Plant is the important component of artificial swamp.In Constructed Wetland for Wastewater Treatment, the effect of plant can return Receive as 3 important aspects:1. recycle sewage in using state nutriment, absorption, enriching heavy metal and some have Malicious harmful substance；②Wei Gen areas aerobic microbiological conveying oxygen；3. enhancing and the waterpower transmission for maintaining medium.
Wetland plant is selected it is noted that principle：1. detergent power, durability against pollution and cold-resistant, heat resistance are strong, to different Pollutant uses corresponding floristics；2. select in the good plant of local adaptability, preferably eciophyte；3. root system is sent out Reach, biomass it is big；4. diseases and insect pests resistance is strong；5. it is preferably formed with extensive use or economic value；6. manageability, comprehensive utilization value It is high.
Different vegetation types has certain specific aim to different polluters.It is preferably wet to nitrogen phosphorus ligands effect Ground plant, such as wild rice stem, reed, raupo, rush.The plant that heavy metal has preferable removal effect is：Common cattail, and it is right The heavy metals such as Pb, Zn, Cd have preferable removal to act on.
Oxygen caused by photosynthesis can be delivered to root area by Plants of Constructed Wetlands by air flue, in going back for plant roots area The microenvironment of oxidation state is formed in ortho states medium.The aerobic region in this area and anoxic zones exist for the good of root area jointly Oxygen, facultative and anaerobe provide each suitable microhabitat, different microorganisms is had a role to play, performance is complemented each other Effect.Because plant roots and root system are to the penetration of medium, many small air chambers or gap are formd in media as well, The closure of medium is reduced, enhances the gas porosity of medium, so that the waterpower transmission of medium is strengthened and maintained.
The factor for influenceing plant treatment effect has seasonal decline, such as different groups of coup injury, scratch, water quality and matrix The decline of water plant can be caused into, the height of water level and eutrophic state.
Microorganism is purification sewage " main force " in artificial swamp.Its quantity can reflect artificial swamp to a certain extent Purify the ability of sewage.They are translated into nutriment and energy using organic matter as the abundant energy.Artificial swamp exists Before handling sewage, the quantity and natural wetland of each quasi-microorganism are essentially identical.But as sewage constantly enters artificial swamp system System, the quantity of certain micro-organisms will gradually increase, and reach maximum within a certain period of time and tend towards stability.
Microorganism in artificial wet land system mainly removes organic matter and N in sewage, the organic substance of some difficult degradations The Induced variation characteristic with microorganism is needed with noxious material, domestication suitable absorbent is cultivated and digests these organic substances and have The predominant bacteria of noxious material, is degraded.The activity of microorganism is the main factor of wetland purification sewage in artificial swamp.It is existing There is research to have been found that microorganism has all played important function during BOD5, COD and nitrogen etc. degrade.
Dominant bacteria in artificial swamp have pseudomonas Pseudomonas, alcaligenes Alcaligens and Flavobacterium Flavobacterium, is the microorganism of fast growing, and it contains degradative plasmid in vivo, is decomposing organic matter Main body microbial population.In addition, the organic matter and Toxic for some difficult degradations must use microorganism induction variation property, training Educate domestication suitable absorbent and digest the sociales of these materials, degraded.
Meanwhile research finds that microbe number in wetland and species and wastewater purifying efficiency also have certain relation.Its Quantity more at most clearance is higher.BOD5 clearance and wetland total number of bacteria are significantly correlated wherein in sewage, the removal of ammonia nitrogen Rate and the quantity of nitrobacteria and denitrifying bacteria are closely related, the clearance of total Escherichia coli and wetland protozoan in sewage There is also significant correlation with Population of Actinomycetes.This is also served from one side explanation wetland microorganism in contaminant degradation Important function.
Matrix, also known as filler, it is being paved into by different size of gravel, sand, soil particle etc. by certain thickness of artificially designing For plant growth, the bed body of microorganism attachment.Matrix is the main place of sewage disposal, and the main carriers of microorganism, together 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.
