[0006] In one possible embodiment, the filler includes a stone layer and at least one quartz sand layer; the stone layer is filled on the inner bottom of the tank body, and the quartz sand layer is filled in the tank body above the stone layer; by adopting this structure, after the probiotics from the probiotic fermentation device enter the tank body through the connecting pipe, and after the domestic wastewater and the oxygen-enriched micro-nano bubble water enter the tank body, since the oxygen-enriched micro-nano bubble water contains a large amount of oxygen atoms, the probiotics can multiply in the quartz sand layer and the stone layer (the probiotics can multiply in the gaps in the quartz sand layer and the gaps in the stone layer), thereby enabling the probiotics to decompose the nitrogen and phosphorus elements in the domestic wastewater, so as to achieve the purpose of domestic wastewater treatment.

[0007] In one possible embodiment, three layers of quartz sand are provided, and the three layers of quartz sand are stacked and filled in a tank body located above the stone layer; by adopting this structure, through the arrangement of multiple layers of quartz sand layers, probiotics can have more reproduction space (probiotics can reproduce in large numbers in the gaps of the quartz sand layers), so that the probiotics can further reproduce in large numbers, thereby improving the efficiency and effect of probiotics in decomposing nitrogen and phosphorus elements in domestic wastewater.

[0008] In a possible embodiment, the integrated intelligent machine for nitrogen and phosphorus removal also includes a backwash pipe and a second water pump; one end of the backwash pipe is connected to one side of the bottom of the tank body, the other end of the backwash pipe is connected to the second water inlet end of the solenoid valve, the second water pump is installed on the backwash pipe, and the second water pump is electrically connected to the controller; by adopting this structure, when the first water pump stops working, the oxygen-enriched micro-nano bubble water generator stops working, the valve is closed, the second water pump works, and when the controller controls the solenoid valve to connect the backwash pipe with the pipeline, the backwash pipe can extract water at the bottom of the tank body and re-transport the water to the interior of the upper end of the tank body through the backwash pipe, the solenoid valve and the pipeline, thereby realizing backwashing of the tank body.

[0010] In a possible implementation, a blade is provided on one side of each cutting strip, and the blades on all the cutting strips are oriented in the same direction. By adopting this structure, when the cutting strip rotates, the mixed water of domestic sewage and micro-nano oxygen-enriched bubble water entering the tank body can collide with the blade of the cutting strip, so that the cutting strip can further reliably cut and break up the mixed water of domestic sewage and micro-nano oxygen-enriched bubble water, and further fully mix the domestic sewage and the micro-nano oxygen-enriched bubble water. After the domestic sewage and the micro-nano oxygen-enriched bubble water are fully mixed and fall into the filler, the decomposition efficiency and effect of the probiotics that multiply in large quantities in the filler on the nitrogen and phosphorus elements in the domestic wastewater can be further promoted.
