description The invention discloses a method for treating pyridine-containing wastewater by utilizing microorganisms. The method comprises the following steps: step 1, modified zeolite for specific adsorption is prepared; step 2, microorganisms capable of degrading pyridine are inoculated, the microorganisms grow with the modified zeolite as a carrier, the pyridine wastewater is introduced, aeration is conducted at the same time, and after the pyridine wastewater is subjected to aeration biological treatment, effluent enters a next-stage treatment unit; and step 3, the wastewater treated by the biological aeration method enters a nanofiltration concentration device, the treated effluent can directly enter a two-stage biochemical treatment system, and the wastewater can be discharged after reaching the standard through anaerobic and aerobic alternate treatment. The method can be used for effectively removing refractory substances such as pyridine in the wastewater, so that the sewage reaches the standard and is discharged
