Abstract: Heterogeneous photocatalytic degradation of organic contaminants has attracted m uch attention of both scientists and engineers around the world. Up to now the o ptimum photocatalytic reactor design is the most significant unresolved issue. I n the present paper,a novel reactor design for the use of titanium dioxide-co ated glass-springs is developed for photocatalytic purification and treatment of water and air.The manufacture of the coating of the glass-springs is discusse d in detail.An experimental device was designed for testing the radiation intens ity distribution of gas-solid photocatalytic reactor.The model parameters of the extended two-flux model were measured,then radiation intensity distribution in side the reactor was computed.The experimental results agreed with the model-com puted results.Moreover,the radiation intensity distribution and the total radia tive energy absorption rate were described by the above-mentioned model in gas-s olid parallel-plate reactor packed with the photocatalyst supported on glass-springs.
