超声对印染废水的可生化性研究

An Analysis on Biodegradability of Dyeing Wastewater under Ultrasound Condition

利用超声波降解水中的污染物是近年兴起的新工艺。研究了超声波对印染废水可生化性的影响,实验结果表明:超声使印染废水生化性有所提高,特别是在稀释后超声生化性提高显著,而曝气加超声后提高较小。

Ultrasonic is a new technique to destroy organic polluntants in water in nowsday. The infection of biodegradability of dyeing wastewater under ultrasound wave condition was analysed in this paper. The results of experiment indicate that the degradability was increased under ultrasound condition , specially when it was diluted. Biodegradability was increased a little under aeration and ultrasound.
