1, connect the waste liquid pipeline: connect the waste liquid pipeline to be treated to the inlet port of the negative pressure waste liquid collection device, and at the same time connect the outlet port to the waste liquid storage container or the pipeline of the subsequent treatment equipment.
2, adjust the negative pressure parameters: according to the type of waste liquid and treatment needs, adjust the negative pressure parameters of the negative pressure waste liquid collection device, so that the waste liquid can flow smoothly through the device and be adsorbed and collected.
3, start the device: press the negative pressure waste liquid collection device on the start button, to confirm the normal operation of the device to start processing waste liquid.
4, shut down the device: after processing, press the stop button on the negative pressure waste liquid collection device, after the device stops running, disconnect the power supply and dismantle the waste liquid pipeline.
