1. , a kind of treatment process of super-purified water, it is characterized in that:

  • adopt the program of the level Four processing of low-pressure process to come water is carried out purifying treatment, the program that the level Four ultrapurification is handled is divided into;

    the A. one-level is handled the processing that is visible material, adopt chemical filamentary material (as polypropylene fibre) to make filtering element, be placed in filtration vessel, current are by container the time, filtering element adsorbs the visible in the water, make visible and water sepn;

    the B. second-stage treatment, promptly macromolecular material in the water and water are carried out isolating processing, employing has rigidity and elastic macromolecular material (for example ethene) and makes in the container that filtering element is positioned over filtered water, current are through out-of-date, macromole in the water after one-level is handled is filtered element absorption, makes macromole and water sepn in the water;

    C. tertiary treatment, promptly small molecule material in the water and water are carried out isolating processing, adopt activated carbon and macromolecular material to make in the container that filtering element is placed in filtered water in conjunction with the poromerics of making, current are through out-of-date, and the small molecules dirt is attracted on the filtering element;

    D. level Four is handled, and promptly the ultrapurification of water is handled, and adopts fiber-reactive raw material of wood-charcoal material to make filtering element, is placed in the container of filtered water, and when current passed through, trickleer pollutent was attracted on the filtering element, thereby reaches the effect of ultrapurification.
