Normally, on a true backwash your water is NOT returned to the pool but rather exits to the drain.  Sounds to me like your backwash exit is badly connected or else the drain valve is closed and by way of pressure relief, the backwash water is exiting to the pool.

Is your drain valve open?  It should only be shut for the short period during which you open your pre-filter and it should remain open for all other regular cleaning operations.
