Furthermore, the filler layer is formed by stacking a plurality of net-wrapped bagged nano honeycomb sintered bodies, and microorganisms are attached to the nano honeycomb sintered bodies. The nano honeycomb sintered body is a stable inorganic material, can retain moisture, provides a good environment for the growth of microorganisms, and increases the contact between air and sewage and the microorganisms. And the nano honeycomb sintered body is packaged by a mesh bag, so that the water outlet pipe is prevented from being blocked by the nano honeycomb sintered body.

The utility model has the beneficial effects that:

1. the utility model adopts a natural ventilation structure, forms an air channel in the purification tank, provides an aerobic environment for the growth of microorganisms, and can realize sewage purification without external power.

2. When the floating rod rises to the warning line, the blockage at the water outlet of the purification tank can be observed in time, and the overflow hole is lower than the water outlet pipe, so that the phenomenon that the floating rod fails because sludge at the bottom of the tank body enters the circulating pipe can be avoided.

3. The nano honeycomb sintered body is a stable inorganic material, can retain moisture, provides a good environment for the growth of microorganisms, and increases the contact between air and sewage and the microorganisms. And the nano honeycomb sintered body is packaged by a mesh bag, so that the water outlet pipe is prevented from being blocked by the nano honeycomb sintered body.
