According to water quality and sewage discharge characteristics and combining the self-excited oscillation pulsed jet aerator work performance, the pulse jet aerated cyclic reactor(PJACR) is developed. It can not only realize the intermittent aeration, but also produce pulse jet aeration in the aeration process. The experiment shows that the aerator can realize bubble ultra-micronization and enhance the range, so it improves the aeration efficiency and actuating range; Under these conditions, hydraulic load...
