Özet:

The effectiveness of the uses of ultrasonic cavitation for wastewater treatment has been investigated. The influence of the gases of different nature (nitrogen, oxygen, air, mixture of nitrogen and oxygen gases in the ratio of 1:1) on the destruction of organic and biological contaminants has been carried out. It is confirmed that ultrasound cavitation increases the purification effect of gases. It is established that the deepest purification from organic contaminants was achieved by the common action of air with ultrasound, the degree of water purification from organic compounds being 80% and from biological contaminants – by the common action of nitrogen with ultrasound – the degree of water purification from biological compounds being 99,5%. The effective rate constant was calculated.
