Study of the Treatment Technology for Photocatalytic Degradation of unsymmetrical dimethyl hydrazine (UDMH) wastewater

摘要

The photocatalytic degradation of UDMH wastewater in fixed bed by catalyst of TiO_2 with UV lamp has been studied, and the equipment with which to support TiO_2 catalytic material and UV system has also been finished. The feasibility of photocatalytic degradation of UDMH, with supported TiO_2 as catalyst, is satisfied. The effect of adding Cu~(2+), H_2O_2, or bubbling air can enhance the degradation rate of UDMH. Moreover, the equipment is mechanically and chemically stable, and the fixed TiO_2 can be reused.
