| Abstract: | As it existed weakness in chromic wastewater treatment technology in color kinescope industry,solutions to improve them from aspects of reducing agent and coagulating reagent are proposed m this article. Through analysis and comparison,it is concluded that using FeSO4 as reducing agent could broaden pH adjusting range of oxidation-reduction reaction and improve safety of operation; using the new high-efficiency coagulating reagent and adopting sludge recirculation technology could significantly reduce chemical usage and content of COD and SS in treated wastewater . |
