Performance Bioaugmentation of Nitrogen Removal in Solid-phasedenitrification Based on Microbial Quorum Sensing Mediated by AHLs
Solid-phase denitrification(SPD)process with polyhydroxybutyrate valerate copolester(PHBV)as the carrier and biodegradable carbon source,and the quorum sensing signal factor 3-oxo-C14-HSL was added as the regulator to analyze the performance of reverse nitrification from the characteristics of the water quality.The results show that the starting time of the reactor can be effectively shortened by adding the quorum sensing signal 3-oxo-C14-HSL.And in the stable operation stage,the denitrification rate remains unchanged.During the long-term operation of the reverse nitrification,nitrite did not accumulate.This study will provide new ideas and theoretical basis for the study of quorum sensing in the field of biological denitrification.
