Résumé:
On this research was proposed a process that, besides a relatively cheap cost, could lead an efficient degradation and a full removal of fenton by the addition of two processes: the oxidation of photo- fenton on natural light and artificial UV with absorption of activated coal. Also were analysed Isotherm of absorption and cinematics of absorption, as with only the activated coal as with the hybrid system of activated caol with POAs photo-feton natural light and artificial UV, and investigate DQO, color, turbidity, electric conductivity, PH, the influence of Fenton concentration in different times, influence of activated coal mass, all with a batch system. The POA photo-fenton artificial light of UV plus absorption with activated coal, got better removal of DQO = 81, 49%, with the final concentration of 24, 52 my/L, being the result more close to the Conona resolution 430/2011, in which the maximum acceptable final concentration of fenton of 0,5mg/L. All the cinematic absorption experiments were better represented by the pseudo- second order, in relation as isotherm of absorption the best experiment results were represented by the Langmuir method.
