The application discloses a circular-truss composite horizontal
subsurface flow constructed wetland system and relates to the field of
ecological engineering. The circular-truss composite horizontal
subsurface flow constructed wetland system comprises a stepped
wetland pool and a anti-blocking
assembly. The stepped
wetland pool comprises arc-shaped
wetland units, water control components and a
pipe network unit penetrating through each arc-shaped wetland unit. The anti-blocking
assembly comprises a trigger component and a dredging component fixedly connected with the
pipe network unit. The circular-truss composite horizontal
subsurface flow constructed wetland system is applied to the landscape
water treatment of a certain city riverside green land, purifies
river water and introduces the purified
river water into the site for waterscape use, so as to save
water resources, optimize the site
microclimate and enrich the site
habitat. The site spatial form has its own characteristics, mainly taking a circular theme and having rich height differences. In combination with the
spatial design scheme, the circular-truss composite horizontal subsurface flow constructed wetland with convex or concave circular ring steps is created, land is saved, the subdivided space is prolonged, the
processing flow line is lengthened, the purification efficiency is enhanced, the ornamental property of the artificial wetland is beautified, and the pipeline output smoothness is improved through the anti-blocking
assembly.
