It's what some people call the water trap under a tub that prevents odours from the pipes coming up. There is a similar trap under all household sinks.

You purchase a tap set for the laundry tub that has a built in trap priming nipple and then run 1/4" Polyethelyne tubing from that nipple to the trap in the floor drain.Floor drain collars with trap primer nipples are available.The tubing may be run under the poured concrete floor of the basement.Each time the water is used in the laundry tub, a trickle of water is also sent to the trap, preventing it from drying out.

You would have to build a platform for the tub to sit on. About 3 inches if you are using a floor drain. There is a trap right after the floor drain so you would not need one at the tub. If possible you could position the tub directly over the floor drain but that would eliminate the floor drain which would be a problem if the basement every flooded.
