Abstract
PURPOSE: To secure a safe treatment by installing the brine electrolyzer adjacent to the nitrification/denitrification treatment device and then supplying the hydrochloric acid and the caustic soda which are generated through the electrolyzer as the pH adjuster for the nitrification/denitrification.
CONSTITUTION: The brine having a fixed concentration which received an adjustment in the brine dissolving tank 7 is sent by pressure to the electrolytic cell 8 to carry out an electrolysis. In the cell 8 the anode 10 and the cathode 11 are provided with the diaphragm 9 put between them. Then the electric power is supplied from the DC current source 12, and thus the brine is decomposed to discharge both Cl2 and H2. And the NaOH is produced in the cell 8. Both Cl2 and H2 thus produced are sent to the hydrochloric acid reaction tube 13 to be changed into the hydrochloric acid, and then absorbed into the water via the ejector 14 to be sent to the hydrochloric acid storage tank 15. On the other hand, the NaOH aqueous solution is sent to the storage tank 2 to be stored. Both the hydrochloric acid and the caustic acid thus generated are supplied as the pH adjuster for the denitrification tank 6 and the nitrification tank 3 respectively.
