Disinfection of simulated sewage by neutral calcium hypochlorite (Hi-Chlone) was examined. 1. COD values of peptone solution were adjusted to those of the supernatant and muddy of sewage. E. coli was incubated at 37℃ in the peptone solution. 2. After addition of calcium hypochlorite to peptone solutions in vorious concentration, chlorine demand, time course of residual chlorine, chemical and biochemical oxygen demand were determined and the effect of Hi-Chlone on E. coli was investigated. 3. In any concentrations of peptone solution, adding 25% of available chlorine to chlorine demand in medium was fairly effective on disinfection of E. coli and it was not considered that such addition had post-effect of sewage digestion because of the disappearance of chlorine after 16 hours.
