れ換えた場合より浄化処理能力の回復が速くなる。(Function) In the present invention, when organic wastewater is purified for a long period of time, the purification capacity of the porous granules themselves, which are mainly composed of calcium silicate, decreases, and the purification capacity of the entire septic tank decreases. When the amount of porous granules has decreased, a part of the porous granules that had been filled in the septic tank, for example half, is left intact and replaced with new porous granules. Then, the biofilm on the surface of the remaining porous granules remains in the septic tank, so when the purification treatment operation is restarted and the organic wastewater is supplied to the septic tank, the microorganisms present in the organic wastewater are removed. However, due to the action of the biofilm remaining in the septic tank, it becomes accustomed to the purification treatment environment and has purification ability. Therefore, the recovery of purification capacity is faster than when the entire inside of the septic tank is replaced with new porous granules.

流通路７内へ流入する。The organic wastewater A discharged from the discharge port 1 of the settling tank flows down into the flow path 7 directly below it, and is passed through the gap g at the lower end of the partition plate 8.
It flows into the first purification chamber 3 from below. A plurality of cylindrical containers 12 made of a mesh are disposed in the first purification chamber 3, and each cylindrical container 12 is filled with porous granules 13 on which a biological layer is previously formed. Therefore, in the process of flowing upward in the first purification chamber 3, the organic wastewater A enters the cylindrical container 12 and comes into contact with the biological layer. Then, the batter contained in the organic wastewater A is captured by the biological layer. In addition, calcium ions in calcium silicate hydrate have a dephosphorizing effect. The organic wastewater A treated as described above overflows from the upper edge of the partition plate 9 at the front of the first purification chamber 3 and flows into the flow path 7 between the first purification chamber 3 and the second purification chamber 4. Inflow.
前記流通路７内に流入した有機性排水Ａは、前記と同様

１２を抜き出した場所には、その抜き出した筒状容器１
２と同一形状の空間が残る。By the way, when a purification device that operates as described above is used for a long period of time, the calcium silicate that makes up the porous granules 13 gradually dissolves and becomes smaller, and organic substances etc. adhere to the surface. This will reduce the purification capacity. In such a case, the operation of the purification treatment device is temporarily stopped and the desired purification chambers 3 to 3 are removed as shown in FIG.
6, the other cylindrical containers 12 are pulled out upward by grasping their upper end frames 12a while leaving a part of the plurality of cylindrical containers 12. Then, the porous granules 13 as well as the cylindrical containers 12 are extracted from the purification chambers 3 to 6. At this time, the cylindrical containers 12 are simply arranged in the purification chambers 3 to 6 so as to be adjacent to each other in an upright state. Since there is only one, it can be easily extracted. In addition, in the place where the cylindrical container 12 was extracted as described above, the cylindrical container 1 that was extracted is
A space with the same shape as 2 remains.
そして、この新しい多孔質粒状体１３を充填した筒状容
