According to the above study results, especially the steady operation of two-sludge system（2A/O+N 2SBR）, it can be proved that denitrification and excess phosphorus uptake are relatively independent and intersectant biological processes. The overlap is that denitrifying phosphorus removing bacteriawhich possesses the two bacterial metabolisms, could utilize nitrate as an electron acceptor for phosphorus uptake. The two-sludge system can not only combined biological phosphorus removal and denitrification processes to form a process in practical wastwater treatment , but also solved the main difficulties of current single-sludge systems:①the sludge age competition between phosphorus removing bacteria and nitrifier;② the substrate competition between denitrification and dephosphatation.

To assess the thermal contribution from oxidation reaction, the standard formation enthalpes of all reactants and products were used to calculate the oxidation enthalpies. It could be found that all oxidation reactions were exothermic. And oxidation played a more important role during the toluene trinitration at high temperature, because the reaction temperature of toluene trinitration is the higher than mononitration and dinitration, and the temperature coefficient of oxidation is higher than that of trinitration too.

Experimental results showed that, in this process, the optimal pH of the shortcut nitrification was 8.0～8.5; when the pH was less than 6,the nitrification is completely inhibited; when the pH was 6～7, at the end of aeration, the Nitrobacteria become the dominant bacteria because of the dropping of the free ammonia concentration. It is known to all, the activity of the Nitrobacteria and Nitrosomonas was affected by FA concentration, so nitrification was affected by FA concentration. According to the author's research results, the FA concentration which inhibit the Nitrobacteria was below 1.0mg/L,which inhibit the Nitrosomonas was above 10mg/L.
