Embodiment Construction

[0026] figure 1 A preferred embodiment according to the invention is shown with arrows indicating the direction of water flow. figure 2 yes figure 1 The schematic diagram of the side structure of the multi-media layer waveform subsurface flow constructed wetland is shown. In this embodiment, the multi-media layer waveform subsurface flow constructed wetland includes a soil layer 5 , a filler layer 10 , a baffle 3 , a water inlet device 1 , a water outlet device 7 , a water distribution tank 11 and plants 4 growing on the soil layer 5 . The filler layer 10 is arranged under the soil layer 5 and is divided into an upper layer 6 , a middle layer 8 and a lower layer 9 from top to bottom. The upper layer 6 is filled with gravel with a particle size of 5-10 mm. The middle layer 8 is filled with gravel with a particle size of 15-25 mm and a composite packing bag 2 . The lower layer 9 is filled with gravel with a particle size of 30-50mm. Composite filler packages 2 are interlac...

Abstract

The invention discloses a wavy subsurface flow constructed wetland with a multi-medium layer. The wavy subsurface flow constructed wetland comprises a packing layer, more than two baffle plates, a soil layer and plants, and the baffle plates are arranged in the packing layer in a staggered manner, so that water flow forms vertically fluctuated subsurface flow when flowing through the packing layer. Packing of the packing layer comprises gravel and a composite packing bag, and packing of the composite packing bag comprises soil, wood shavings, charcoal and scrap iron. By layered filling of the composite packing, the water flow regime of the wetland is changed by the baffle plates to form the vertically fluctuated subsurface flow, nitrogen and phosphorus removal effects of the wetland can be enhanced, and the wetland has a good application prospect.

Description

technical field [0001] The invention relates to a constructed wetland, in particular to a waveform subsurface flow constructed wetland with multi-media layers. Background technique [0002] Constructed wetland refers to artificially built pools or trenches, laying an anti-seepage water-proof layer on the bottom, filling a certain depth of matrix layer, planting aquatic plants, and utilizing the physical, chemical, and biological synergies of matrix, plants, and microorganisms to make sewage get better. purify. According to the way of sewage flow, it is divided into surface flow constructed wetlands, horizontal subsurface flow constructed wetlands and vertical subsurface flow constructed wetlands. Because of the coordination with the surrounding environment, the artificial wetland has the advantages of low investment, convenient operation and maintenance, good treatment effect and strong impact load resistance. It is used in the treatment of urban domestic sewage, agricultur...
