Membrane washing machine

Abstract

The invention discloses a membrane washing machine, and belongs to the technical field of environment-friendly sewage treatment. The membrane washing machine structurally comprises a base, a cleaningbox, a basket, an aeration system, a circulating system, a cleaning agent filling system, a clear water filling system and an emptying system, or structurally comprises the base, the cleaning box, a lifting device, the basket, a tray, the aeration system, the circulating system, the cleaning agent filling system, the clear water filling system and the emptying system. A cleaning agent or water circulates up and down in the cleaning box through a circulation pump and an aeration pipe, so that hollow fiber membrane filaments or flat membrane sheets are in full contact with the cleaning agent andwater, and then membrane washing time is shortened. The hollow fiber membrane filaments are stacked on a grid or the flat membrane sheets are vertically arranged on a vertical concave plate, so thatthe membrane filaments are not closely attached to each other, the membrane sheets are not closely attached to each other, and the membrane filaments and the membrane sheets are in full contact with the cleaning agent and water, and a good cleaning effect is ensured.

Description

technical field [0001] The invention relates to a cleaning tool, which belongs to the technical field of environmental protection water treatment equipment, in particular to a membrane washing machine. Background technique [0002] Membrane bioreactor (MBR) technology is a new type of water treatment technology that combines activated sludge process and membrane separation process. The membrane module composed of hollow fiber membrane or flat membrane membrane module is immersed in the well of membrane bioreactor. In the oxygen pool or membrane pool, the sludge-containing water is on the surface of the membrane filament or membrane, and through negative pressure suction, the water enters the hollow diameter of the hollow fiber membrane or the inner side of the flat membrane, and the sludge is trapped in the membrane. The outer surface of the silk or membrane, the produced water flows into the produced water tank through the produced water pipe, and the sludge stays in the ae...

Problems solved by technology

[0007] 2. The effect is not good:

[0008] Membranes or membranes are often stacked in the water tank, and some membranes or membranes are placed relatively tightly, and the water containing the medicament cannot be fully soaked during soaking, which makes the soaking effect uneven and the flux of the membrane cannot be recovered well;
