繊維集積体の現出が望まれている。In conventional fiber aggregates, when used continuously or for a long period of time, microorganisms generated adhere and accumulate between the fiber aggregates, resulting in clogging or foul odors. Therefore, with conventional filtration methods, it is difficult to maintain sufficient water quality. Therefore, it is desired to develop a fiber aggregate that can further reduce clogging and bad odor even when used in this manner.

である。The fiber aggregate is an aggregate of various fibers. As this fiber aggregate, for example, felt, nonwoven fabric, or an aggregate in which fibers are partially bonded with rubber, resin, or the like is used. This felt may be needle punch felt, compressed felt, woven felt, or the like. The fibers used in this fiber assembly may be organic fibers, inorganic fibers, or a mixture thereof, but organic fibers are preferred. This is because photosynthetic bacteria have better adhesion. Among organic fibers, synthetic fibers such as nylon, polyester, polyacrylonitrile, polyethylene, polypropylene, polyamide, wholly aromatic polyamide, etc. are preferable to natural fibers. Synthetic fibers are
This is because it has excellent mechanical strength, water resistance, seawater resistance, weather resistance, etc.

Therefore, the digestion efficiency of photosynthetic bacteria and other malodorous components is good, and the decomposition of organic components in wastewater is also good, so there is less clogging and bad odors, and it is also excellent in purifying wastewater, especially for high-concentration organic wastewater treatment. or continuous,
Very useful as a filter for long-term use.

脱離がしにくく寿命が長い。Further, in the present invention, since the above-mentioned fiber aggregate is used, photosynthetic bacteria can be easily and firmly fixed on the fibers and between the fibers. In particular, when fiber aggregates are used only for photosynthetic bacteria that do not have the ability to form spores, their attachment is effective. Therefore, in the present invention, since photosynthetic bacteria are effectively immobilized, they are difficult to detach and have a long lifespan.

A substantially square fiber aggregate of 0x200x3 (thickness) mm is prepared. This fiber assembly is made of needle felt, and is made of a mixture of synthetic fibers such as nylon 6/6 and polyester. The thickness of the fiber is approximately 3~
It is lOμm.

赤色に色づいて見える。Next, as shown in FIG. 1 after immobilization, a liquid aqueous dispersion of photosynthetic bacteria (purple non-sulfur bacteria) 3 (water Approximately 6 g of this bacteria (approximately 1 mj) per approximately 1 kg was applied to the fiber aggregate 2 using a brush so as to be as uniform as possible.
The photosynthetic bacteria 3 were immobilized by allowing the plate to stand for 5 days. The results are shown in FIGS. 1 and 2. Figure 1 is a trace of a part of the photograph at almost the same size, and Figure 2 is a trace of a micrograph (50x magnification) of the fiber aggregate portion with immobilized photosynthetic bacteria 3 shown in Figure 1. This is what I did. This photosynthetic bacterium 3 is shown by the hatched area in FIG. 1, and it is shown that it is attached and growing on and between the fibers 21. Since the color of these cells cannot be seen under a microscope, the epiphytic state of photosynthetic bacteria is not illustrated in FIG. However, since the bacterial cells contain large amounts of bacteriochlorophyll and carotenoids (photosynthetic pigments), the entire surface of the aggregate appears red, as shown in Figure 1.

内に循環される。First, the filtration section 8 was placed on the top of the water tank 4 having a size of approximately 1 (width) x 5 (length) x 1 (height) m. The above-mentioned photosynthetic bacteria-immobilized fiber aggregate 1 is placed in the outer frame 11 in the filter section 8.
It is supported and placed as a filter and fixed. By the operation of the pump 7, the water in the water tank 4 is applied to the surface of the fiber aggregate l from the nozzle 10 connected to the discharge pipe 9 through the water suction part 5 arranged in the water tank 4 and the water suction pipe 6 connected thereto. Water is discharged. Note that the discharge amount of the pump 7 is approximately 617 minutes. The water that has been filtered through this fiber aggregate is then collected in a water tank 4.
circulated within.
この水槽4内に、水約1トン及び大きさ約300mmの
アメリカンロブスタ−8匹を入れて、飼育した。Approximately 1 ton of water and 8 American lobsters each having a size of approximately 300 mm were placed in this aquarium 4 and raised.

It shows that it is not. In addition, this filtration surface is
At the same time, it shows a red color, and at the same time shows a black or brown color indicating filtrate such as leftover bait.
一方、比較のために光合成細菌が固定化されていない同
形状の繊維集積体を同様の飼育水槽において飼育した。On the other hand, for comparison, fiber aggregates of the same shape without immobilized photosynthetic bacteria were reared in a similar rearing tank.
この両者を比較すると、約2日を経過すると比較例では

Furthermore, the water in the water tank was also cloudy in the comparative example compared to the example. Furthermore, after being kept for about 3 consecutive days, the Comparative Example started to emit a bad odor compared to the Example, but the Example did not emit any bad odor.

ずに飼育することができたのである。Furthermore, in this example, when the filter was used continuously for 120 days without replacing it, it was possible to raise the fish without replacing the seawater. With conventional filtration methods, the decomposition of excluded substances (feces, etc.) and leftover food is not sufficient, so if the filter becomes clogged within 2 to 3 days as described above, depending on the number of individuals housed, the water becomes cloudy and the odor becomes bad. emanate. Therefore, it becomes necessary to replace the filter frequently, and even if the filter is replaced frequently, the water quality is not sufficiently maintained, so the seawater needs to be replaced. However, in this embodiment, harmful ammonia and hydrogen sulfide generated from excluded substances are taken in to reduce the nitrogen content in the water, thereby increasing metabolic function and promoting water purification. Therefore, it was possible to raise them as they were for a long period of 120 days without changing the seawater.
以上において、本実施例の光合成細菌固定化繊維集積体
を微生物フィルターとして用いると、悪臭がなく又排水
処理も有効且つ確実に行われ、フィルターの目詰まりも
起きなく海水を取り替える必要もない。In the above, when the photosynthetic bacteria-immobilized fiber aggregate of this example is used as a microbial filter, there is no bad odor, wastewater treatment is performed effectively and reliably, the filter is not clogged, and there is no need to replace the seawater.

The filtration device used can also be in various forms. For example, the shape and size of the water tank, the amount of water used, the presence or absence of fresh water or seawater, the capacity of the pump, etc. are variously set depending on the purpose and use. The filtration part may also be fixed to one end of the water tank, or the water to be used is drawn out from one lower end of the tank and transported to the filtration part by a pump. You can also do that. Further, a plurality of filters may be stacked, a support body may be arranged at least at the lower end of the filter, and various methods of arranging and fixing the filters can be used. .
