D
egradation of contaminants present in residual water using TiO
2
/ZnO catalysts (D-TiO
2
/ZnO): It is an experimental work
which aims to degrade the contaminants present in the water from a municipal wastewater treatment plant. This objective
is achieved through the use of UV radiation and TiO
2
/ZnO catalysts. The catalysts used were synthesized using the sol-gel
method. The sol-gel method was chosen for the synthesis because this method achieves a high homogeneity and purity of the
materials besides presenting a great thermal stability. Once the catalysts were obtained their characterization was carried out
by the methods of X-ray diffraction, scanning electron microscopy and energy dispersive spectroscopy. Degradation tests are
carried out on the wastewater with the catalysts and an 850mL batch photoreactor composed of a medium pressure mercury
vapor lamp which emits ultraviolet radiation with a region between 200-400nm. To follow up the photodegradation, samples
were taken and analyzed in a UV spectrophotometer. Physico-chemical, microbiological and genotoxicity analyzes are carried
out before and after photodegradation to compare the results and verify that the degradation has been successful. The results
of the tests showed an evident decrease in the color, turbidity, solids, heavy metals, chemical oxygen demand and biological
demand of oxygen present in the residual water sample.
