Embodiment
1-4 is explained in more detail to the technical scheme of the preferred embodiment of the present invention, illustrated below in conjunction with the accompanying drawings.
As illustrated, this imported pollution lake body ecological purification system, its preposition structure is to include upper gate 1, is intercepted
Grid 2, plant buffering area 3 and downflow weir 4, wherein downflow weir 4 are formed by metaling, concrete masonry units, are intercepted grid 2 and are selected grid
Interspace is 10~40mm middle grid, and plant buffering area 3 can plant one or more emergent aquactic plants 9, such as reed, beauty
Any of several broadleaf plants, cattail and iris etc., its role is to absorb the nutrients such as N, P in grid drainage, and further precipitate, retain more tiny
Suspended pollutant, purify with drainage pipeline networks input lake body pollutant.
In the technical program, the bed mud that lake body also includes being arranged on lakebed improves layer and fish culture layer；The bed mud
Improve spiral shell, freshwater mussel and the one or more of shrimp that layer includes being planted in the body mud earth of lake；The fish culture layer includes silver carp, flathead
At least five kinds in fish, mandarin fish, perch, grass carp, crucian and catfish.Bed mud can be set to improve layer in lakebed in addition and carry out lakebed
The improvement of soil, mud improves spiral shell, freshwater mussel and the one or more of shrimp that layer includes being planted in the body mud earth of lake.
As a kind of preferred breeding way, silver carp, bighead, mandarin fish, perch, grass carp, the cultivation density of crucian and catfish
Carried out according to 20 tails/mu, 2 tails/mu, 4 tails/mu, 7 tails/mu, 15 tails/mu, 8 tails/mu；Spiral shell, freshwater mussel and the cultivation density of shrimp difference
For 3kg/ mus, 5kg/ mus and 0.8kg/ mus.The mode of above-mentioned cultivation, its fingerling Comprehensive survival probability is up to 98%, and the ecosystem can
Maintain 8-10.
In more detail, the architectural feature of above-mentioned downflow weir 4 is that be located at the perforate of main body middle and lower part delays provided with insertion plant
The pipeline of area 3 and lake body is rushed, pipeline works as low water in the external submersible sewage pump in the side of plant buffering area 3, its model 50QW42-9-2.2
When phase water level is less than the height of downflow weir 4, submersible sewage pump is opened in good time and carries out continuing purge.
Lake body is divided into eight regions by the lake surface of this lake body using series connection buoyant spheres, indicate successively A areas, B areas, C areas, D areas,
E areas, F areas 10, G areas and H areas etc., carry out lake body subregion and administer, and alternate rationally provided with surface aerator 5 in each region
With biological floating bed 6, it forms multi-stage ecological purification system on the body current direction of lake.
The above-mentioned main function of surface aerator 5 is solubilized oxygen, drop CODCr, promotes water body alternate cycles and pollution
Thing degraded is removed；Biological floating bed 6 is main by water plant layer 61, lower extension fiberfill layer 62 and ecological matrix 63 3 part structure of layer
Into water plant layer 61 is by rich nutritive material in its flourishing Root Absorption water body, while providing the life of micropopulation well
Long breeding environment, strengthens the self-purification capacity of water body；Bacterium, fungi, algae and the protozoan of the attachment of ecological matrix layer 63 etc. are micro-
Eutrophy composition in biological adsorbable water body, makes water quality gradually be improved；The lower extension fiberfill layer 62 can high intensity
Ground by suspended particulate substance in water body and remaining impurity absorption on surface, can be under biological floating bed bottom when absorption reaches saturation
Unload replacing.
Preferably, lake body bottom select submerged plant 9, based on evergreen dwarf forms eel grass, and moderately increase plant watermifoil and
Bog pondweed is so that species collocation is balanced.In sewage treatment area, using contact oxidation technology, microorganism can be carried out on filler surface
Biofilm, fast degradation purpose is reached to increase to contact with the surface of sewage.Based on this thought, the root on main lake body downstream passage
Some groups of filler purifying boxs 8 are placed according to exit width, the hexahedron filler 81 with larger surface area are charged with, when going out
Water flows through filler by purifying box eyelet 83 for a long time, and the biology formed by micropopulation is easily grown in filler surface attachment
Film, and the pollutants such as NH3-N, CODCr, TP in water body are further removed, to meet water outlet requirement.
The imported pollution lake body ecological purification system so built, can not only effectively be realized to external source import lake body
Pollutant carries out cutting dirty and purification, forms multi-level, multiunit cleaning system, and investment and operating cost are low, its cloth
Putting effect has certain ornamental value, meets the actual conditions of municipal lake ecological management.
After the pollution lake body ecological purification system and method for the present invention, body every water quality index in lake after running three months
It is obviously improved, the pollutant of external source import to lake body is retained in upstream and subsequently purified step by step, free from extraneous odour, nothing on water body sense organ
It is heterochromatic and without greasy dirt, achieve certain effect.Engineering technology and ecological restoration function are coupled by the present invention, are directed to comprehensively
Lake body water quality is purified, recovers urban lake body ecological functions and landscape effect.
Its every physical and chemical index is finally reached《Water environment quality standard》The limit value of IV class water quality, it is as shown in the table：
Described above is only the preferred embodiments of the present invention, and the improper restriction to interest field of the present invention is not constituted.It is all
Within the spirit and principles in the present invention, any modification, equivalent substitution and improvements made etc., should be included in the guarantor of the present invention
Within the scope of shield.
