| 摘 要： | 试验选取超声波声能密度,超声时间、超声间隔3个因素没计正交实验,研究了超声波对城市污水剩余活性污泥(WAS)的缺氧/好氧消化的作用.结果表明,经超声辐照的WAS缺氧/好氧消化9天后,MLVSS去除率最高达50.9%,比未经超声辐照的提高了14.4%.对实验结果的分析表明,超声波强化WAS的缺氧/好氧消化的最佧参数为:超...

| Abstract: | An experimental program of orthogonal design was done to determine the most effective treatment conditions of the ultrasonic density,time and interval on the anoxic/aerobic digestion of waste activated sludge(WAS).Results showed that the maximum removal rate of MLVSS reached 50.9% after 9d digestion with ultrasonic treatment,14.4% higher than that without ultrasonic treatment,and the optimal treatment conditions were ultrasonic density at 0.15W/mL,ultrasonic time at 10min,ultrasonic interval at 12h.Under th... |
