The invention discloses a garbage leachate treatment technique, comprising: homogenizing the water quality of garbage leachate by an adjusting tank, and then leading the garbage leachate to enter a coagulative precipitation tank; then, alkalifying and deaminizing, and lifting into a UASB+AF tank through pump; after that, removing a great deal of organic matter, and leading the effluent to enter apacked A/O tank together with the sewage processed by the original sewage plant; removing the organic matter and the ammonia nitrogen which are difficult to degrade, and then passing through a secondary sedimentation tank and entering an advanced oxidation system for deep oxidation; leading the effluent to enter a biological aerated filter, processing by a sand filtering system and then entering a membrane processing system; and finally, ensuring the water quality of the effluent to be stable and reach the standard. As the garbage leachate treatment technique adopts the technology of 'biochemistry+ physical chemistry+
