description The present invention relates to making method of modified magnesium lignosulfonate dry powder by using acid polishing waste liquid of paper making industry, it is characterized in that calcium hydroxide (or other alkali with similar property), is added into the liquid waste of acid polishing in paper making industry, after reaction is complete, it is concentrated, dried, surface treatment to thedried powder to obtain modified magnesium lignosulfonate powder which can be used as additive of concrete and can effectively raise, antideliquence ability of the concrete.
