Treatment of the Liquor Wastewater Using Sequencing Batch Reactor

Abstract:

Sequencing Batch Reactor (SBR) was investigated for the treatment of liquor wastewater in this paper. This study includes the test of start-up of the SBR, running of the reactor by treating the wastewater. During the start-up process the activated sludge was cultured and acclimated. After acclimation the removal efficiency of COD_cr can reach around 99%. Following investigations were focused on evaluation of the treatment efficiency and the reactive cycle during running the SBR. The experimental results showed that running parameters of SBR reaction system were Fill 0.5 h, React 10.0 h, Settle 2.0~2.5 h, Drain 0.5h, Idle 4.0h. Under these conditions the removal rate of COD_cr can reach 99%. So the performance of SBR for the wastewater was satisfactory as the wastewater had 1400~2000mg/l of COD_cr. The cyclic operation of SBR used in this study proved more effective in treating the wastewater.
