Title: Determination of Chlorine Dosage during Chlorination of Finished Water from Waterworks
Abstract: Chlorination has a crucial role in the control of the amount of harmful bacteria in finished water from waterworks,and a reasonable chlorine dosage is important to control the bacteria content and production cost.Because hypochlorous acid has strong oxidizing nature and reacts with reducing substances in water,the amount of chlorine consumption by reducing substances need to be determined to ensure some residual chlorine.General reducing substances directly reduce hypochlorous acid to chloride,and the reaction between ammonia nitrogen and hypochlorous acid is more special,which has a significant effect on chlorine dosage.In the determination of residual chlorine,the national standard method was improved using DPD spectrophotometry,and good results were achieved.
