| The massive waste water and the waste can be discharged from hospital outpatient clinic, in-patient department as well as the quarters; There are many bacteria, virus and eggs of parasite, as well as heavy metals ,disinfectors, organic solvents ,acids ,alkalis , radioactive and so on in the waste water. So the hospital waste water discharging into waters without reasonable disposal will endanger environment and jeopardize health of human being in long-term. Disinfection is the key of the hospital waste water treatment because of its special property. Deeply analysis and research on the disinfection of hospital sewage are done in this paper. The disinfection of low energy and high efficiency, function stabilization and without second pollution is studied with emphasis. And conclusion was drawn by intercross experiment. In the system of UV-H2O2, The amount of H2O2 added in this experiment impose a most distinct influence on the experimental result. The intensity of ultraviolet radiation takes second place .The influence of the disinfectant time is not notable. Optimum running condition of the UV-H2O2 and degradation organic substance is the intensity of ultraviolet 134.1 μ W/cm2 , The amount of H2O2 100mg/l, Settle time 10min. At the same time, the process is designed taking the example of the FuXin mining group hospital .The optimum craft being determined is the process of disposal effect stabilization, adjusting deposition + hydrolyze + contact-oxidation + UV-H2O2,which provide theoretical basis and technological support for compositive hospital sewage Treatment study.
