摘　　要：研究了超声波破解污泥的情况。在超声波单独作用及超声波/碱作用下,测定SCOD(溶解性COD)的量,分析超声波、超声波/碱对污泥破解的效果。结果表明,从镜检中可以看到,污泥絮体随超声波作用时间的延长越来越散;SCOD随超声波作用时间的延长而增加;超声波与碱协同作用对污泥的破壁效果比超声波单独作用好。Sludge cell disintegration is studied by using ultrasonic wave in this article.The effect of ultrasonic wave and ultrasonic/alkali are analyzed by testing the concentration of SCOD.The result shows that from the microscope sludge floc is more and more looser with increase of ultrasonic wave retention time; SCOD concentration rises with ultrasonic wave action time; the breaking effect to sludge by using ultrasonic wave combined with alkali is better than that by ultrasonic wave alone.

关 键 词：超声波 破解 污泥 SCOD
