Among the prior art, need send the waste liquid into the processing station and disinfect after the waste liquid in the butt joint equipment extraction waste liquid collecting device, the waste liquid after the disinfection just can discharge. Therefore, the use of the apparatus requires additional disinfection stations to be associated with the apparatus in order to accomplish the disposal and discharge of the waste liquid.
