The granulation of anammox sludge plays an important role in the high nitrogen removal performance of the anammox reactor. In this study, anaerobic granular sludge was selected as the seeding sludge to start up anammox reactor in order to directly obtain anammox granules. Results showed that the anammox UASB reactor was successfully started up by inoculating anaerobic granular sludge, with substrate capacity of 4435.2mg/(L⋅d) and average ammonium and nitrite removal efficiency of 90.36 % and 93.29%, respectively. During the start-up course, the granular sludge initially disintegrated and then reaggregated and turned red, suggesting the high anammox performance. Zn-Fe precipitation was observed on the surface of granules during the operation by SEM-EDS, which would impose inhibition to the anammox activity of the granules. Accordingly, it is suggested to relatively reduce the trace metals concentrations, of Fe and Zn in the conventional medium. The findings of this study are expected to be used for a shorter start-up and more stable operation of anammox system. 1.

Novel one-dimensional Mo3O10(C6H8N)2 · 2H2O nanobelt have been prepared by a facile method. SEM and TEM show Mo3O10(C6H8N)2 · 2H2O has 1D nanobelt morphology and good dispersion. The Mo3O10(C6H8N)2 · 2H2O nanobelt can prevent the reaction of Mo3O102 − with the proton and improve the conductivity because of 1D structure and the composition of (C6H8N)2 molecules. After being measured the properties for hydrogen evolution reaction, 1D Mo3O10(C6H8N)2 · 2H2O demonstrates better electrocatalytic activity and stability for in acidic electrolyte compared with MoO3. It can be speculated that both 1D nanostructure and amine coating on Mo3O10(C6H8N)2 · 2H2O nanobelt play crucial role for improving the electrocatalytic activity.
