【 摘 要 】

In this work, the performance of the concentrates such as settleability, particle size distribution and filterability at different ultrasonic treatment was investigated and compared in the high loaded bioflocculation-membrane reactor for actual municipal wastewater treatment. The results indicated that the ultrasonic treatment can effectively improve the settleability of the concentrate. Moreover, the concentrate treated with the different ultrasonic, the particles in the concentrate were broken and distributed in small size interval. What needed to be noticed that when the concentrate with ultrasonic intensity of 0.6 W/mL treatment, found that membrane filtration resistance was highest.
