Research on the influences of high salt water on CaCO3 dissociation

For the consideration of wastewater zero discharge, many coal-fired power plants reuse the reverse osmosis concentrated water and chemical drainage in the desulfurization system ,but studies of influence to the CaCO3 dissociation by highly concentrated saline wastewater are rare.This paper analyzes negative influences of all kinds of ions when seperately exist in absorption tower, discussed the negative effect mechanism of highly concentrated saline wastewater on the CaCO3 dissociation.This study provides the reference for engineer practice when predicting the CaCO3 dissociation with all kinds of ions in.
