Above-mentioned high-efficient constructed wetland waste water resourceful treatment device, the filter comprises the casing, locates the filter screen in the casing, filters the large granule impurity through the filter screen.

According to the efficient artificial wetland wastewater recycling treatment device, the front end of the water suction pipe is closed, and the pipeline is uniformly provided with water suction holes.

The utility model has the advantages that:

1. when the wetland is repaired periodically, water in the wetland is pumped outwards through the water lifting pump, the water lifting pipeline and the water suction pipe and then is sent to the water distribution pipe of the wet ground distribution area through the circulating pipeline, and in the process, when the water is pumped, the gap at the upper part of the wetland is filled with air, so that the aim of oxygen supplementation is fulfilled.

2. When water is extracted, the liquid level in the wetland descends, the pressure on the upper part of the wetland is reduced, and the microbial inoculum is favorably supplemented to the wetland.

To sum up, the utility model provides a restoration problem that current constructed wetland exists, it is effectual to reoxygenate, with low costs, convenient operation is strengthened to the microbial inoculum, and repair effect is good.
