Abstract

Abstract: The factors influencing on consumption of acid and alkali for ion exchange resin regeneration were analyzed. The reasons of high acid and alkali consumption in Fularji General Power Plant and relevant countermeasures were expounded in detail. In order to prevent and decrease the pollution of ion exchange resin, a new resin cleaning method was proposed which integrates the traditional chemical medicament cleaning and ultrasonic cleaning technology. The working exchanging capacity of ion exchange resin was raised and the consumption of acid and alkali was reduced by using the new cleaning method.

Key words: resin, consumption of acid and alkali, pollution, regeneration process, regeneration mode, ultrasonic cleaning
