Narrative:

At approximately 5000 ft on climb out, smelled acrid burning odor. #1 flight attendant called and reported same odor as well as a haze near the floor around the forward jump seat. We then observed a haze near the floor by the circuit breaker panel behind the captain's seat. We immediately returned to dfw. The odor and haze dissipated rapidly during the descent. Landed 2700 pounds overweight but without further incident. Callback conversation with reporter revealed the following information: reporter states that no cause for the odor was immediately found upon landing. He suspects that it may have been oil in the ducting, since the anti-ice system had been worked on just before this flight. The flight crew did not declare an emergency.
