We suggest that UV applied wastewater and treated water for the experiments in sanitary engineering of 4th grade student in department of civil engineering. The safety management was concerned for sanitary conditions. The results of water quality using some analyzers is not affected by UV radiation. The similar data were obtained at 7 kinds of water quality analysis, when we used wastewater and treated water from the septic tank. However, the difference of COD and NH4-N data used UV radiation were a little higher as compared with wastewater and treated water data. The method of explanation for using UV radition has to be improve. These results Indicate that using the artificial wastewater on experiments for students in sanitary engineering has a few improvement.
