Siphon type composite vertical subsurface flow constructed wetland
A siphon type composite vertical subsurface flow constructed wetland has an uplink pool with a depth ¾ that of a downlink pool. Siphon-type drain tubes are equidistantly distributed at a first outer side of the uplink pool, and a total flow of the drain tubes is slightly greater than a largest total influent flow. Three layers of substrates are paved on each pool. A substrate on a first layer is a biological ceramsite having a relatively small grain size, another substrate on a second layer is zeolite having a relatively large grain size, and a further substrate on a third layer is cobblestone having a large grain size. The third layers of the pools are integrally communicated, and sewage in the downlink pool flows to the uplink pool through a communication port. Sludge on bottom layers of the pools is discharged from a siphon tube with water.
