Background
Generally, in the construction process of hospitals, infectious disease wards and ordinary wards are separated, and sewage is separately collected; infectious disease wastewater generally comes from places such as laboratories, operating rooms, sickrooms, laundries and the like. The infectious disease waste water may contain a large amount of viruses and germs, so if the infectious disease waste water is not treated properly, the infectious disease waste water will have great influence on the external environment. In order to ensure that infectious disease germs do not propagate in a sewage treatment system in a large quantity, the wastewater is required to be disinfected in advance; the disinfection technology adopted is generally chlorine disinfection. However, the wastewater at this stage has various and high concentrations of pollutants, and the pollutants consume a certain amount of disinfectant, so that the disinfectant requires a large amount of investment; the addition of a large amount of chlorine disinfectant not only brings serious odor to the wastewater, but also brings fatal influence to a subsequent biological treatment system.
Therefore, the conventional infectious disease wastewater treatment method always has the contradiction: the front end is disinfected well, and other indexes of the rear end do not reach the standard; the front end is not disinfected in place, and the rear end operating personnel have the risk of infectious disease pollution.
Therefore, the technology for realizing disinfection and simultaneous pollutant removal at the front end is found in the infectious disease wastewater, and the fundamental solution to the contradiction is achieved.
