Apart from residential sewage, hospital sewage, especially that from contagious wards, also contains chemical substances, radioactive wastewater and pathogens, so it must be disinfected before draining. The sources and the components of the hospital sewage are sophisticated. Such sewage contains deleterious pathogenic microorganisms, poisonous chemical substances and radioactive pollutants, with hazardous characteristics such as acute contagion and latency contagion. Unless it’s effectively treated, it will seriously pollute the environment and lead to a new way of spreading disease.
