Paper Title:
Effect of Diatomite Additive on Biomass Respiratory Activity in Activated Sludge
  Abstract

Laboratory and pilot scale experiments indicated that the diatomite additive could improve the stability of activated sludge process and the efficiency of COD removal for coal gasification wastewater treatment. In this paper, the effect of diatomite additive on biomass respiratory activity was studied to investigate the enhancing mechanism. Experimental results showed that diatomite additive could enhance biomass activity obviously when the biomass activity was inhibited by the wastewater with total phenols concentration of 188.9 mg/L -501.2 mg/L. It could be concluded that the mechanism of diatomite enhancing biomass activity were its adsorption of phenols and concentration of DO.
