The horizontal recoil plate 110 is used to connect two inclined baffles 111 and provide a mounting location for the guide recoil pipe 112 and one of the location areas for secondary recoil.

And the primary hedging mixing and the secondary hedging mixing of the sewage and the medicament only need the supply of the initial pumping power of the pump body and the action of self gravity, the dependence on the power is lower, and the energy is saved.

The guiding counter flushing pipe 112 comprises a relay connecting pipe 114 arranged on the horizontal counter flushing plate 110 and two shunting counter flushing pipes 115 symmetrically arranged on two sides of the relay connecting pipe 114, a plurality of shunting pipelines 116 used for thinning and shunting the mixed liquid in the spiral reaction pipeline 106 into a plurality of strands are symmetrically arranged in the relay connecting pipe 114, a counter flushing flow guide pipeline 117 communicated with the corresponding shunting pipeline 116 is arranged in each shunting counter flushing pipe 115, and the mixed liquid is secondarily shunted to the corresponding counter flushing flow guide pipeline 117 through the shunting pipeline 116 to be subjected to counter flushing mixing in the horizontal direction.

When the mixed liquid is guided into the wash pipe 112, the mixed liquid first enters the intermediate connection pipe 114, and the mixed liquid entering the intermediate connection pipe 114 is branched again by the branch line 116 to form a plurality of mixed liquids.

The plurality of mixed liquids flow into the opposite diversion pipe 115 through the opposite diversion pipe 117 correspondingly communicated with the diversion pipe 116, and descend along the inclined plane diversion plate 111 through the opposite diversion pipe 117 again, so as to promote the kinetic energy of the mixed liquids again.

After the mixed liquid is branched into a plurality of streams via the branch line 116, the plurality of streams of mixed liquid flow through the intermediate segment 118 and the opposed segment 119 for opposed flushing.

Since the mixed liquid moves from the branch line 116 to the intermediate segment 118, the moving direction of the mixed liquid is changed by the collision with the inner wall of the intermediate connection pipe 114, and the kinetic energy of the mixed liquid is lost during the collision.

The middle section 118 is communicated with the corresponding shunt pipeline 116 and is obliquely arranged on the inclined plane guide plate 111, so that the loss of kinetic energy caused by the change of the speed direction when the shunt pipeline 116 shunts to the middle section 118 can be reduced, and the loss of kinetic energy from the middle section 118 to the opposite impact section 119 is also reduced.

The spacing between the two diverging washpipes 115 increases linearly along the surface of the inclined baffle 111, and the spacing between the tops of the two diverging washpipes 115 is minimal.

Since the offset sections 119 of the split-flow offset pipes 115 are arranged in parallel along the surface of the inclined guide plate 111, the kinetic energy of the mixed liquid in different offset sections 119 is different.

Therefore, after the mixed liquid is flushed out of the opposed sections 119, the mixed liquid flushed out of the lowermost opposed section 119 has higher kinetic energy, and the mixed liquid flushed out of the uppermost opposed section 119 has lower kinetic energy.

The distance between the uppermost counter-flushing segments 119 should be as small as possible so that the sewage and the chemicals are mixed uniformly and completely in the counter-flushing mixing between the two mixed liquids.

The receiving pipeline 120 receives the mixed liquid obtained by two shunt counter flushing pipes 115 after counter flushing and mixing, and guides the mixed liquid into the spiral buffer pipeline 121 through the action of gravity, and guides the mixed liquid into the circular reaction tank 1212 through the spiral buffer pipeline 121 for phosphorus removal reaction after secondary mixing.

The spiral buffer pipeline 121 prolongs the movement path of the mixed liquid by using the spiral characteristic of the spiral buffer pipeline, so that the movement time of the mixed liquid before entering the circular reaction box 122 is longer, and the phenomenon that the circular reaction box 122 instantly enters more mixed liquid and lacks sufficient reaction time is avoided.

Secondly, the speed direction of the mixed liquid when entering the circular reaction tank 122 is tangent to the side wall of the circular reaction tank 122, the mixed liquid in the circular reaction tank 122 is driven to rotate by the kinetic energy of the mixed liquid, and a mixing effect exists in the circular reaction tank 122.
