity of the membrane.

The above-mentioned scheme solves the problem that the existing unclogging method mostly uses a combination of normal pressure tap water and a hose 107 for unclogging, which has low work efficiency and poor unclogging effect. It can be understood that the above-mentioned scheme can be used in mobile device scenarios, and the water tank 101 can also be placed through the bottom plate 111.

When the user needs to move the device, he can push the push rod 112.

[0022] In this embodiment, the water tank 101 is used to store water, so that the device does not need to have a fixed direct water supply on site.

When the user needs to move the device, he can push the push rod 112.

[0026] Finally, the solenoid valve 114 is connected to the hose 107 and is located on one side of the hose 107. The protective shell 115 is detachably connected to the water tank 101 and is located on the outside of the lithium battery 103. The solenoid valve 114 is used to individually control the opening and closing of each hose 107. The protective shell 115 is used to protect the lithium battery 103 to prevent the lithium battery 103 from being affected by a humid environment during water storage.

[0027] When using the tubular membrane dredging device of the utility model, the water tank 101 is used to store water so that the device does not need a fixed direct water supply on site.
