| 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 in this article.Through analysis and comparison,it is concluded that using FeSO_4 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. |
