Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a contact material having a three-dimensional structure for use in water purification treatment, which can be formed into a three-dimensional structure having a water passage by assembling from a substantially plate or sheet. Regarding the contact material.

[0002]

2. Description of the Related Art Many types of contact materials for water treatment have been proposed.
As a device that can purify water by adsorption or bonding, a three-dimensional structure having a fibrous or continuous foam partition, a skeleton having a cross-sectional net or grid shape, and a water passage formed inside is used. I have.

[0003]

Since the above-mentioned conventional one is extruded in a mesh or lattice shape, it is produced as a three-dimensional structure having a number of relatively large continuous holes serving as water passages. It remains in a state. Therefore, storage space and distribution costs in factories are greatly reflected in product prices. In addition, since a large storage space is required for preliminary storage at a wastewater treatment plant or at a use point at the end, the need for eliminating such waste has been pointed out as it is reflected in facility construction costs.

[0004]

Accordingly, as a result of studying the above-mentioned problems, a contact material capable of purifying water by filtering, adsorbing, or binding suspended or immobilized substances of microorganisms in water. A first water-permeable member having a fitting groove, a second water-permeable member having a fitting groove at one end, and a third water-permeable member having a fitting groove at an end opposite to the second water-permeable member. A plurality of second water-permeable members are assembled in an intersecting state with respect to one fitting groove of the plurality of first water-permeable members, and a plurality of second water-permeable members are assembled with respect to the other fitting groove of the plurality of first water-permeable members. The third water-permeable member was assembled in an intersecting state to obtain a contact material for water treatment having a three-dimensional structure.

The first water-permeable member having a fitting groove and the second water-permeable member are provided, and a plurality of second water-permeable members are provided for one or both of the plurality of first water-permeable members. Were assembled in a crossed state to obtain a contact material for water treatment having a three-dimensional structure.

The first to third water-permeable members are substantially plate-shaped or sheet-shaped. These are most easily used with a flat surface, but the present invention can also provide a wavy shape, a curved shape to increase the contact area for purification, and a through-hole in a plate-shaped or sheet-shaped part. Of the present invention. These materials are also used as members usually used as contact members, for example, a synthetic resin plate or a foamed plate, a plate-like body or a nonwoven fabric having a porous structure obtained by integrating and integrating various natural fibers or synthetic fibers, or a flexible material. Even if it is soft as a single piece such as a multi-layered fabric or a thick multi-layered fabric, the form stability can be obtained by assembling it as shown in the figures described later.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 FIGS. 1 to 3 show a first embodiment of the present invention, in which one end portion is placed on top of a porous plate-shaped first water-permeable member 1 having four fitting grooves 1a and 1b at both ends. The second water-permeable member 2 having four fitting grooves 2a at the (lower) portion, and the third water-permeable member 3 having the fitting groove 3a at the end (upper) opposite to the second water-permeable member 2. It is configured. As shown in FIG. 1, the fitting grooves 2a of the four second water-permeable members 2 are fitted in one of the fitting grooves 1a of the four first water-permeable members 1 in an intersecting state, and the two are formed at right angles. It is assembled together. Further, the four third water-permeable members 3 are assembled to the other fitting grooves 1a of the four first water-permeable members 1 by the fitting grooves 3a in an intersecting manner from below. The length of the first water-permeable member 1 is twice the length of the second water-permeable member 2 and the third water-permeable member 3, that is, the length of the second water-permeable member 2 and the third water-permeable member 3 is the first. Since it is half the length of the water-permeable member 1, the contact member 5 for water treatment has a lattice-like shape as shown in FIG. 3 and has a three-dimensional cuboid structure having a plurality of water passages 4 therein. In this example, four fitting grooves 1a and 1b are provided at the top and bottom of the first water-permeable member 1, however, by providing two or more appropriate fitting grooves 1a and 1b, It can be a contact material for water treatment having a structure. Further, as shown in FIG. 2, a contact material 5 for water treatment having a rectangular solid structure is provided.
May be used in a plural number.

Embodiment 2 FIG. 4 shows a second embodiment of the present invention, in which two of four fitting grooves 1a of one fitting groove 1a of four first water-permeable members 1 are provided. Thus, two half of the fitting grooves of the fitting grooves 2a of the four second water-permeable members 2 are assembled in an intersecting state. Further, in this example, the third water-permeable member 3 is similarly assembled in a crossed state from below, and the whole is organically spread horizontally. If an unconnected portion remains at the end, it is preferable to use a half-width and half-fitting groove.

Embodiment 3 An example shown in FIG. 5 comprises a first water-permeable member 1 and a second water-permeable member 2 having fitting grooves at both ends, and a plurality of first water-permeable members 1.
The fitting grooves 2b of the four second water-permeable members 2 are assembled in an intersecting state with one of the fitting grooves 1a to form a three-dimensional structure. The first water-permeable member 1 and the second water-permeable member 2 have the same length,
The contact member for water treatment can be used as it is, or the third water-permeable member 3 of the above embodiment may be used for the upper or lower part. Also, the fitting groove 1a of the first water-permeable member 1 and the fitting groove 2b of the second water-permeable member 2 are provided to be approximately half the length of the first water-permeable member 1 and the second water-permeable member 2, and assembled. You may do so.

Embodiment 4 Although the above embodiments have been substantially rectangular in plan view (see FIG. 2), as shown in FIG.
And the intersection angle of the second water-permeable member 2 (and the third water-permeable member) is 90
The shape may be a rhombus or a parallelogram with a wider or narrower angle than °.

The various structures of these embodiments are appropriately designed and used depending on the accommodation space of the contact material for water treatment of the water purification device. An example is shown in FIG. In this example, a flat first water-permeable member 1, a second water-permeable member 2, and a third water-permeable member 3 are three-dimensionally assembled in a second anaerobic filter bed 7 of a small-sized combined treatment septic tank 6 for home use. A plurality of the structures shown in FIG. 3 are arranged vertically and horizontally. The upstream is an anaerobic filter bed first chamber 8, and the downstream is a contact aeration tank 9. The sewage entering the anaerobic filter bed second chamber 7 is decomposed by microorganisms in the water fixed by passing through the water treatment contact material 5 of the present invention, and is purified by filtering, adsorbing or binding of suspended substances. Perform

[0012]

According to the present invention, the process of storing and distributing the contact material for water treatment in a factory and the need for a large storage place in a wastewater treatment plant or a terminal use place are eliminated. As a result, it is possible to reduce distribution costs and to eliminate various wastes and difficulties caused by a large volume other than the conventional case when not in use.
