STUDY ON TREATING THE HOSPITAL SEWAGE WITH CHLORINE DIOXIDE

In this paper, the disinfection effect of chlorine dioxide (ClO2) on the hospital sewage is studied by numerous experiments for the first time. The killing effect of ClO2 on bacteria and coliform group bacteria and the effect of ClO2 on removal of organisms are researched systematically under various conditions such as the dose of disinfectant, the contact time and pH value,and it is compared with that of liquid chlorine. The results show that killing effect of ClO2 on microorganism and the effect of ClO2 on removal of organism are better than that of liquid chlorine,and sewage treated by using chlorine dioxide is accorded with and met the National Effluent Standard. Simulataneously,disinfection effect of ClO2 on those bacteria as well as separation and determination of bacteria in the hospital sewage are carried out. It's also testified that disinfection effect of chlorine dioxide is better than that of liquid chlorine. All the results prove that the application of chlorine dioxide to hospital sewage treatment is feasible.
