AbstractIn the equivalent self-neutralizing process of regenerating effluent, the effluent in cationic bed is one-step regenerated with sulfuric acid as regenerating agent or stepped or one-step regenerated with hydrochloric acid as regenerating agent with the regenerated effluent being exhausted into neutralizing pool; the effluent in anionic bed is regenerated with sulfuric acid as regenerating agent with the regenerated effluent being also exhausted into neutralizing pool; and the regenerated effluent from the cationic bed and that from the anionic bed are mixed in the neutralizing pool before exhaust. Through full mixing of the regenerated effluent, exhaust in the relevant standard may be reached. The present invention can reduce water producing cost.
