The novel micro-nano ozone disinfection gravity type fine filter according to claim 5, wherein the back flushing device comprises a siphon ascending pipe (9), a siphon connecting pipe and a siphon descending pipe (14) which are sequentially communicated, the siphon ascending pipe (9) is vertically arranged, one end of the siphon ascending pipe is communicated with the fine filtering water inlet, the siphon descending pipe (14) is vertically arranged, one end of the siphon descending pipe is communicated with the drainage system, and the siphon connecting pipe is obliquely arranged.
7. The novel micro-nano ozone disinfection gravity type fine filter according to claim 6, wherein a siphon auxiliary pipe (11) extending vertically downwards is communicated with the middle position of the siphon connecting pipe, an exhaust pipe (12) extending obliquely downwards is communicated with the top position of the siphon connecting pipe connected with the siphon descending pipe (14), and the siphon auxiliary pipe (11) and the exhaust pipe (12) are intersected to form a Y-shaped pipe;
the water ejector is arranged at the junction of the siphon auxiliary pipe (11) and the exhaust pipe (12) and is used for sucking air at the upper ends of the exhaust pipe (12) and the siphon descending pipe (14) away so that the siphon descending pipe (14) forms negative pressure.
8. The novel micro-nano ozone disinfection gravity type fine filter according to claim 7, wherein a back flushing timing pipe (13) is further communicated with the top position of the connection of the siphon connecting pipe and the siphon descending pipe (14), and when the water level drops below the lower pipe orifice of the back flushing timing pipe (13), the siphon of the back flushing device is destroyed, and back flushing is finished.
9. The novel micro-nano ozone disinfection gravity type fine filter according to claim 8, further comprising a forced back flushing pipe (10) connected to the upper end of the water jet at the joint of the siphon auxiliary pipe (11) and the air extraction pipe (12), wherein a valve is arranged on the forced back flushing pipe (10).
