Problems solved by technology

In order to ensure the quality of the filtered water, the currently used sand filter often uses quartz sand with a particle size of less than 1mm as the filter material, resulting in: ① low porosity of the filter layer, large filtration resistance, and low filtration speed; ② small specific surface area of ​​the filter material , Low dirt-holding capacity, short backwashing cycle; ③The filter material has a large specificity, difficult backwashing, high energy...

Abstract

The present invention relates to a long cellosilk high-speed filter by using long staple as filter material mainly includes filter tube body, long cellosilk high-speed filtering component, embedded flange connecting device, coupled multiring perforated tube gas distributor, shaft symmetrical water distributor whose centre is used for intaking water and periphery is used for discharging water and grid gas-water separator, in which in the filter tube body the long cellosilk high-speed filtering component is placed, the lower portion of the long-cellosilk high-speed filtering component is equipped with gas distributor, the backflush air intake tube is directly communicated with gas distributor, and the bottom of the lower cylinder body is equipped with filter effluent and backflush water intake tube.

Description

1. Technical field [0001] The invention relates to a high-speed filter using long fibers as the filter material, and belongs to the technical field of filter treatment of water supply and various sewage (waste water). 2. Background technology [0002] Filtration is one of the most commonly used treatment processes for removing suspended solids (turbidity) and its adsorbed substances in various types of water treatment. In order to ensure the quality of the filtered water, the currently used sand filter often uses quartz sand with a particle size of less than 1mm as the filter material, resulting in: ① low porosity of the filter layer, large filtration resistance, and low filtration speed; ② small specific surface area of ​​the filter material , Low dirt-holding capacity, short backwashing cycle; ③The filter material has a large specificity, difficult backwashing, high energy consumption, and the filter material is easy to lose. [0003] Fiber ball filtration is difficult to...
