Description

Technical Field

[0001] The utility model relates to the technical field of wastewater disinfection, in particular to a domestic and medical wastewater disinfection device. Background Art

[0002] Wastewater disinfection is a water treatment process that uses disinfectants to kill harmful pathogenic microorganisms in domestic sewage or medical wastewater. Domestic sewage and medical wastewater contain a large number of bacteria, viruses, cysts, etc. After traditional secondary biochemical treatment, only about 90% of E. coli can be removed. In order to prevent the spread of diseases, wastewater disinfection equipment is required to disinfect the wastewater after secondary biochemical treatment.

[0003] The publication number "CN210945186U" provides a medical waste water disinfection device. Through the setting of a filter box and a filter net, personnel can pass the medical waste water first when disinfecting it. The filter net intercepts large particles of debris, thereby greatly reducing the blockage, so that personnel can conveniently clean the disinfected waste liquid, and it is also easier to disinfect the waste water. At the same time, through the setting of a sediment cleaning port, personnel can open the sediment cleaning plug when cleaning the sediment produced by disinfection, thereby facilitating personnel to clean the sediment.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] The medical wastewater disinfection device has a single disinfection structure and only relies on a disinfection lamp to disinfect the wastewater. In actual use, it cannot effectively kill most of the bacteria and viruses in the wastewater, and thus cannot meet the disinfection needs for domestic and medical wastewater. The disinfection effect needs to be improved. Utility Model Content

[0033] Embodiment 2:

[0034] On the basis of Example 1, in this embodiment, by opening the second valve 71, the wastewater in the first disinfection box 1 can flow into the second disinfection box 6 through the guide pipe 72, and then the multiple ultraviolet disinfection lamps 74 are operated to perform secondary disinfection on the surrounding wastewater. In this process, the staggered first partitions 75 and the second partitions 76 can extend the flow path of the wastewater in the second disinfection box 6, so that the multiple ultraviolet disinfection lamps 74 can fully disinfect the passing wastewater, thereby killing most of the bacteria and viruses in the wastewater.

[0037] Working principle: the staff first opens the inlet valve 53 to allow the domestic and medical wastewater to flow into the filter barrel 5 after sedimentation. At this time, the filter basket 52 can block and filter most of the insoluble impurities in the wastewater, and the filtered wastewater will flow into the first disinfection box 1. When the wastewater level in the first disinfection box 1 reaches the required height, the inlet valve 53 can be closed to prevent the domestic and medical wastewater from continuing to flow into the filter barrel 5; at this time, the staff will then put an appropriate amount of sodium hypochlorite disinfectant into the first disinfection box 1 through the delivery bucket 3. After the delivery is completed, the sealing cover 51 is mounted on the upper end of the delivery bucket 3 to prevent the first disinfection box from 1, the odor inside the first disinfection box 1 is dispersed to the outside, and then the low-speed motor 41 can be started, so that the low-speed motor 41 drives the transmission vertical shaft 47 to rotate through the transmission gear 43 and the driven gear 44, and the transmission vertical shaft 47 drives the stirring rod 49 and the stirring support rod 48 to rotate together, so as to stir and mix the wastewater and the sodium hypochlorite disinfectant in the first disinfection box 1, so that the sodium hypochlorite disinfectant can disinfect the wastewater once; at the same time, the external ozone generator is started and the first valve 46 is opened, so that the ozone gas passes through the air guide pipe 45, the air guide cavity 414, the connecting cavity 413 and the one-way valve 412 in sequence into the nozzle 411, and then passes through the nozzle 4 11 is sprayed downward into the wastewater to kill bacteria, viruses, fungi, protozoa and oocysts, so as to further disinfect the wastewater. When the wastewater in the first disinfection box 1 is disinfected for the required time, the low-speed motor 41, the external ozone generator and the first valve 46 can be turned off; then the second valve 71 is opened to allow the wastewater in the first disinfection box 1 to flow into the second disinfection box 6 through the guide pipe 72. At this time, the staff can operate multiple ultraviolet disinfection lamps 74 to perform secondary disinfection on the surrounding wastewater, and in this process, the staggered first partitions 75 and the second partitions 76 can extend the wastewater in the second disinfection box 6. The flow path of the wastewater is cleared so that multiple ultraviolet disinfection lamps 74 can fully disinfect the passing wastewater (in this process, the staff will cover the observation window on the front end of the blocking baffle 62 with anti-ultraviolet fabric in advance to prevent ultraviolet rays from irradiating the outside through the observation window and harming the surrounding staff). When the wastewater in the second disinfection box 6 is secondary disinfected for the required time, the staff can turn off the multiple ultraviolet disinfection lamps 74 and open the discharge valve 61 to discharge the wastewater in the second disinfection box 6. When all the wastewater in the second disinfection box 6 is discharged, the above operation can be repeated to carry out the disinfection treatment of the next batch of domestic and medical wastewater.
