する。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a contact material for biological treatment, particularly a fluid such as gas or liquid utilizing a biological layer of aerobic bacteria attached to the contact material. The present invention relates to a contact material for a microbial reaction for performing an oxidation reaction at a temperature.

54−133754号公報）が知られている。<Prior Art> Conventionally, as a contact material for water treatment, particularly as a contact material for sewage treatment, a belt-like body provided with a large number of ring-shaped or hook-shaped small thread-like bodies is made of a core string or a core made of metal such as aluminum. Wrapped around the body to form a string (Japanese Patent Publication No. 49-134965,
No. 54-133754) is known.

成させていた。However, these contact materials adhere to the contact material by immersing the contact material in sewage water at the time of its use and sending air to a diffuser cylinder for blowing air bubbles separately provided below the contact material. It supplied oxygen to aerobic bacteria and generated biofilms.

られている。In addition, as shown in Japanese Patent Application Laid-Open No. Sho 62-97695 as an aeration contact material used in recent years for sewage purification treatment, it is composed of a pipe having an upper end connected to an air introduction pipe and a lower end provided with a fumarole. 2. Description of the Related Art There is known a lower-end fumed aeration contact material in which a core is covered with a sheath having a plurality of fiber loops around the core.

汚泥返送などの装置を必要としていた。However, in these means, since the position of dissolved oxygen in the water bubbles in the air bubbles blown out of the diffuser cylinder is separated from the position of the contact material, an excessive amount of ventilation is required, and the concentration of dissolved oxygen is required. In a high concentration part, a large amount of sludge is generated around the contact material, and in a low concentration part, the sludge hardly grows. As a result, the sludge adhering to the contact material is partially separated, so that a large amount of sedimentation and sedimentation of the sludge occurs. Therefore, a large and complicated apparatus for returning the sludge is required as a water treatment apparatus.
