Research of Biochemical Processing on Wastewater of Halogen Products

Abstract

The wastewater of halogen products were treated with UASB-SBR method, and the influence of the UASB reactor operation days on the CODCr removal were experiment, decolorization removal and turbidity removal, aeration time, as well as water load. The results showed that: the halogen products wastewater was treated by UASB process; the CODCr removal of wastewater can reach 86.2 %. Then the wastewater were treated with SBR process, and the CODCr of wastewater fell below 100 mg/L, which can meet the second grade discharge standard of “Integrated Wastewater Discharge Standard”（GB8978-1996）.
