Narrative:
Frequency: tower. ATC facility: ord tower. Location: departure on runway 4L. At 1000 ft, we turned on wing anti-ice, heard loud bang with subsequent aircraft vibration. Aft airstair and standby hydraulic overheat lights came on. Call from flight attendant reported loud bang and noise in aft airstair area. We had a commuting air carrier pilot check area and confirmed noise but could not see any other damage. We declared emergency and requested equipment. Briefed #1 for emergency landing. Flight attendants prepared cabin for landing while we completed checklists and joined ILS runway 4R. Landed and taxied without incident. Maintenance found #1 engine pneumatic duct ruptured completely causing collateral damage in area and causing standby hydraulic lines to overheat. Entire crew performed in an exemplary fashion. They are all to be commended on their professionalism.
