When can be provided again for water plant supporting carrier and growth needed for nutriment, when these nutriments are flowed through by sewage
During artificial swamp, matrix is by some physics, chemistry route (such as absorption, absorption, filtering, precipitation, complex reaction and ion exchange
Deng) make a return journey except nutriments such as SS, N, P in sewage.
Free Surface streaming system is more using soil as matrix, and undercurrent then selects from vertical streaming system according to different characteristic contaminations
Different matrix is selected, and palpus consideration is cheap, is easy to the factors such as materials.
Animal is as a part essential in Constructed Wetland Ecology System, and it is in food chain and the ecology of trophic level
Played an important role in balance, and then significant contribution has been made to the stability of artificial marsh sewage treatment system.Artificial swamp
In earthworm (Drilonema) clean rubbish can be played a part of, so as to reduce spoil disposal number.Earthworm and clam worm
(Nereisdiversicolor) heavy metal has enrichment, and these animals can be speculated to the heavy metals removal in sewage
It can serve.
