The invention discloses an ecological system for recycling domestic sewage of an apartment. A purified water collecting device is arranged on a lower layer of the ecological system; a sewage temporary storage device is arranged on an upper layer of the ecological system; an intermediate layer of the ecological system is a purified layer; a water supplying pressure pump is arranged on the ecological system. The ecological system disclosed by the invention has the beneficial effects of simple structure, good stress performance and simplicity and convenience in processing; collection and treatment of the domestic sewage are finished, and the cost of building equipment is reduced; water resources are saved, and are sufficiently utilized; the domestic sewage can achieve the aim of recycling, and is quickly collected in a large amount; the sewage temporary storage device can be used for quickly collecting and storing the domestic sewage by a water delivery pipe; the domestic sewage is subjected to water seepage and water purification for a period of following-up time; meanwhile, a real-time monitoring system provides scientific data information for maintaining an ecological engineering system and detecting the effectiveness; the effects of efficiently utilizing the domestic sewage, reducing the water supplying pressure and saving the water resources are realized.
