Abstract
The present invention discloses a non-diffusion full-sealed hospital sewage treating system which has the functions of sterilization, disinfection and prevention of proliferation of germs. The system belongs to a technical range of sewage disposal, and is mainly composed of an airtight grid, a regulation tank, a high efficiency membrane bioreator, a high efficiency broad-spectrum ultraviolet sterilizer, which are serially connected. An entire system adopts a full-sealed structure. All gas discharged by the membrane bioreator, the regulation tank and the grid enters an independent ultraviolet sterilizer through a pipe for disinfection, and germs can be prevented from being diffused outside through the gas. The sludge output of the membrane bioreator is very less, and basically, no sludge is discharged; the interference of the suspended substances in the waste water to ultraviolet disinfection is eliminated, and the high efficiency function of the ultraviolet disinfection is fully exerted; the probability of diffusion and the spread of pathogenic bacteria through the discharging of sludge is greatly reduced. Various indexes of effluent water processed by systems all reach the emission standard GBJ48-83 of hospital sewage of China or are superior to the emission standard GBJ48-83 of hospital sewage of China.
