The immobilization of effective microorganisms (EM) on matrix supports is of great importance for improving microbes’ density and avoiding microbes flooding so as to enhance removal efficiency in polluted river water. What’s more, DO is of great importance in the wastewater treatment. Based on the previous study, the effects of dissolved oxygen (DO) on the activities of EM and IAEM (minerals adsorbing EM embedded by sodium alginate) were also investigated in polluted river water. The results showed that with abundant DO, removal efficiency of NH3-N, TP and COD for EM and IAEM were increased by (34.34%, 18.18%, 4.59%) and (5.71%, 5.06%, 2.79%), which demonstrated EM alone was more adaptive to survive and reproduce under aerobic conditions, while immobilized microbes could better overcome the limitation of DO.
