Rain sewage purification system for terrace wetland
The invention discloses a terrace wetland rain sewage purification system which comprises a first step constructed wetland, a second step constructed wetland and a third step constructed wetland, the first step constructed wetland is composed of a vertical subsurface flow constructed wetland, a horizontal subsurface flow constructed wetland and an adjusting tank, a perforated water distribution pipe is adopted in the vertical subsurface flow constructed wetland, the horizontal subsurface flow constructed wetland is arranged from right to left and from large to small according to matrix porosity, and uniform water distribution in the subsurface flow constructed wetland is guaranteed; the second-step constructed wetland comprises a surface flow constructed wetland, and a water drop steel plate groove is formed in one side, bordering the subsurface flow constructed wetland, of the surface flow constructed wetland, so that water is uniformly distributed in the surface flow constructed wetland; wetland aquatic plants such as hornwort, myriophyllum verticillatum and water hyacinth can be arranged in the adjusting tank; wetland plants such as typha orientalis, cyperus alternifolius, acorus calamus, scirpus tabernaemontani and bamboo reed can be arranged in the subsurface wetland; wetland plants such as zizania aquatica, lythrum salicaria, thalia dealbata, iris wilsonii and bamboo reed can be arranged in the surface flow wetland. The third step constructed wetland is communicated with the second step constructed wetland; the device has the advantages of being stable in structure, simple in design and good in purification and ecological landscape effect, can be applied to park green land, and has the main function of purifying rainwater and domestic sewage.
本发明公开一种梯田湿地雨污净化系统，包括第一梯级人工湿地、第二梯级人工湿地、第三梯级人工湿地；所述第一梯级人工湿地由垂直潜流人工湿地、水平潜流人工湿地、调节池组成，垂直潜流人工湿地内部采用穿孔布水管，水平潜流人工湿地内根据基质孔隙度从右至左由大到小进行排列，保证潜流人工湿地内均匀布水；所述第二梯级人工湿地包括表流人工湿地，在表流人工湿地与潜流人工湿地接壤的一侧设置跌水钢板槽，使得表流人工湿地内布水均匀；所述调节池内可配置金鱼藻、狐尾藻、水葫芦等湿地水生植物；潜流湿地内可配置香蒲、旱伞草、菖蒲、水葱、芦竹等湿地植物；表流湿地内可配置茭草、千屈菜、再力花、黄花鸢尾、芦竹等湿地植物。所述第三梯级人工湿地同第二梯级人工湿地；本发明具有结构稳定、设计精简、净化、生态景观效果好的特点，可应用于公园绿地中，主要功能为净化雨水及生活污水。
