| Abstract: | To study the effect of impinging stream technology on the degradation of organic pollutants in wastewater by advanced oxidation,numerical simulations were performed to study the flow characteristics of gas and water impinging streams through the FLUENT software by controlled volume numerical analysis.A two-phase-fluid mathematic model of k 1-ε 1-k b-ε b method was also established to further study the flow characteristics of a two-phase-fluid impinging stream.The simulating results showed that strong turbulent flow is formed during the impinging process which provides excellent conditions for mass transfer intensification.The strong mutual-permeability of gas and water also indicated that the impinging stream technology is effective and viable to intensify the mass transfer process of wastewater treatment by advanced oxidation. |
