In the waste disposal plant of aforesaid composite under-current artificial wetland, described waterplant is Canna generalis Bailey, calamus, umbrella grass, Arundo donax, reed, power flower, Herba Eichhorniae etc. again.
Compared with prior art, the utility model is formed compound wetland unit by horizontal drowned flow artificial wet land, vertical subsurface flow wetland and surface current artificial wetland are organically combined.This compound wetland unit has the advantages that floor space is few, investment is low.The utlity model has good purification, structure, more simply, not to be prone to obstruction, processing power and treatment effect better, and characteristics easy to maintenance, that hydraulic load is higher and soil removability is stronger.
Use the utility model to compare, have following characteristics with traditional sewage disposal:
1, the water quality after the treat effluent is better than the water quality after traditional biological is handled;
2, the environmental landscape effect is better, and the sewage works free from extraneous odour does not grow mosquitos and flies;
3, select the various plants collocation for use, ensureing has good treatment effect under the Various Seasonal weather condition;
4, select perennial emergent for use, avoid causing filler to stop up after the plant death;
5, the undercurrent type adapts to the weather condition of extremely frigid zones especially, gauging line below the filler face, winter the freezing plant that can not freeze to death;
6, unpowered facility, managerial personnel only need periodic cleaning grating tank and winter that the plant ground segment is sliced off to get final product essentially no working cost;
7, can plant the waterplant of certain economic value, solve sewage disposal working cost problem.
