Abstract

The invention discloses a method for detecting welding strength of a flat filter membrane element. The method includes the following steps: S100, dividing a periphery of a first flat plate filter membrane in the flat filter membrane element to be detected into a plurality of filter membrane units arranged in sequence; S101, using a vertical tensile testing machine to detect vertical tensile forcethat is received when each of the plurality of filter membrane units is detached from a flow deflector, and recording the vertical tensile force value corresponding to each of the filter membrane units; S102, repeating the above mentioned steps, replacing the first flat filter membrane at the above mentioned step to a second flat plate filter membrane, and realizing the detection of the strength of the second flat plate filter membrane welded to the flow deflector; and S103, analyzing the vertical tensile force values of all the records, and determining whether the welding strength of the flatfilter membrane element to be detected meets the requirements or not. The method can quantitatively analyze the welding strength of the flat filter membrane element, so that the welding strength of the flat filter membrane element can be more accurately detected.

Description

technical field [0001] The invention relates to the field of flat-sheet filter membrane elements, in particular to a method for detecting the welding strength of flat-sheet filter membrane elements. Background technique [0002] Membrane bioreactor (MBR) technology is a new technology in sewage treatment and water resource reuse in environmental engineering. It is a new water treatment method that combines high-efficiency membrane separation technology with traditional biological methods, and can be widely used in municipal sewage And the treatment of various organic industrial wastewater. Among them, the membrane separation system is the main device of this new technology, and the flat sheet filter element is the key component of the membrane separation system. The flat filter membrane element usually includes a deflector and a flat filter membrane located on both sides of the deflector. The periphery of the flat filter membrane is welded to the deflector so that the perip...
