Summary: | The utility model provides a low-resistance, short-flow and anti-pollution flat plate membrane element. Flow guide grooves are formed in the front and rear side faces of a supporting plate respectively; the flow guide grooves are connected with water outlets; the water outlets are formed in positions at the periphery of the supporting plate; one layer of flow guide filtering cloth is arranged on each of the front and rear side faces of the supporting plate in a covering and bonding manner; and one layer of micro-porous filtering membrane is arranged on the outer side of any one layer of the flow guide filtering cloth in a covering and bonding manner. A plurality of island-shaped convex parts are arranged on the front and rear side faces of the supporting plate respectively; and each flow guide groove is composed of a gap between two island-shaped convex parts. The supporting plate has penetration holes. An edge frame is arranged at the periphery of the supporting plate; and the peripheries of the flow guide filtering cloth and the micro-porous filtering membranes are connected with the edge frame in a welding manner. According to the low-resistance, short-flow and anti-pollution flat plate membrane element, the water flow resistance is reduced and a water collection flow path is shortened by using the flow guide grooves, so that the energy consumption is reduced and the pollution to the filtering membrane, caused by sewage biological treatment, is reduced; and meanwhile, the use intensity is kept and the online washing is easy to carry out. |
