High-sulfur wastewater resourceful treatment method and system

The invention discloses a high-sulfur wastewater resourceful treatment method and system, the system comprises an escape reaction kettle, a protective gas buffer tank, a vacuum pump, an absorption reaction kettle and a gas circulating pump which are circularly connected, and the escape reaction kettle and the wastewater circulating pump form a wastewater self-circulation system; the escape reaction kettle, the absorption reaction kettle and the gas circulating pump form a gas circulating system; and the protective gas buffer tank, the escape reaction kettle, the absorption reaction kettle and the vacuum pump form a protective gas circulating system. According to the high-sulfur wastewater resourceful treatment method and the high-sulfur wastewater resourceful treatment system, recycling of valuable resource sulfur in the high-sulfur wastewater is achieved, the recycling rate reaches up to 95%, the ORP value is adopted as the basis of end point judgment, and automatic control of the system can be achieved. 本发明
