Method for preparing pellets from rice husk and apparatus for removing odor using rice husk pellet bio-media

Abstract

A method for preparing pellets from rice husk includes: grinding rice husk; adding ammonia water to a mixture of ethylene vinyl acetate and poly(vinylacetate) to prepare a mixed, liquid binder; mixing the mixed, binder with the ground rice husk to obtain a binder/rice husk mixture; extruding the binder/rice husk mixture through an extruder; and cooling the extruded mixture at room temperature.

1 - 5 . (canceled) 
     
     
         6 . An apparatus for removing odor using rice husk pellet bio-media, the apparatus comprising:
 a circulating spray water reservoir;   a spray water pump connected to the circulating spray water reservoir and serving to move circulating spray water;   an odor air blower for injecting an odor air;   a bed layer of rice husk pellets located upstream of an odor air supply region into which the odor air is injected by the odor air blower; and   a circulating spray water injection nozzle located above the bed layer of rice husk pellets.   
     
     
         7 . The apparatus of  claim 6 , wherein the rice husk pellets in the bed layer have a cylindrical shape having a diameter of 2 cm and a length of 10 cm.
