A method for low-consumption co-treatment of flue gas desulfurization wastewater and ammonia-nitrogen wastewater comprises steps as follows: (1) flue gas desulfurization wastewater containing sulfateand ammonia-nitrogen wastewater are guided into a mixing tank to be mixed; (2) the pH and the temperature of mixed wastewater are adjusted in the mixing tank; (3) firstly, a biological reaction tank is inoculated with cultured activated sludge, the mixed wastewater is introduced from the mixing tank, microorganisms in the activated sludge take ammonia nitrogen as an electron donor in the biological reaction tank, sulfate is reduced to elemental sulfur, besides, ammonia nitrogen is oxidized into nitrogen, and synchronous removal of sulfur and nitrogen is realized. The problems that the water quality of the flue gas desulfurization wastewater hardly reaches the standard after treatment with conventional physical and chemical methods, the biodegradability is poor and biological treatment is difficult are solved, and co-treatment of two kinds of wastewater is realized.
