Description
また、逆洗条件は、従来例と実施例とも同じ条件とした。すなわち、通水速度１００ｍ／ｈの水と通気速度３００ｍ／ｈの空気同時逆洗を４分間実施後、通水速度１００ｍ／ｈの水のみによる逆洗を行った。 The backwashing conditions were the same for both the conventional example and the example. That is, after performing the air simultaneously backwash water and passing air speed 300 meters / h of water flow velocity 100 m / h 4 minutes for backwashing by water only water passage velocity 100 m / h.

【発明の効果】
以上説明したように、本発明によれば、長繊維ろ過材の上方に浮上性充填材を設けることによって、長繊維ろ過装置のろ過能力を高めることができる。従って、長繊維ろ過装置の大きさや逆洗設備及び逆洗条件を変えることなく、比較的簡単な部材の追加で固形物捕捉量を増大することができる。特に、既存の装置について、比較的簡単な改造のみで固形物捕捉量を増大することが可能となる。

【Effect of the invention】
As described above, according to the present invention, the filtration capacity of the long fiber filtration device can be enhanced by providing the buoyant filler above the long fiber filtration material. Therefore, the amount of solid matter trapped can be increased by adding a relatively simple member without changing the size of the long fiber filtration device, the backwashing equipment, and the backwashing conditions. In particular, it is possible to increase the amount of solid matter captured by a relatively simple modification of an existing device.
