Paper Title:
Condition Optimization of Dissolved Air Flotation-Filter and Mechanism Research
  Abstract

DAFF’s treatment effect on Yellow River reservoir water under different reflux ratios is studied in this paper. Determination of indicators are turbidity、CODMn、NH4+-N、UV254、particle counter and unconventional indicators, such as biomass、TOC、olfactory threshold and smell of factors. The best reflux ratio is 14%; The average value of NH4+-N、CODMn 、UV254、and turbidity of carbon-sand filter’s outlet is 0.125、1.61mg/L、0.033cm-1 and 0.21NTU, accordingly, the average removal rates are 58.64 %、40.44 %、27.96 % and 90.26 %; The micro-organisms in filter material are mainly existed in the upper layer of activated carbon filter; The micro-organisms provide carbon-sand filter beneficial conditions for its biological degradation effect.
