汚泥（又は活性汚泥菌）
（３）（１）、 （２）の混合品
のいずれでも良い。The fungi to be used may be (1) an effective microorganism group adapted to the odor, (2) activated sludge (or activated sludge bacteria), and (3) a mixture of (1) and (2).
次に菌担持多孔体の曝気槽への設置方法は、曝気槽上部
（第１図）、曝気槽液面上部（第２図）への三方法があ
る。Next, there are three ways to install the bacteria-supporting porous material in the aeration tank: at the top of the aeration tank (Fig. 1) and above the liquid level of the aeration tank (Fig. 2).
第１図において、悪臭３はブロアー４を経て活性汚泥槽
１内へ送入され、曝気槽の上部に設置された菌担持多孔
体２を通過して排気５される。In FIG. 1, a bad odor 3 is introduced into an activated sludge tank 1 via a blower 4, passes through a bacteria-supporting porous body 2 installed in the upper part of the aeration tank, and is exhausted 5.
第２図において、悪臭３はブロアー４を経て活性汚泥槽
１内へ送入され、曝気槽液面上部６に設置された菌担持
多孔体２を通過して排気５される。In FIG. 2, a bad odor 3 is introduced into an activated sludge tank 1 via a blower 4, passes through a bacteria-carrying porous body 2 installed above the liquid level 6 of the aeration tank, and is exhausted 5.
菌担持多孔体を曝気槽上部へ設置した場合の菌及び水分
の補給については以下の三通りの方法がある。There are the following three methods for replenishing bacteria and water when the bacteria-supporting porous material is installed above the aeration tank.
（１）Ｑｉ気槽液面から多孔質担体の距離が短かい時は
、曝気槽上部からの飛沫同伴分で補給は必要がない。(1) When the distance of the porous carrier from the liquid level of the Qi tank is short, replenishment is not necessary because of the droplets entrained from the upper part of the aeration tank.
（２）曝気槽よりポンプ・アップにより連続式又は定期
的に活性汚泥菌をノズルを通して噴霧する。(2) Spray activated sludge bacteria continuously or periodically by pumping up from the aeration tank through a nozzle.
（３）別に用意した馴致菌水槽より馴致菌を連続式又は
定期的に噴霧する。(3) Spray adapted bacteria continuously or periodically from a separately prepared adapted bacteria aquarium.
（２）、 （３）の操作は、菌及び水分を補給する目的
と同時に、失活したまま多孔質担体に付着している菌の
洗浄の目的も兼ねる。The operations (2) and (3) serve the purpose of replenishing bacteria and water, as well as cleaning the bacteria that remain inactivated and adhere to the porous carrier.
但し、別に水洗ラインを設けて洗浄を行う事も出来る。However, it is also possible to install a separate washing line for washing.
一方、曝気槽液面上部に設置した場合は、菌及び水分の
補給をしなくても良いし、同時に浮遊している状態の担
体同志がこすれ合って失活した菌の洗浄（除去）も行な
われる。On the other hand, if the aeration tank is installed above the liquid level, there is no need to replenish bacteria and water, and at the same time, the bacteria that have been deactivated by the floating carriers rubbing against each other can be washed (removed). It will be done.
