Referring to fig. 1, the utility model provides a disease accuse laboratory waste water degassing unit, including collecting pit 1, disinfection pond 3 is linked together through first pipeline 2 and collecting pit 1, disinfection pond 3 is inside to be provided with UV lamp 4, ozone generator 5 is linked together through first trachea 13 and disinfection pond 3, aeration fan 6 is linked together through second trachea 14 and disinfection pond 3, be provided with pump 7 and venturi ejector 12 on the first pipeline 2, be connected with pipette 9 on the venturi ejector 12, pipette 9 inserts in liquid medicine pond 10, be provided with first valve 11 on the pipette 9.

The working principle is as follows: laboratory waste water can get into collecting pit 1 through waste water pipe 8, later gets into disinfection pond 3 through first pipeline 2, venturi ejector 12 (venturi ejector 12 can establish ties in first pipeline 2) under the drive of pump 7, when needing to add disinfection liquid medicine, opens first valve 11, and waste water presses behind pump 7 and presses and enters into the injection intracavity from the ejector entry of venturi ejector 12 and form high-speed jet fluid, and the high-speed fluid pressure drop that produces at "throat" department makes disinfection liquid medicine be inhaled into venturi ejector 12 from liquid medicine pond 10 through pipette 9 and waste water intensive mixing back gets into disinfection pond 3. The flow rate of the sterilizing liquid can be adjusted by adjusting the degree of opening and closing of the first valve 11. The wastewater enters the disinfection tank 3 and is disinfected by disinfection liquid medicine and irradiated by a UV lamp, the ozone generator 5 charges ozone into the wastewater through the first air pipe 13 for ozone disinfection, and the aeration fan 6 charges gas into the wastewater through the second air pipe 14 for aeration and stirring. After the wastewater is disinfected by the three disinfection methods, the drain valve is opened, and the treated wastewater can be discharged through the drain pipe 22.

The utility model discloses, one, utilize venturi ejector 12 to add the disinfection liquid medicine in to waste water for disinfection liquid medicine and the mixed diffusion section intensive mixing of waste water in venturi ejector 12, the flow of disinfection liquid medicine added is adjusted to the switching degree of the first valve of accessible 11 simultaneously, enters into the mixed mode of disinfection pond 3 on the limit for waste water and disinfection liquid medicine proportional mixing. Compared with the prior art, the waste water is firstly injected into the disinfection tank 3, and then the disinfection liquid medicine is added into the waste water in the first tank, so that the mixing is more uniform, and the disinfection effect is good. And secondly, the aeration fan 6 is added for aeration stirring, so that ozone, disinfection liquid medicine and wastewater can be further uniformly mixed, the dissolution rate of ozone in wastewater is increased, and a better disinfection effect is achieved. And thirdly, the disinfection is carried out by adopting a method combining three modes of UV disinfection, liquid medicine disinfection and ozone disinfection, and compared with any single disinfection mode in the prior art, the disinfection device has wider disinfection range and more thorough disinfection effect.

The venturi ejector 12 is arranged on the first pipeline 2 in parallel, and the first pipeline 2 is also provided with a second valve 20 and a third valve 21, so that when the disinfectant liquid needs to be added into the wastewater, the third valve 21 can be closed, and the second valve 20 and the first valve 11 can be opened; when the disinfectant liquid is not required to be added, the second valve 20 and the first valve 11 can be closed, the third valve 21 can be opened, and at the moment, the wastewater directly enters the disinfection tank 3 through the first pipeline 2 without passing through the venturi ejector 12, so that the flow resistance of the wastewater is small, and the energy consumption is reduced.

The outlet of the first line 2 is provided as a first spray head 17. So, waste water and disinfection liquid medicine get into disinfection pond 3 with the mode of spraying, can be more even with waste water and disinfection liquid medicine mixture.

The first valve 11 and the drain valve are set as electromagnetic valves, and the device further comprises a controller electrically connected with the first valve 11, the drain valve, the pump 7, the aeration fan 6, the ozone generator 5 and the UV lamp 4.
