This invention provides a waste liquid collection and temporary storage system and method under raised floors, including a main collection tank, a backup tank, a pneumatic diaphragm pump, a waste liquid inlet pipe, a waste liquid outlet pipe, a gas phase balance pipe, a connecting pipe, an exhaust pipe, and a liquid level detection device. The main collection tank and the backup tank are located below the raised floor, and the pneumatic diaphragm pump is located above the raised floor. The main collection tank and the backup tank are connected by the gas phase balance pipe and the connecting pipe, respectively. Waste liquid enters the main collection tank through the inlet pipe. The liquid level detection device monitors the liquid level and triggers the pneumatic diaphragm pump to deliver waste liquid. In case of abnormal inflow, the connecting valve is opened to expand the capacity of both tanks, forming a temporary storage space. The system is also equipped with a multi-stage liquid level detection device, a pneumatic ball valve, and an independent control box, possessing automatic control, pressure balancing, and overflow prevention functions. It has a compact structure, is safe and reliable, and can effectively improve the continuous operation capability and emergency buffering capability of the waste liquid collection system under raised floors.
