The CANON process has the disadvantages of long start-up periods and unstable operation. In the SBAF system, under strictly controlled conditions of dissolved oxygen (DO) and temperature, a CANON process is started up in 51 days and is operated stably for 278 days using a new method of independent research and development. The results show that the maximum and average ARR are 98.9% and 95.1%, respectively. The maximum and average TNR are 85.9% and 75.1%, respectively. Furthermore, a small quantity of nitratenitrogen exists in this system. The microbial structure features of the sludge are analyzed by 16S rDNA macro high-throughput genome sequencing. It is verified that Proteobacteria is the main microorganism in the AOB, and Planctomycete |
