摘要

The slow start-up of anammox process has been a big obstacle for its engineering application. In this study, a new strategy was adopted to start up anammox by mixing perchlorate reduction sludge (PRS) and anammox sludge with 50:1 vol ratio, and the mechanism in the start-up process was explored. The results showed that anammox process was started up successfully after 41 days. During the operation process, pH value increased from 7.88 +/- 0.14-8.06 +/- 0.11, extracellular polysaccharides (PS) increased from 10.56 to 24.45 mg.(g VSS)(-1), C6-HSL increased by 0.061 mu g.(g VSS)(-1), and C8-HSL decreased by 0.068 mu g.(g VSS)(-1). These changes in favor of anammox were attributed to the contribution of PRS and the guidance of anammox sludge. The bacterial ecology evolved towards anammox. This study provided a new idea for the anammox start-up in practical application.
