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.
