The invention discloses a domestic waste leachate treatment method. The method includes: (1), gridding: intercepting in a water storage tank through a mechanical grating to effectively lower suspendedmatters in water to relieve load for subsequent process treatment; (2), coagulation and precipitation: using a lifting pump to lift outgoing water through gridding to a coagulation and precipitationtank, and adding an agent for coagulation and precipitation to remove heavy metal, SS and part of organic matter pollutants; (3), UASB: using the pump to lift outgoing water from the coagulation and precipitation tank to UASB for treatment; (4), MBR process: allowing outgoing water going through UASB to enter a MBR treater for further treatment to obtain primary permeate; (5), DTRO: allowing the primary permeate to pass a disc tube type concentration membrane to obtain outgoing water. The method is simple and convenient in operation, remarkable in treatment effect, energy-saving, pollution-free, high in practicability and capable of efficiently removing organic matter and heavy metal in waste leachate to enable the waste leachate to reach an objective of zero emission.
