Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

Fig. 1-2 show an integrated device for treating livestock and poultry breeding wastewater by cress, which comprises a fermentation tank 2 and a cress planting tank 31; a cress planting floating bed 31 is arranged in the cress planting groove; the fermentation tank is provided with a water inlet, a water outlet and a sealing cover; the water inlet is connected with a waste water discharge port of the farm through a water inlet pipeline; a slurry pump 2 is arranged on the water inlet pipeline; the water outlet is communicated with the cress planting groove through a drainage pipeline. The cress planting grooves are arranged in series in multiple layers from top to bottom; the total layer height of the multilayer cress planting grooves is consistent with the height of the fermentation tank; the water outlet of the fermentation tank is communicated with the cress planting groove at the highest layer so as to store water in the multiple layers of cress planting grooves under the action of gravity; the adjacent cress planting grooves are communicated through a pipeline; a plurality of cress planting floating beds are arranged in each layer of cress planting groove, and an operation channel is arranged between every two adjacent cress planting floating beds. The cress planting floating bed comprises a PVC frame body and a nylon net arranged on the PVC frame body; the PVC frame body is formed by splicing PVC pipe bodies. Or the cress planting floating bed comprises a grid plastic sheet and bamboo poles arranged on the grid plastic sheet; the bamboo poles are arranged and fixed in a cross mode. The water outlet of the cress planting groove at the bottommost layer is communicated with the water inlet of the farm through a pipeline to form circulation.

As one embodiment, the fermentation tank is 8 meters deep, the diameter is not limited, and the top is sealed by a sealing cover, so that the odor can be prevented from volatilizing, and the fermentation speed can be accelerated. After the livestock and poultry housing is flushed by clean water, the culture manure sewage is lifted to a fermentation tank by a slurry pump 2, and the fermentation is carried out in a natural state without adding any leavening agent. The cress planting groove is raised to be equivalent to the height of the fermentation tank body, 4 layers are arranged, and the height of a single-layer space is 2 meters. The cress planting floating bed is made of a nylon net with meshes of 1.5-2.0 cm by taking a PVC pipe with the diameter of 3-4 cm as a frame body; or the bed body is made of a grid plastic sheet with the aperture of 2 cm and is fixed in a crossed manner by bamboo poles.
