The invention provides a domestic sewage purification and discharge system which comprises a first communication pipeline, a collection device, a second communication pipeline, an ecological pool and a collection pool, the first communication pipeline is a closed pipeline, one end of the first communication pipeline is communicated with the outlet end of a domestic sewage pipeline, and the other end of the first communication pipeline is communicated with the ecological pool. The other end of the first communicating pipeline is communicated with the inlet end of the collecting device, and vegetation is planted at the upper part of the ecological pool. According to the domestic sewage treatment device, an oxygen-free environment is provided for domestic sewage through the closed first communication pipeline, bacteria can decompose sundries in the sewage in the oxygen-free environment, odor in the domestic sewage cannot be emitted into the external environment through the closed first communication pipeline, the odor in the air is reduced, and the domestic sewage treatment device is convenient to use. The collecting device can be used for collecting impurities in the sewage and purifying the sewage, and compounds containing ammonia, nitrogen, lithium, potassium, fluorine and the like in the sewage can be used as nutrients to provide nutrients for vegetation above the ecological pool, so that a comfortable living environment is created for residents.
