Study on SRT Influence to Phosphorus Removal and Sludge Characters of HA-A/A-MCO Process

Abstract:

Extended SRT (sludge retention time) is helpful to improve ability of anaerobic phosphorous release and chemical recovery of phosphate, yet phosphorous removal efficiency will not be affected. Extended SRT makes the system to have even more active sludge, it also can lead to the system have powerful ability of biochemical reaction by using superiority of concentration, meanwhile, extended SRT can still reduce sludge yield. Extended SRT can not make SMP(soluble metabolic products) accumulate in the reactor so that pollutants removal power is reduced, it also cannot affect the activity of sludge. However, extended SRT will be able to make coagulation of sludge hard, SVI value increase, yet it cannot cause sludge bulking.
