As shown in the drawing, the denitrification tank 2 is connected with a vacuum pump through a pipeline (the pipeline is positioned above the liquid level).
The top of the denitrification tank 2 is provided with the vacuumizing pump, so that the denitrification tank 2 is vacuumized at fixed time, negative pressure is formed in the denitrification tank 2, nitrogen generated in the reaction process can escape from water conveniently, and the denitrification reaction can be accelerated.
As shown in fig. 1, the inclined immersed tube 301 is a ceramic inclined immersed tube 301.
The inclined settling tank is made of clay, firstly, in order to enable the inclined settling tube 301 to have the characteristic of being porous and absorb particles as much as possible, and secondly, the weight of the whole tank body can be reduced, and the assembly is convenient.
It should be further noted that the arrows in fig. 1 and fig. 4 indicate the flow direction of the water flow.
The foregoing description is only of the preferred embodiments of the present invention, and is not intended to limit the scope of the invention, but is intended to cover all equivalent modifications, direct or indirect, as applied to other related technical fields.
