영문 초록

The hospital wastewaters have to be so disposed as to prevent disease and to protect water resources from hazardous substances; disinfectants, medicines, and chemicals. Polyvinylpyrrolidone-iodine complex (po꺼done-iodine) is widely used in the hospital as one of disinfectants. πùs study was carried out to manifest the effect of disinfectants in growth of activated sludge in treatment of the hospital wastewater by the activated sludge process. The results are as follow. 1. An average water quality of the hospital wastewater showed 7.2 in pH, 3.2 ppm in 00, 293.3 ppm in SS, 96.0 ppm in 800, 151 .1 ppm in COO, 0.4 ppm in povidone-iodine, 0.5 ppm in phenols, 5.4 ppm in surfactants, 1.6 ppm in o-phosphate, 4.6 ppm in NH3 -N, 249 x 104 counts/l00 mQ in coliform group organisms, and 1,369 x 101 counts/mQ in general counts of bacteria. And wastewater amounts discharged per bed was ca1culated 70 Q/d/bed. 2. In batch culture activated sludge process, each of cresol and podone-iodine was not effected in less than 0.1 ppm concentration, but the more concentration, the more inhibit the growth rate of activated sludge. In the mixture of two disinfectants, the growth was more inhibited the effect of single disinfectants. So that this reaction is considered as addition effect of two disinfectants. 3. The removal rates of the disinfectants by continuous cu1ture activated sludge process were 77 .6% in 0.4 ppm povidone-iodine, and in 80D was 85.6%. 4. It is desirable that the hospital wastewater is planed in order to be discharged to two system separately, sewer from life system and wastewater from medica1 system. From those results, it has been conc1uded that the hospital wastewater has to be treated safely by the activated sludge process.
