Show within 2010 " China Environmental State Bulletin " that the big water system in China seven has different degrees of pollution, pollution level is disliked year by year
Change.
With being on the rise for rivers and lakes water eutrophication problem, with denitrogenation dephosphorizing for main syllabus target phytoremediation
Technology will become the hot spot of rivers and lakes pollution control, and important work will be especially played in the improvement of city inland river pollution water body
With.
Currently, three kinds of main effective ways of water remediation: chemical method, physical method, bioanalysis.Utilize plant and microorganism
The method of reparation is the governing measure that cost is minimum, green in existing all methods.Chinampa is that a kind of utilize is arranged on the water surface
Floating body, root absorption and absorption by some plants, removes pollutant components and the phosphorus components such as nitrogen, the phosphorus in water.Physical method
It carries out water remediation and specifically includes that diversion dilution, Sediment Dredging etc..Diversion dilution, dephosphorization can put into molysite.The biology of water body is repaired
Recovering technology is the Low investment for the cleaning ambient that newly-developed gets up, and high benefit, convenient for application, development potentiality is huge emerging
Technology, it utilizes absorption of the particular organisms to pollutant in water body, conversion or explanation, reaches and slows down or finally eliminate water body dirt
Dye restores the biological control measure of water ecology function.Divide from the selection and culture application of biology main micro- including being added directly
Biotechnology, culture microbial technique and higher organism recovery technique etc..Plant can absorb pollutant by root system, can also be with
External absorbability directly through organs such as stem, leaves.The plant of common-use words water remediation have Eichhornia crassipes (i.e. water hyacinth), reed, cattail,
Alternanthera philoxeroides, Chinese celery, duckweed, iris, water chestnut etc..Compared with traditional physical chemistry recovery technique, bioremediation technology tool
Have following characteristics: (1) expense is few, the part of only existing environment project；(2) environment influences small, not will form two
Secondary pollution or the transfer for leading to pollutant；(3) pollutant concentration can be reduced to the maximum extent.
Chinampa is also referred to as floating bed, sudd, floating wetland, the entitled Artificial Floating of English
Islands.Artificial floating island technology is a water body processing technology being currently widely used, with traditional wastewater processing method phase
Than, which is a kind of ecological technique, is worked well, have it is without secondary pollution, it is cheap and the characteristics reparation such as be easily assembled to,
Last purpose to be achieved is: water level physical condition before 1. reconstruction water bodys are damaged；2. restore water body chemical condition, truncation or
Pollution sources are reduced, chemical pollutant in water is removed；3. biological species make biology including introducing the indigenous type to have disappeared again
Wide variety
The pioneer of floating island technique research is Gurney, and SvenHoeger summarises the six functions of artificial floating island: preventing embankment from invading
Erosion and protection coastline provide habitat, beautification landscape, water quality for wild animal to purification of water quality and filtering, biological antiseptic work
With.Long 92m, wide 9.5m have been built in public the built portion harbour of work sutdy of Japan in 1997, and 40 the artificial of unit composition float
Island is the method effectively to purify water.
At home, Wu Jianqiang have studied different floating bed plant growth characteristics, nitrogen phosphorus cumulative distribution, plant nitrogen phosphorus in plant
The difference of absorbability etc..The source Luo Gu has studied repairing for the body of river water near a river of canna and the floating bed processing heavily contaminated of Fu Pu
Multiple effect.Wang Lijin has studied cyperus alternifolius, Lythrum salicaria, arrowhead, iris and canna for artificial floating island, to nitrogen in water, phosphorus, has
The removal ability of machine object and planktonic algae.Zhang Huafa shows the collocation of artificial floating island plant-Eichhornia crassipes and canna to TN in water body,
The removal of TP achieves certain good effect.
Artificial floating island is divided into wet type and dry type two major classes.Plant and water it is discontiguous be dry type, contact then be wet type.It is dry
Formula artificial floating island is generally made using mixed mud, foamed styrene etc..Wet type artificial floating island be further divided into it is frameless (
Chassis need only be made, cocoanut fiber, foam etc. are generally used) and have frame (other than frameless required object, it is also necessary to wood
Material, mixed mud etc.) two kinds.In actual utilization, wet type is on the high side, and dry type is on the low side, the main reason is that, wet type can not only rise
To the effect of beautification of landscape, and good purification of water quality effect can also be played.

So that the popularization on chinampa is very restricted with application.
(2) plant that design chinampa is often selected is affected by the time, and current technology is difficult to realize for a long time
Continuous purification water body.Centre Huang Yang et al. discovery winter calamus can be dead, and rhizome can rot；Zhang Xiaohong et al. has found thaliadeabata, beauty
Plant is larger by seasonal effect on the chinampas such as people any of several broadleaf plants, cattail, and in the case of especially catching cold in winter, Plant death is next year transplanted again,
Cost is sharply increased.
(3) wind and wave resistance pressure is weak, and anti-corrosion resistance is not strong.
