摘要： PURPOSE:To enhance the removal capacity of ammonia nitrogen in the treatment of raw water varied in load by passing raw water through a filter tower packed with a filter bed holding bacteria while alternately changing over the same to upward flow and downward flow at every 1-10 days. CONSTITUTION:Raw water is brought into contact with nitrifying bacteria held to a filter bed 2 while filtered by the filter bed 2 and ammonia nitrogen in raw water is oxidized to be removed. Raw water is passed through the filter bed 2 while alternately changed over to downward flow and upward flow at every 1-10 days. By alternately performing the downward flow passage and upward flow passage of water at this frequency, nitrifying bacteria oxidizing ammonia nitrogen can be allowed to live not only in the upper part of the filter bed 2 but also in the lower part thereof in much quantity and the quantity of nitrifying bacteria held by the whole of the filter bed becomes very much. By this method, the lowering of the removal capacity of ammonia nitrogen can be suppressed low with respect to load variation such that the concn. of ammonia nitrogen in raw water suddenly increased.

摘要： PURPOSE:To perform treatment from a stage of an acclimation period even when the moldy smell decompositing bacterial bonded to an activated carbon filter material are not yet acclimatized by packing a filter tower with columnar granular activated carbon having a specific diameter as a filter bed. CONSTITUTION:In a biological contact filter apparatus wherein bacteria are held to the filtered in a filter tower formed by packing the filter tower with a filter material 3 and raw water is passed through the filter bed. The filter tower is packed with columnar granular activated carbon having a diameter (d) of 2.0-4.0mm as a filter bed. Herein, the granular shape of activated carbon is not a rod shape low in strength but means a shape whose length L to the diameter (d) is about 0.5-2.0. The filter bed constituted of the filter material 3 is low in the trapping ratio of suspended matter and a moldy smell is adsorbed by the properties of the activated carbon itself of the filter material during about two months at the beginning of operation until moldy smell decomposing bacteria are acclimatized.
