Abstract

Hospital wastewater containing phenol as a disinfectant in hospital activity. Safe for the environment if the phenol concentration ranged from 0.5 to 1.0 mg / L in according with KEP. 51/MENLH / 10/1995. Purpose of the study to analyze the ability of anatase TiO2 photocatalysts in the degradation of phenol in wastewater and wastewater artificial general hospital (RSUP) Dr.M. Djamil Padang, the optimum volume, optimum irradiation time and optimum concentration of phenol. This research involves determining the optimum volume, irradiation time and the optimum concentration of phenol in wastewater optimum artificial and apply to the wastewater general hospital of Dr.M. Djamil Padang. The results on artificial samples showed the highest phenol degradation occurs in 250 ml volume, long irradiation with UV-C Philips 2.5 hours and 3.5 ppm concentrations of phenol, phenol removal efficiency which reaches 98.03% with the number of phenol remaining in the waste of 0.069 mg/L. In experimental applications using wastewater Dr.M. Djamil Padang with volume, length of exposure and concentration of phenol is similar with artificial wasteswater, phenol removal efficiency reached 86.21% with the remaining amount of phenol in wastewater at 0.483 mg/L. Keywords: degradation, phenol, anatase TiO2 photocatalysts, waste Dr.M. Djamil Padang.
