Abstract

PURPOSE: A water-containing cellulosic substance and ozone are subjected to gas- solid contact and the remaining ozone is passed through aqueous ammonia, then the resultant cellulosic substance is dipped in the aqueous solution, thus increasing the biodegradability of the titled substance.
CONSTITUTION: After a cellulosic substance such as straw, bagasse or used paper is treated with water in the mixing tank 1 to increase the water content, it is subjected to gas-solid contact with the ozone fed from the ozone generator 3 in the ozone- treating tank 2 and sent to the ammonia-treating tank 4 where it is dipped in an aqueous ammonia solution under stirring. At this time, the exhaust gas from the ozone-treating tank 2 is passed through the ammonia-treating tank 4. The cellulosic substance treated with ammonia in the tank 2 is pressed with the press 5 and heated with the heater 6 to remove ammonia.
