Design and simulation of novel rotating cylinder photocatalytic reactor

A rotating cylinder photocatalytic reactor was designed and assembled,and the measurement of illumination distribution,as well as the degradation experiments of 4BS dye solution in batch operation were performed.After data processing and mathematical derivation,a design equation of the reactor was established.The degradation rate equation included the influences of the concentration of solution,and the amount of catalyst,UV intensity,pH and area of illumination,and water treatment in the photocatalytic reactor was simulated.The simulation result agreed with experimental data and could be used for the scale up of such reactors.
