The invention relates to an anaerobic zero-valent iron sewage treatment method, belonging to the sewage treatment technical field. The anaerobic zero-valent iron sewage treatment places zero-valent iron in an anaerobic reactor and utilizes the environmental conditions of the anaerobic isolated air to largely reduce the formation rate of the rust of zero-valent iron and avoid the formation of hardening; meanwhile, the method uses the reducing action of metal iron to increase the anaerobic reductive atmosphere, balance the pH and increase the effect of the anaerobic organism. A circulating pump is adopted for sewage backflow so as to increase the overflow load of an iron/activated carbon layer and the reaction effect of zero-valent iron, improve the fluidization effect of sludge to increase the anaerobic process efficiency. In a sewage treatment system, ferrous iron contained in the discharged sewage is oxidized to Fe(OH)3 with the air and the coagulation generated in the process can further purify the sewage. Long-term experiment research shows that the decolorizing rate of the sewage treatment method for dye wastewater can teach 85%-95%, the COD can be reduced by more than 50% and the biodegradability can be increased to more than 0.3.
