Abstract

A filtering machine membrane component is characterized in that the preparation method of the machine membrane is as follows: filaments are sequentially and closely wound and fixed on a supporter with a plurality of holes; little wire spacing of the filaments is used for trapping particles in liquid phase. The preparation method of multilevel membrane component is as follows: different machine membranes are assembled together according to the large to small wire spacing, thus realizing step filtering. The membrane component prepared by the invention has high filtering precision, high infiltration capacity and excellent performance of cleaning and recovery. In addition, the membrane component has simple technique, high intensity, and is resistant to rusty and easy to clean.

Description

technical field [0001] The invention relates to a filter mechanical membrane module, which belongs to the technical field of membrane separation. It mainly uses the mechanical retention of the membrane to filter and remove particulate matter and suspended matter from the liquid phase. This technology can be used in various fields of industrial and agricultural production and social life, and is mainly aimed at the solid-liquid separation technology in the water supply and drainage industry. Background technique [0002] In recent years, membrane treatment technology has been widely used in the field of filtration and separation. At present, the commonly used membrane materials include polymer membranes, metal membranes, ceramic membranes, zeolite membranes, etc. The film-making process mainly includes phase inversion method, sintering method, deposition method, sol-gel method, thermal decomposition method, etc. However, the manufacturing process of most membrane materials...
