For contact oxidation tanks used for water purification, the tank is simply filled with filler, or a zigzag water passage formed in the tank by a partition plate is filled with filler to supply oxygen. However, there have been conventionally provided structures in which water is purified by passing raw water between the fillers. However, since conventional products supply oxygen only with oxygen supply devices such as aerators and ejectors, it is necessary to install a large-scale oxygen supply device inside the tank, and moreover, it requires a large amount of power. The disadvantage was that it required

い。 As shown in Figs. 1 and 2, the contact oxidation tank of the present invention has a filler 2 with a small specific surface area (hereinafter simply referred to as filler 2) in the tank 1, and a filler 2 with a large specific surface area on the top for adhesion of algae. It is filled with filler material 3.
Raw water is passed through these spaces for water purification treatment. Inside the tank 1, a zigzag water passage 8 having a bent detour 7 on the raw water inlet 5 side and the treated water outlet 6 side is formed by four partition plates 4. 8 is filled with the above-mentioned fillers 2 and 3, and the raw water flowing into the tank 1 from the raw water inlet 5 passes through the fillers 2 and 3 and moves in a zigzag pattern along the water passage 8, during which time the raw water flows into the tank 1 through the raw water inlet 5. This example shows a system that purifies water. However, it is not limited to this. Although not shown, a tank is formed in a relatively elongated shape,
It may be a so-called straight type contact oxidation tank filled with a filler inside. In addition, the filler 2 is made of synthetic resin and has an uneven surface, and is shown as being stacked at a predetermined interval and parallel to the flow direction of the raw water. The filler may have the shape of . This filling material 2
An oxygen supply device 9 is installed in the lower part of the tank. The oxygen supply device 9 is for supplying dissolved oxygen into the raw water, and is exemplified by a diffuser pipe to which a blower 10 is connected. If this oxygen supply device 9 is installed in the lower part of the filler 2, dissolved oxygen can be reliably supplied to the inside of the filler 2 from the lower part. As shown in FIG.
A filler 3 for algae adhesion is provided which has a larger specific surface area than the above. Specific surface area is the ratio of volume to surface area (m 2 /
m 3 ), and to make it larger than filler 2,
As shown in the figure, this is also possible, for example, by narrowing the interval. This algae adhesion filler 3
is installed so that its upper part is exposed above the raw water surface and its lower part is submerged in the raw water. As the filler material 3 for algae adhesion, one having a wavy parallel plate structure is illustrated, but other fillers for algae adhesion such as a net-like structure, a string-like structure, a pine-like structure, etc. may be used. This algae adhesion filler 3 is for supplying oxygen produced by the photosynthetic action of the algae that has grown on it into the raw water, and it can be submerged up to 30 cm into the raw water and exposed up to 10 cm from the surface of the raw water. This is preferable because it prevents light from being blocked by the filler material 3 for algae adhesion and also prevents raw water from passing over the upper surface of the filler material 3 for algae adhesion. Also,
It is preferable that the filler material 3 for algae adhesion is removably provided on the upper surface of the filler material 2 because cleaning becomes easier.
なお、符号１１は通水路８に横架した架台を示
し、該架台１１に充填材２を載置してある。 Note that the reference numeral 11 indicates a pedestal placed horizontally on the water passage 8, and the filler 2 is placed on the pedestal 11.

The contact oxidation tank described above is made of synthetic resin such as fiber-reinforced polyester or vinyl chloride, and
For example, it is used to purify raw water for water supply by a method called catalytic oxidation method.
To purify raw water, the raw water flows into the tank 1 from the raw water inlet 5. Then, the raw water is passed through the water channel 8.
The water flows in a zigzag pattern along the passageway 8 between the filler 2 and the lower part of the algae adhesion filler 3. At this time, oxygen is produced by the photosynthetic action of the algae that have grown on the algae adhesion filler 3.

On the other hand, oxygen is reliably supplied between the fillers 2 from below by the oxygen supply device 9, and catalytic oxidation of the raw water and the microbial membrane is performed.
The treated water then moves from the treated water outlet 6 to a settling tank (not shown).

As described above, according to the contact oxidation tank of the present invention, when performing aerobic biological treatment of raw water, not only oxygen is reliably supplied from the oxygen supply device, but also a part of the necessary oxygen is absorbed by the photosynthetic action of algae. Since the water is supplied using the oxygen supply system, a small-scale oxygen supply device is sufficient and its power can be reduced, and furthermore, catalytic oxidation between the raw water and the microbial membrane is carried out well.
