Abstract

The utility model relates to a filling used for sewage treatment, particularly a self-deformation elastic three-dimensional filling. The filling is composed of a central ring and a plurality of fan-shaped net sheets which are circled around the central ring, and a plane shape is formed. The net sheets are fixedly connected with the central ring by a plurality of radial tendons and vessels, the radial tendons and vessels are orderly arranged from one side of the net sheets to the other side of the net sheet in the sequence from a thick diameter to a thin diameter, and the radial tendons and vessels are mutually connected through tendons and vessels with tangential diameters. The utility model has fast initial film formation, more biological films can be produced on the net sheets, and the utility model has better effect of the sewage treatment.

Description

From the distortion elastic solid filler

The utility model relates to the sewage disposal filler, and is particularly a kind of from being out of shape elastic solid filler.

The various bio-carriers that use in current domestic and international biological contact oxidation process is disposed of sewage are of a great variety, have fixed, movable type is also arranged, hard filler is arranged, also have soft and elastic filler, net sheet type spin elastic filler, but always come with some shortcomings, as the price height, inconvenience is installed in transportation, and hard filler easily stops up, the easy conglomeration of soft-filler, the easily dead film in elastic filler center, shortcomings such as the semi soft packing specific surface area is little, easily forms the dead film in dead-air space, and net sheet type spin elastic filler transportation back is yielding.

The purpose of this utility model is to design a kind of novel elastic solid filler of distortion certainly for the deficiency that overcomes the above filler, this new packing is to utilize originally the experience characteristics of recoverable deformation behind the gravity of plastics, make each position on its carrier, microbial film absorption uniformly, metabolism, growth, eliminate the dead-air space, form the three-dimensional microbial film.

The utility model is realized as follows: describedly be made up of central ring and some fan-shaped net sheets being surrounded on around the central ring from being out of shape elastic solid filler, be characterized in: described filler is plane, have centre hole on its central ring, the net sheet is to connect firmly mutually with central ring by some elongated resilient radial muscle arteries and veins, described some radial rib arteries and veins, its thickness is all inequality, their opposite sides from a side ground from coarse to fine series arrangement of net sheet to the net sheet, adjacent radial rib arteries and veins links each other by some arcual tangential muscle arteries and veins again, is extruded with many needle-like cutting silks on each root radial rib arteries and veins.

During concrete the use, by centre hole several described fillers are together in series, and hang on (as shown in Figure 2) in the sewage with keeping suitable spacing, microorganism in the sewage will be attached on the net sheet, microorganism absorbs oxygen and the hazardous and noxious substances in the water, make and self grow gradually, and on the net sheet, form microbial film, promptly so-called biofilm, As time goes on, microbial film will increase gradually, weight increases, and under action of gravity, a side that has thin radial rib arteries and veins on the net sheet is with sagging naturally, the net sheet will become three-dimensional arrangement by original two dimensional structure, and whole filler then becomes the spiral pulpous state.At this moment, had openr space between adjacent net pieces, meanwhile, the tangential muscle arteries and veins of the arc on the net sheet will be elongated under action of gravity, make the area of net sheet increase many.

The utility model has following advantage:

1, it is fast to be out of shape elastic solid filler initial stage biofilm certainly.

2, the clearing that is had between adjacent net pieces helps objectionable impurities, oxygen and nutrition and walks between the net sheet, makes microbial film metabolism evenly.

3, the increase of net sheet area will make the more microbial film of energy output on the net sheet, improve the benefit of disposing of sewage.

4, the needle-like cutting silk of being given prominence on the radial rib arteries and veins can cut the bubble in the sewage, increases the surface-area of bubble, increases oxygen in water content, has quickened biomembranous growth.

Below in conjunction with accompanying drawing the utility model is described further.

Fig. 1 is the utility model plane plan structure figure.

Fig. 2 is the utility model user mode front view.

Among the figure: 1 central ring, 2 centre holes, 3 net sheets, 4 radial rib arteries and veins, 5 tangential muscle arteries and veins, 6 cutting silks, 7 suppending holes.

As shown in Figure 1, the utility model is made up of central ring 1 and six fan-shaped net sheets 3 being surrounded on around the central ring 1, have centre hole 2 on the central ring 1, net sheet 3 is to connect firmly by five elongated resilient radial muscle arteries and veins 4 and central ring, the radial rib arteries and veins is the opposite side from a side series arrangement of net sheet to the net sheet from coarse to finely, adjacent radial rib arteries and veins 4 is to link each other by some arcual tangential muscle arteries and veins 5, is extruded with many needle-like cutting silks 6 on each root radial rib arteries and veins.

Claims

1, a kind of from being out of shape elastic solid filler, form by central ring and some fan-shaped net sheets being surrounded on around the central ring, it is characterized in that: described filler is plane, have centre hole on its central ring, the net sheet is to connect firmly mutually with central ring by some elongated resilient radial muscle arteries and veins, by a side series arrangement of the net sheet opposite side to the net sheet, cross some arcual tangential muscle arteries and veins and link each other by adjacent radial muscle Maitong from coarse to finely for the radial rib arteries and veins.

2, according to claim 1 from being out of shape elastic solid filler.It is characterized in that: be extruded with many needle-like cutting silks on the radial rib arteries and veins.
