Example 2:

On the basis of and different from Embodiment 1, the present invention provides another technical solution of the aeration plate 41: the aeration plate 41 is arranged in an inclined manner, and the inclination direction is the same as the spiral blade 3.

Such an arrangement will cause the vortex generated by the water flow driven by the aeration plate 41 to impact with the vortex generated by the spiral blade 3 when rotating, but the impact will be reduced, making it easier for the downward vortex generated by the spiral blade 3 to be buffered by the buffer plate. 51 neutralizes the water flow vortex at the bottom of the settling chamber 11. This setting will make the sediment at the bottom of the settling chamber 11 tend to settle naturally.

Example 3:

On the basis of Embodiment 1 and different from Embodiment 3, the present invention provides another technical solution of the aeration plate 41: the aeration plate 41 is arranged in an inclined manner, and the inclination direction is opposite to the spiral blade 3.

Such an arrangement will cause the vortex generated by the water flow driven by the aeration plate 41 to impact with the vortex generated by the spiral blade 3 when the aeration plate 41 rotates. However, the impact will increase and the downward vortex generated by the spiral blade 3 will not be easily absorbed by the buffer plate. 51 neutralization, which greatly increases the vortex of the water flow at the bottom of the settling bin 11. This setting will increase the reaction time between carbon dioxide gas and boiler gray water, further improving the treatment efficiency of the boiler gray water. However, the sediment at the bottom of the settling bin 11 will increase with the The vortex of the water flow produces centrifugal force and the bottom settles unevenly, which affects subsequent recycling.
