The invention relates to a piece of novel household sewage treatment equipment which is characterized by comprising a water inlet valve 1, a separation net 2, a clapboard 3, a blowoff valve 4, an exhaust valve 5, a filter layer 6, an air pump 7, a hollow fiber ultrafiltration membrane component 8, a membrane bioreactor 9, an air guide pipe 10, a water guide pipe 11, a water pump 12, a water level gauge 13, a water storage tank shell 14, an ultraviolet disinfection lamp 15, a water outlet valve 16, a sponge layer 17, a modified coal cinder layer 18, a quartz sand layer 19 and an active carbon layer 20. The household sewage treatment equipment uses the membrane bioreactor to treat sewage, pollutants are degraded in the membrane bioreactor to remove most of CODCr, BOD5, turbidity, NH3-N, total phosphorus and the like after passing through a filter (I) and a membrane bioreaction tank (II), and then the sewage is disinfected by the ultraviolet disinfection lamp so as to be stored in a recycled water reuse tank (III) to be used as household reuse water.
