A novel approach to estimate and control denitrification performance in activated sludge systems with respirogram technology
文献摘要：
Respirogram technology has been widely applied for aerobic process,however,the response of respirogram to anoxic denitrification is still unclear.To reveal such response may help to design a new method for the evaluation of the performance of denitrification.The size dis-tribution of flocs measured at different denitrification moments demonstrated a clear ex-pansion of flocs triggered by denitrification,during which higher specific endogenous and quasi-endogenous respiration rates(SOURe and SOURq)were also observed.Furthermore,SOURq increases exponentially with the specific denitrification rate(SDNR),suggesting that there should be a maximum SDNR in conventional activated sludge systems.Based on these findings,an index Rq/t,defined as the ratio of quasi-endogenous(OURq)to maximum respi-ration rate(OURt),is proposed to estimate the denitrification capacity that higher Rq/t indi-cates higher denitrification potential,which can be readily obtained without complex mea-surement or analysis,and it offers a novel and promising respirogram-based approach for denitrification estimation and control by taking measures to extend anoxic time to maintain its value at a high level within a certain range.
