The implementation principle of the highway sewage treatment structure and the treatment method thereof in the embodiment of the application is as follows: in rainy days, initial rainwater flows to the road sewage treatment structure from the road surface of the road, the initial rainwater firstly flows to the open drainage ditch 21 on the second road edge 2 through the flow guide block 4 on the first road edge 1, when the initial rainwater flows into the open drainage ditch 21, sundries and the like on the initial rainwater are intercepted through the intercepting net 5, then the initial rainwater in the open drainage ditch 21 flows into the planting cavity 31 through the first drainage pipe 61 and is absorbed by soil and plants in the planting cavity 31, on one hand, the soil and the plants can purify the initial rainwater, on the other hand, the initial rainwater can be recycled, the initial rainwater in the planting cavity 31 finally flows to the blind drainage ditch 11 from the second drainage pipe 62 and is drained away from the blind drainage ditch 11, when the rainwater continuously enters the open drainage ditch 21 from the road surface, the water level in the open drainage ditch 21 gradually rises, and the pollution caused by the later rainwater is small, therefore, when the water level in the open drain ditch 21 rises to the third drain pipe 63, the later stage rainwater is directly drained into the blind drain ditch 11 from the third drain pipe 63 and is drained away from the blind drain ditch 11, and in the whole process, the initial stage rainwater is recycled and purified through the soil and the plants in the planting cavity 31, so that the highway treatment structure has the effects of easily treating the initial stage rainwater of the highway and recycling rainwater resources.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
