Embodiment 1

[0050] This embodiment provides a modular filter water and air distribution device, such as figure 2 and 3 As shown, it includes the filter brick body 1 and the water and air distribution assembly 2. The filter brick body 1 is a cuboid structure with a length of 400mm, a width of 200mm, and a height of 200mm. The schematic diagram of the appearance of the filter brick body 1 is as follows figure 1 As shown, the shell of the filter brick body 1 is made of HDPE, and the inside is filled with concrete, so the overall strength is high, and it is durable and not easily damaged. Such as figure 2 As shown, the inside of the filter brick body 1 is provided with two cavities 11 symmetrically distributed about the center line of the filter brick body 1 in the length direction; A flow control gap 13 is opened to make the cavity 11 communicate with the outside; the bottom of the filter brick body 1 is provided with a water flow channel 14, and the water flow channel 14 runs through th...

Embodiment 2

[0060] This embodiment is basically the same as Embodiment 1, the difference is: as Figure 4 and 5 As shown, the inner wall of the cavity 11 is provided with a permanent magnet material layer 12, and the permanent magnet material layer 12 is a plurality of rubidium magnet sheets 121, and the middle part of the rubidium magnet sheet 121 is provided with a fixing hole 122, which is used to wear the rubidium magnet sheet 121 On the bolt 123 on the inner side wall of the cavity 11 and fix it with a nut 124, at the same time, use glue to reinforce between the rubidium magnet sheet 121 and the inner side wall of the cavity 11. The glue can be plastic sticky magnet glue YH-896. Using the rubidium magnet sheet 121 with strong magnetism to form a magnetic field in the area of ​​the cavity 11 can magnetize and disturb the fine water flow ejected from the backwash to form high-oxygen water, which can greatly improve the backwash efficiency.

Embodiment 3

[0067] This embodiment is basically the same as Embodiment 2, the difference is: as Figure 8 As shown, the bottom of the water distribution rod 28 is provided with an oxygen-enriched filter screen 213. Further, the oxygen-enriched filter screen 213 is woven by steel fibers and oxygen-enriched anion fibers according to a three-dimensional weaving method, wherein the steel fibers root The quantity ratio of the number and the number of oxygen-enriched anion fibers is 1:3, and the aperture diameter of the oxygen-enriched filter screen 213 is 1.2mm. The steel fiber provides skeleton support, and the oxygen-enriched negative ion fiber can carry out preliminary oxygen-enrichment treatment on the backwash water, which can not only intercept debris to prevent the water distribution hole 27 from clogging, but also increase the oxygen content of the backwash to improve the backwash efficiency. A small pore size is not conducive to the interception of debris, and a too small pore size is...

Abstract

The invention discloses a modular filter water and air distribution device and its system and application method. The device includes a filter brick body and a water and gas distribution assembly. There are two cavities inside the filter brick body. There is a flow control gap at the bottom facing the two cavities respectively, and a water flow channel is opened at the bottom of the filter brick body. The water air distribution component includes a head body and a rod body. area, and the water distribution area located on the lower layer, the rod body includes a water distribution rod extending to the water distribution area, and an air distribution rod extending through the partition plate to the air distribution area. The uniformity of the water distribution and air distribution of the present invention reaches more than 90%, and compared with the conventional water and air distribution device, the backwashing energy consumption is reduced by 30%-40%. Moreover, the water distribution and air distribution device and system can be modularized and assembled according to different water treatment requirements, which is easy to popularize and apply.

Description

technical field [0001] The invention relates to the field of water treatment equipment, in particular to a water and air distribution device for a modular filter, a system and an application method thereof. Background technique [0002] Filtration or biological filtration is the core process unit of water supply and sewage treatment, mainly including denitrification biological filter, aerated biological filter, ozone-activated carbon biological filter, ordinary fast filter, siphon filter, etc. Backwashing is the core link of the filtration or biological filtration process, and is the basis for ensuring the treatment efficiency and long-term stable operation of water treatment structures. The most important component in the backwashing process is the water and air distribution device and system. The development of water distribution cloth The water and air distribution device and system with uniform gas, energy saving and consumption reduction have always been a major demand ...
