The middle area of the diversion cover 4 is a closed structure, and the sewage cannot directly enter the upper space of the medicine spraying chamber 2 through the middle of the diversion cover 4, ensuring that the sewage can be dispersed at the small end of the cone of the diversion cover 4.
[0026] When spraying the medicine, the medicine adding pump 8 pumps the medicine into the inside of the medicine spraying chamber 2. At the same time, the sewage enters the inside of the medicine spraying chamber 2 through the water inlet 201. The sewage and the medicine are mixed inside the medicine spraying chamber 2. The sewage and the medicine first converge together through the large round hole in the middle of the confluence cover 3 and enter the upper part of the confluence cover 3. Subsequently, the sewage is dispersed at the small end of the cone of the diversion cover 4 and enters the upper space of the medicine spraying chamber 2 in a multi-strand state through the small round holes on the diversion cover 4. Finally, the sewage converges again at the water outlet 202 and flows into the lower-stage sewage treatment tank through the water outlet 202.
[0027] When the sewage flows through the water outlet 202, in order to further mix the sewage with the internal medicine, as Figure 1 、Figure 3 and Figure 5 As shown in the third embodiment of the present utility model Figure 5 , a mixer 7 is provided at the connection between the top opening of the spraying bin 2 and the water outlet 202.
