果的な方法は確立されていない。When water treatment is performed by a biochemical method, the purification rate varies depending on the quantity and type of microorganisms involved in purification per unit volume (1 m 3 ). It has been reported that a huge number of different types of microorganisms breed and adhere to porous ceramic materials to coexist and co-prosper, and continue to breed for generations. ing. Against this background, it is necessary to establish a certain usage in order to apply a porous ceramic material that is excellent in the fixation and reproduction of microorganisms. First, it is necessary to equalize the dissolved oxygen in the wastewater to the enormous number of aerobic bacteria that propagate and adhere to the porous ceramic material and bring them into contact with the bacteria to maintain their lives. Therefore, at first, only porous ceramic materials were filled individually, but they became in contact with each other and the supply air (oxygen) could not be distributed as expected, and the porous ceramic materials were also anaerobicized. It became clear. After that, as a result of trying the operation of an actual wastewater treatment device (3 m 3 / hr) for the past 2 years, it became anaerobic in 2 days and turned black and generated hydrogen sulfide. At the same time, we tried to remodel the device, but we could not get good results, and finally we had an idea to keep the porous ceramic materials themselves with a space between them, and we had to devise the necessity and direction. The reason for this is that a huge number of different types of microorganisms propagate and adhere to the porous ceramics material, and it is necessary to contact the dissolved oxygen in the container with the bacterial cells. It has been found that the wastewater passage is hindered when it is in contact with the steel plate, and that the oxygen is insufficient from the contact point of the porous ceramic material to cause decomposition. It has been found that it is important to overcome this factor of decay and maintain the space between the porous ceramic materials to be effective and maximum. In recent years, research on wastewater treatment technology using porous ceramic materials has been actively conducted, but an effective method has not been established yet.

題がある。However, according to a conventional wastewater treatment apparatus having a microorganism-fixed bed, a panel (Japanese Patent Publication No. 57-4387) or weir (Japanese Patent Laid-Open No. 61-230787) holds the microorganism-fixed bed and arranges it in the wastewater. Therefore, there are the following problems.
(1)微生物固着床に汚泥が蓄積することにより浄化作用
の低下や微生物固着床の損傷を生じやすい。(1) Accumulation of sludge in the microorganism-fixed bed tends to reduce the purification action and damage the microorganism-fixed bed.

To do.

であったことから、球状のときの３％は非常に低い達成
率である。Prior to the present invention, a spherical holder was designed, but it was found that various drawbacks occur when it is filled in a wastewater treatment catalytic oxidation tank. To explain this drawback, the designed spherical contact material holder has a diameter of 20 cm and a diameter of 2 c inside.
A total of 7 rod-shaped porous ceramic materials with a length of 12 m and a length of 12 cm are placed at appropriate intervals. If a spherical tank is filled in a 1 m 3 water tank, theoretically 125 pieces can be filled in total. But in reality it's a random filling, a total of 10
Seven was the average number. Moreover, the volume of one porous ceramic material is 4 × 10 -5 m 3 , and the total volume within 1 m 3 is 4 × 10 -5 × 107 (pieces) × 7 (pieces) ≈ 0.03 m 3 . The filling rate of porous ceramic material is 3%, which is very low. Since this is spherical, a space is created between adjacent spheres and becomes a dead space,
The filling of a porous ceramic material having a length within a sphere will be constrained in terms of placement. Theoretical filling amount 12
When 5 pieces / m 3 is reduced to 107 pieces / m 3, there is a loss of 14.4%,
This means that an error of 14.4% is likely to occur as a factor during basic design. On the other hand, from the data obtained from the verified values, the average filling rate of the porous ceramic material is 7.6%.
Therefore, 3% for the spherical shape is a very low achievement rate.
尚、一般的な接触材の選定規範として次の事項がある
が、これも充填率を下げている要因の１つとなってい
る。Incidentally, there are the following items as a general selection rule of the contact material, but this is also one of the factors that lower the filling rate.
(1)接触槽接触材充填部に対して、接触材充填率は15％
以下（空隙率は85％以上）でなければならない。(1) Contact tank filling rate is 15% with respect to contact tank filling section
It must be below (porosity 85% or more).
(2)汚水による目詰りを防ぎ、廃水の通過性を良好にす
るために、接触材素材相互間が３cm以上隔っているこ
と。(2) In order to prevent clogging due to sewage and to improve the passage of wastewater, the distance between contact materials should be 3 cm or more.
しかし、これらの条件があるとしても、デッドスペース
による14.4％の充填量の減少、算定基準の誤差発生要
因、３％低い充填率等があると、装置を満足に設計する
ことができない不都合が生じる。However, even with these conditions, if there is a 14.4% reduction in the amount of filling due to dead space, a factor that causes an error in the calculation standard, and a 3% lower filling rate, the device cannot be designed satisfactorily. .

And the adherence of microorganisms to the surface of the porous ceramic material is improved. This also causes the dissolved oxygen in the wastewater to effectively contact the surface of the ceramic material. At this time, by causing the bubbles generated from the air supply device to flow upward in order from the lower stage,
The bubbles always contact the upper porous ceramic material, are dispersed, and diffuse to promote aerobicization.

On the other hand, when using a porous ceramic material as the contact material, there is data indicating that the BOD volume load per m 3 increases about 8 to 15 times, and it is possible to effectively use the advantages of the space support and the frame. The shape of the contact material of the present invention has an advantage in practical use.
