For the disinfection of hospital sewage, at present at home and abroad mainly uses liquid chlorine, bleaching powder (or bleach), sodium hypochlorite, ozone and chlorine dioxide. With chlorine dioxide and chlorine in hospital sewage disposal, disinfection experiment. The effects of chlorine dioxide on hospital sewage treatment effect, Shandong Gaomideng Shun Chemical Co., Ltd., the following conclusions are drawn:

1) the effect of chlorine dioxide on the killing effect of the disinfectant identified by the State shall be remarkable and highly effective, and in line with the requirements of the Ministry of public health.

2) of chlorine dioxide on the isolation and identification of out of hospital wastewater disinfection effect of non pathogenic bacteria and pathogenic bacteria was better than chlorine.

3) chlorine dioxide can effectively kill bacteria (E. coli) in hospital sewage in the range of ph=3.0-9.0, and the chlorine can only achieve satisfactory results in neutral condition.

4) the removal effect of COD and BOD5 is better than chlorine dioxide in hospital sewage.

5) suggested that chlorine dioxide treatment sewage of hospital operating parameters are: dosage 30-50mg/l, 60-120 min; under these conditions, the processing after the total number of bacteria in the sewage can be reached GB48-83 national hospital sewage discharge standards and using the national sewage integrated emission standard of.
