The wave-transparent water tank 1 is vertically arranged, and mainly when the amount of sewage to be treated existing in the upper-section sewer 13 is not large, the wave-transparent water tank 1 serving as a sewage container can also be stored and treated. On the contrary, if the area of the horizontal cross section of the wave-transparent water tank 1 is too large and the amount of the sewage to be treated existing in the upper sewer 13 is not large, the sewage accommodated in the wave-transparent water tank 1 is difficult to submerge along with the bottom of the wave-transparent water tank 1, which is obviously undesirable. In addition, if the area of the horizontal section of the sewage container is too large, the sewage container also occupies a large space, and is not favorable for indoor installation.
As shown in fig. 3, the sewage container is provided with an inlet for sewage to enter and discharge, which is an inlet for sewage to enter and discharge provided in the wave-transparent water tank 1, and the inlet for sewage to enter and discharge is provided at the bottom of the wave-transparent water tank 1.

After the sensor for reflecting the height information of the sewage level in the wave-transparent water tank 1 collects the height information of the sewage in the wave-transparent water tank 1, the following work is carried out in sequence by a relevant controller: according to the height of the sewage liquid level in the wave-transparent water tank 1, the corresponding microwave generators 6 are started by the controllers of the corresponding number of microwave generators 6, so that the microwave generators 6 emit microwaves to the waveguide cavity 4, and the sewage in the wave-transparent water tank 1 is inactivated; after the sewage inactivation treatment is finished, the two-position three-way electromagnetic valve 11 controller is switched to a positive pressure position by the two-position three-way electromagnetic valve 11 controller, and the fan 12 is started by the fan 12 controller to enable positive pressure to be formed in the wave-transparent water tank 1; the water outlet check valve 91 is opened by the controller of the water outlet check valve 91, so that the sewage which is subjected to inactivation treatment in the wave-transparent water tank 1 is flushed out of the wave-transparent water tank 1 under the action of air pressure and flows into the lower-section sewer 14 through the water outlet branch pipe 9; fan 12 is turned off by fan 12 control.
As shown in fig. 1 and 3, the device for inactivating pathogens in domestic sewage by using microwaves of the present invention has the following two application methods:
firstly, the sewage in the upper sewer 13 is instantly pumped into the wave-transparent water tank 1 under the action of the negative pressure formed in the wave-transparent water tank
In the water tank 1, when the sewage in the wave-transparent water tank 1 is accumulated to a set amount, the sewage is inactivated and discharged. That is, sometimes the sewage in the upper sewer 13 is not much, the sewage in the upper sewer 13 is pumped into the wave-transparent water tank 1 for many times (more than two times), and the inactivation treatment is performed once again after the sewage in the wave-transparent water tank 1 has a large storage amount. This is equivalent to the wave-transparent water tank 1 serving as a temporary dirt storage before inactivation is carried out. The purpose is that the sewage can not be left in the upper sewer 13, so that the sewage is not unsightly and has peculiar smell.
And secondly, the sewage in the upper sewer 13 is instantly pumped into the wave-transparent water tank 1 under the action of negative pressure formed in the wave-transparent water tank 1, and is discharged from the wave-transparent water tank 1 after being subjected to inactivation treatment in time. Namely, the sewage in the upper sewer 13 is treated and discharged in time no matter how much sewage is in the upper sewer 13, so that the sewage is not remained in the upper sewer 13 or the wave-transparent water tank 1.
The above embodiments are only for the purpose of more clearly describing the invention and should not be considered as limiting the scope of protection covered by the invention, any modification of the equivalent should be considered as falling within the scope of protection covered by the invention.
