영문 초록

A concentrated evaporation experiment was carried out in this study, to find out the removal and concentrating efficiency of heavy metals from concentration process as well as analysis and investigation for the characteristics of the condensed water. In the experiment of wastewater treatment from X -ray film by using concentrated evaporation, the results show that COD removal efficiency rate was more than about 99%, the major toxic metals, including Pb, CN, F, Zn was almost removed. It could be seen that the early boiling point of each wastewater was 108.5℃ for the wastewater of the fixing solution, 106.7℃ for the wastewater of developing solution and 107℃ for the mixture(1:1) of both wastewater. The increasing rate of boiling point was the greatest in the wastewater of the developing solution and the mixture and the wastewater of fixing solution in descending order. The boiling point under 1atm in a vacuum was 30℃ for the wastewater of the developing solution, 37℃ for the wastewater of the fixing solutions, and 35℃ for the mixture.
