摘要： PURPOSE:To prevent clogging of cord-like carriers and the carrier units thereof by installing the carrier units consisting of plural arrays of the cord-like carriers which are hung in a vertical direction and in parallel to single or multiple stages into a reaction column. CONSTITUTION:The waste water poured from a waste water feed port 15 to a water pressure drop detecting pan 17 falls by gravity in a waste water feed pipe 20 and ascends by passing the spaces between the arrays of the cord-like carriers 12 hung in parallel in the vertical direction as shown in the figure a white arrow W after arriving at the bottom of the reaction column 10. The waste water 1 comes into contact with the bacteria held on the cord-like carriers 12 and is cleaned during the ascending. The cleaned and treated water 4 is passed through a water collecting pan 19 and a water sealing device 24 and a discharged to the outside of the reaction column 10. The carriers 12 formed to a cord shape and are hung in parallel in the vertical direction guide the waste water upward and since the cord-like carriers 12 are arranged along the flow of the waste water, the deposition of the suspensible floating solids and sludge on the surface thereof is extremely decreased and the clogging of the cord-like carriers 12 and the carrier units 11 thereof is prevented.
