Treatment of malting wastewater using suspended-growth and attached-growth sequencing batch reactors

摘要

Malting wastewater was treated using both suspended-growth and attached-growth sequencing batch reactors (SBR). Both types of reactor were capable of treating the malting wastewater successfully with the attached-growth SBRs achieving higher treatment efficiencies. At a hydraulic retention time (HRT) of 2.66 days, the attached-growth reactors achieved removal efficiency for BOD, COD and NH_3-N of 99.2, 95.3, and 86.8/100, respectively.
