[0054] will now refer to figure 1 and figure 2 A first embodiment of the present invention is described. The non-aerated water treatment plant 1A in the first embodiment includes an anaerobic reactor 3 placed in the preceding stage and an aerobic reactor 10 placed in the subsequent stage. The drain port of the pump 2 is connected to the bottom of the anaerobic reactor 3 via a line L1, and by the driving of the pump, sewage is introduced upward into the anaerobic reactor 3 from a sewage supply source (not shown).
[0055] In the carrier filling section 4 of the anaerobic reactor 3, a plurality of rope-shaped carriers 6 are suspended from and supported by the supporting means 5. The rope-shaped carriers 6 are arranged so that the intervals between them are almost equal. The rope-shaped carrier 6 comprises a plurality of ring-shaped fluff or brush-like fluff (synthetic fibers, such as nylon) implanted around the column string, and adheres to the surface of the carrier with an...

[0092] The non-aerated water treatment plant 1B according to the second embodiment will be referred to Figure 5 to describe.
[0093] In the apparatus 1A of the first embodiment, the rope-shaped carrier 15 is supported by the supporting means 14, while in the apparatus 1B of the present embodiment, the rope-shaped carrier 15 is directly supported by the water storage part 21 without a dedicated supporting means . That is, in the apparatus 1B of the present embodiment, a horizontal pin is connected to the upper end of the rope-shaped carrier 15, and this horizontal pin extends above the opening 22 of the reservoir portion 21 to suspend and support the rope-shaped carrier 15.
[0094] In this embodiment, unlike the first embodiment, there is no significant gap between the connecting water guide 23 and the supporting device 14, but there is a considerable gap near the rope portion of the rope-shaped carrier 15 ( gap between the opening 22 and the horizontal pin).

[0099] According to the non-aerated water treatment equipment 1C of the third embodiment of the present invention, see Figure 6 to describe.
[0100] In the apparatus 1C of the present embodiment similar to the apparatus 1B in the second embodiment, water is supplied directly from the water reservoir portion 21 to the carrier 15 in the carrier filling portion without connecting water guide members. However, the device 1C in this embodiment is provided with only one opening 22 . That is, the bottom of the reservoir part 21 is provided with a single opening 22 at the center, and by hanging the stopper 15b on the wall surrounding the opening 22, a plurality of string-shaped carriers 15 can be hung on the reservoir part 21 and supported by it. A plurality of rope-shaped carriers 15 whose upper ends are connected to the stopper 15b extend radially so as to have a certain interval therebetween.
[0101] In the apparatus of this embodiment, processing efficiency can be improved b...
