Through such a setting, the pressure detector 13 and the flow regulating valve 15 are interlocked and controlled. When the pressure of the waste liquid storage tank 1 is lower than a certain value, nitrogen is introduced into the waste liquid storage tank 1 through the first nitrogen pipeline 10 and the second nitrogen pipeline 11, and the nitrogen flow is controlled by the flow regulating valve 15, so that the pressure in the waste liquid storage tank 1 is at a slightly positive pressure, and the waste gas generated in the waste liquid storage tank 1 is sent to the subsequent waste gas incineration device.

[0025] The organic waste liquid in the pipeline is sent to the waste liquid storage tank 1 through the collection bucket 2. When the remote level meter 12 detects that the liquid level of the organic waste liquid in the tank reaches a certain height, the interlock is triggered, and the diaphragm delivery pump 4 starts to start. After the waste liquid in the waste liquid storage tank 1 is filtered by the filter 3, it is sent to the subsequent waste liquid centralized treatment device by the diaphragm delivery pump 4 through the third treatment pipeline 8. Nitrogen is introduced into the waste liquid storage tank 1 through the first nitrogen pipeline 10 and the second nitrogen pipeline 11, so that the pressure in the waste liquid storage tank 1 is at a slightly positive pressure, and the waste gas generated in the waste liquid storage tank 1 is sent to the subsequent waste gas incineration device through the single call valve 16.
