Since the structures of the two or more layers of pipes are identical to the connection structure between the two-layer drain branch pipe 7 and the main drain pipe 1, the connection structure of the two or more layers of drain branch pipes and the main drain pipe 1 is omitted in fig. 1.

The embodiment comprises a main drain pipe 1 penetrating through each floor and the bottom end of which is communicated with a sewage well, and drain branch pipes arranged corresponding to each floor of a house building, wherein one end of each drain branch pipe penetrates through a floor slab of the corresponding floor to be connected with the main drain pipe 1, and the other end of each drain branch pipe is led into the corresponding floor; the sewage treatment system also comprises a standby drain pipe 2, wherein the bottom end of the standby drain pipe 2 passes through the first floor slab 8 and is communicated with the sewage well; the main drain pipe 1 and the standby drain pipe 2 are communicated through a first communicating pipe 3 and a second communicating pipe 4; the first communicating pipe 3 and the second communicating pipe 4 are sequentially arranged from bottom to top, the first communicating pipe 3 is positioned at a position which is one meter away from the first floor slab 8 and is used for communicating the main drain pipe 1 with the standby drain pipe 2, and the height of a communicating port of the first communicating pipe 3 and the main drain pipe 1 is higher than the height of a pipe orifice of the first floor drain branch pipe 6 in a room; the second communicating pipe 4 is arranged at the top end of the standby drain pipe 2 to communicate the standby drain pipe 2 with the main drain pipe 1, and the communicating port with the main drain pipe 1 is lower than the height of the two-layer drain branch pipe 7; the first layer drain branch pipe 6 is communicated with the main drain pipe 1 through a check valve 5.

The first communication pipe 3 and the second communication pipe 4 may be horizontally disposed or may be obliquely disposed, and in this embodiment, the first communication pipe 3 and the second communication pipe 4 are horizontally disposed. The number of communicating pipes may be one or two, and two are preferably provided in this embodiment.
