CARRIER ROTATION TYPE BIOLOGICAL DEODORIZING DEVICE

Japanese Patent JP3025196

B2

PROBLEM TO BE SOLVED: To provide a malodorous gas treating device whose treating capacity is large and whose startup time is short by including and fixing microorganisms in carriers of a large void in which pore paths of microorganisms run in every direction and the carriers is made a cartridge.
SOLUTION: This device has a casing 1, a rotating shaft 2 and a carrier cartridge 3. In the casing 1, a malodorous gas supply port 11, a discharge port 12, a water supply port 13, and drain port 14 are opened, and a fitting/removing port 16 which can be freely closed with a cover plate 15 is provided. The rotating shaft 2 is of horizontal type and whose one end is within the casing 1. The carrier cartridge 3 is that in which plural carrier discs 31 made of high density polyethylene are inserted in a cylinder 32 at intervals S and ferrules 33, 34 are fitted to both the ends of the cylinder 32 to include and fix microorganisms on the carrier discs 31, and it is fitted to the rotating shaft 2 in the casing 1 through the fitting/removing port 16 so that it can be freely fitted and removed, and the lower end part of the carrier discs 31 is positioned below the water level L in the casing 1. The malodorous gas supply port 11 and a discharge port 12 are prevented from making a short circuit by a partition 35.
