超声波处理活性污泥细胞破壁脱水研究

利用超声波破碎活性污泥中的细胞壁,使细胞的胞液渗出,达到污泥干化的目的。通过研究利用超声波处理剩余活性污泥的原理,不同条件因素对处理效果的影响,以及处理后活性污泥性质的改变情况。将来,随着科学技术的发展和对超声波技术研究的深入,利用超声波处理活性污泥的方法将日趋成熟。超声波作为一种清洁的手段一定会广泛应用于废水的处理工程中,为经济的持续发展和资源环境的保护服务。

Research on Active Sludge Cell Broken- down Wall dehydration using Ultrasonic Wave

This study use ultrasonic wave to break to cell wall of active sludge, drying the sludge by letting the butcher fluid in the cell to seep out. This paper studies the principle measures in treating excess activated sludge by the ultrasonic wave, the effects of different factors on the treatment effect, and the propriety changes after the treatment of activated sludge. With the de- velopment of science and technology, in depth study of ultrasonic technology, the method for treatment of activated sludge using ultrasound will become more mature in the future.
