Abstract

A multi-medium filter comprises a tank body, a water inlet pipe formed at the top end of the tank body, an exhaust pipe formed at one side of the water inlet pipe, and a water drainage outlet formed at the bottom end of the tank body; a filtration screen board is arranged close to the bottom end in the tank body; water drainage caps are arranged on the filtration screen board, a plurality of support tubes are arranged at the bottom end of the filtration screen board, bottom ends of the support tubes are connected with the tank body, a plurality of layers of mutually stacked filtering material screen racks are arranged above the filtration screen board, the filtering material screen racks comprise disc-shaped brackets and grille-shaped supports perpendicular to the disc-shaped brackets, the grille-shaped supports comprise a plurality of staggered plate bodies, top ends of the plat bodies are zigzag, each space separated by the grille-shaped supports of the filtering material screen racks are filled with a filtering material, and the filtering material includes quartz sand, activated carbon or anthracite.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to the improvement of filters. Background technique [0002] The multi-media filter is a process of using one or several filter media to pass the water with high turbidity through a certain thickness of granular or non-granular materials under a certain pressure, so as to effectively remove suspended impurities and clarify the water. However, during the filtering process of the existing filter, the interior of the filter material cannot be effectively washed during backwashing, and the number of layers of the filter material is single, so that various combinations cannot be performed, and the filtering effect is effectively improved. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides the following technical solutions: a multi-media filter, including a tank body, a water inlet pipe on the top of the tank body, an e...
