Abstract: A high-load organic wastewater dark fermentation biohydrogen production device and a hydrogen production method are provided. An exhaust port of the production device is communicated with a gas collection region through a gas pipe; a return inlet is arranged at a bottom; a baffle plate is arranged in a two-phase separation device; the baffle plate has a helical shape that makes influent water form a helical centripetal water flow path; one end of an inert gas communicating pipe is connected with an air hole at a bottom of the gas collection region; the other end of the inert gas communicating pipe is communicated with an air intake disc; the inert gas communicating pipe is provided with a connecting hole and an air pump; and the gas collection region is connected with a gas buffer tank and a hydrogen storage tank in sequence. A two-phase separation unit is also provided.
