Document Type and Number:
WIPO Patent Application WO/2021/000875
Kind Code:
A1
Abstract:
Disclosed is a multi-layer textile water collection structure granular medium filter device, comprising a tank body (1), the inner part of the tank body (1) is divided into a filter space and a backwash expansion space, the upper portion of the backwash expansion space is equipped with an upper textile water pipe (4), which is communicated with an ozone water mixing pipe (7); the ozone can enter the backwash expansion space from the upper textile water pipe (4) to mix and react with incoming water, and ozone tail gas is discharged from the top of the tank body (1); an activated carbon powder can be introduced through the upper textile water pipe (4) and intercepted on the surface of the filter space to form an activated carbon layer (10) to absorb dissolved organic substances in the water and catalyze the decomposition of ozone; at least three layers of textile water collection devices are arranged in the filter space filled with granular filter material, so that the filter space can be fully utilized. The multi-functional granular medium filter device fully utilizes the filter space, can be used in multiple functions, saves floor space and filter material usage, and is especially suitable for entertainment water treatment systems in a swimming pool, a water park, etc. Disclosed is also a method of applying the multi-layer textile water collection structure granular medium filter device.
