First water CODCrAverage value is 49.70mg/L, is reached most in the 20th to 25 period COD removal rate increment of aeration
Greatly, it tends towards stability later.When being aerated for 35 period, CODCrContent is reduced to 13.92mg/L.
2, such as Fig. 2 is built biological floating bed, on the basis of specific implementation step S6 and S7, can obtain plant or biology respectively
Film filler individually handles the effect of water body.
A, B, R respectively represent C hereinbefore1/2、C4And C0The bracketplant of culture is tamed, M represents biofilm packing, and CK is represented
It is not added with the raw water of any processing.Water quality is measured every three days, it is as a result as follows：
(1) total nitrogen (mg/L)
Since inevitably error leads to the initial total nitrogen of seven groups of processing in each group treatment conditions difference and experimental implementation
Concentration is different.A water quality is surveyed every three days, as a result as shown above.It sampled and measures at the 11st day, sought by 1/2 times of Huo Gelan
The plant of nutrient solution domestication is high compared with other groups to the adsorption cleaning ability of this experiment water body, experimental result as it can be seen that the plant of domestication and
Microorganism combination processing eutrophic water body has good effect.
(2) total phosphorus (mg/L)
The removal rate of total phosphorus is A+M>B+M>R+M>A>B>M>CK, it follows that the plant of 1/2 times of Huo Gelan nutrient solution domestication
The clean-up effect of object combination microorganism is best, can be that the microorganism to swim in water body carries since plant has flourishing root
For adhering to place, not only itself phosphorus can be absorbed, it helps microbial growth, therefore adsorption effect is good.A+M groups are gone
Except rate reaches 86%, 59% is higher by relative to control group.
(2) permanganate index (mg/L)
According to national surface water class standard, the first water water quality I of this experimentmn>10, belong to V class.After treatment, with place
The variation of time is managed, the permanganate index of each group decreases, wherein B+M groups Imn<6, reach III class.By table as it can be seen that taming and dociling
Change the ability for improving plant absorption permanganate, clean-up effect B>A>R.In addition to R+M groups, plant and microorganism junction
The with obvious effects of reason is higher than other processing groups.
(3)BOD5(mg/L)
The first BOD of raw water5For 5.92mg/L, by processing in two weeks, water quality BOD5Variation it is as shown in the table：
| R+M | A+M | B+M | A | B | M | CK |
| 4.8 | 4.4 | 3.2 | 4.4 | 3.6 | 4.8 | 5.6 |
In several groups, B+M best results, BOD5Reduce 45%.By B+M<It is mutual that B can speculate that plant root is constituted with biomembrane
Sharp cogeneration system so that the two combines the repairing effect higher than independent plant or independent microorganism.B<A<M is as it can be seen that 4 times of lattice suddenly
The absorption conversion capability highest of the bracketplant of blue nutrient solution domestication, and plant is more preferable compared with the repairing effect of biomembrane.
The present invention is exemplarily described above in association with attached drawing.Obviously, present invention specific implementation is not by above-mentioned side
The limitation of formula.As long as using the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress；Or not
It is improved, the above-mentioned design of the present invention and technical solution are directly applied into other occasions, in protection scope of the present invention
