CHLORINE DIOXIDE PRODUCING METHOD CAPABLE OF RECYCLING TREATED WATER GENERATED DURING THE PRODUCING PROCESS AND CHLORINE DIOXIDE PRODUCING APPARATUS USING THE SAME

摘要

The present invention relates to a chlorine dioxide production method and a production apparatus capable of using the treated water generated during the production of chlorine dioxide as recycled water. The purpose is to use it to produce the maximum amount of chlorine dioxide. To this end, the present invention provides a method for producing chlorine dioxide using sodium chlorite, sodium hypochlorite, hydrochloric acid or sulfuric acid, (a) supplying air to the first reactor 1 (S10), (b ) supplying sodium chlorite, sodium hypochlorite and hydrochloric acid or sulfuric acid to the first reactor 1 (S20), (c) supplying air to the lower part of the first reactor 1 (S30), (d) supplying air to the second reactor 11 to generate microbubbles (S40), (e) supplying air to the third reactor 21 to generate microbubbles (S50), (f) ) discharging the treated water from the third reactor 21 (S60).
