In thisstudy, two lab-scale sequencing batch reactors (SBRs) were used for thetreatment of municipal wastewater at low temperature (15oC). TheseSBRs were a C-SBR (control SBR) and a Z-SBR (zeolite SBR). Both reactors were operatedin similar conditions, except for addition of zeolite in the Z-SBR. The resultsshowed that the average COD, TN, NH4+-N and TP removalwere 90%, 53%, 88% and 93% in Z-SBR compared with 90%, 35%, 75% and 93%. Theresults of COD removal showed that there was no significant difference betweentwo reactors. Z-SBR had better removal capability of nitrogen than C-SBR. Z-SBRexhibited same TP removal with the C-SBR. A higher MLVSS concentration andlower SVI values were observed in Z-SBR compared to that of the C-SBR. Theaverage MLVSS concentration for Z-SBR and C-SBR is 2900 mg l-1 and2120 mg l-1, respectively. The SVI values were lower in Z-SBR (80-100 mL g-1) than C-SBR (120-140 mL g-1).The highest NH4+-N removalefficiency was observed at pH value of 8.0. It was found that zeolite additioninto SBR lessened the negative influences of low temperature and positivelyaffected the performance and sludge settling capability. This work showed thatthe Z-SBR is an efficient modification of the activated sludge process forco-removal of organic matter and nitrogen at low temperature. |
