Abstract

Abstract

Pulsed electric field is mainly used in food and medical sterilization, and its widely recognized sterilization mechanism is electroporation theory. Based on that, the pulsed electric field at low voltage and frequency can not only change the permeability of cells, but also ensure that the cells can not be inactivated. In order to explore the influence of pulsed electric field on the denitrification effect of ANAMMOX, different types of electric fields were applied in the constructed reactor respectively. The concentration of influent and effluent NH₄⁺-N and NO₂^--N and the microbial cell structure were taken as the detection indexes to investigate the denitrification effect under various conditions. The results showed that the pulsed electric field group could effectively maintain the stability of the ANAMMOX reaction, and the TN removal rate reached more than 80%, which was 60% and 20% higher than the TN removal rate in the DC electric field group and the blank group respectively. At the same time, the microorganism structure of pulsed electric field group was more complete than that of the DC electric field group and blank group. The results showed that the pulsed electric field could effectively promote the denitrification effect of ANAMMOX and maintain the running stability of the reaction system.
