The waterwheel aerator for city appearance water body restoration of the ecosystem of the present invention obtains the principle of above-mentioned technique effect
It is as follows：
The enhancing of plug-flow effect：First blade 9 of the first impeller 3 of the present invention is set as three-dimensional upside-down triangle shape, and first
Arrow direction in the rotation mode such as Fig. 2 of impeller 3.When the first blade 9 enters in water, the waist of the vertical direction of the first blade 9
Side and upper bottom edge (long side) initially enter in water, and this special setting makes the first blade 9 enter resistance when in water and reduce；First
Blade 9 is constantly downward with the rotation of paddle wheel 8, is also gradually being increased by the pressure of water, and due to the upper bottom edge of the first blade 9
(long side) and the contact area of water are big, and to which the resistance of the generation of the first blade of water pair 9 is bigger, therefore the plug-flow effect generated is then got over
It is good.Sparse, the blade of relatively uniform setting circular hole is arranged in circular hole 12 close to 9 upper bottom edge of the first blade (long side), of the invention
First blade 9 accumulates bigger with water engaging surface, and the plug-flow effect of generation is also stronger.In addition, bottom (short side) portion of the first blade 9
Point it is located at water surface topside position, suffered hydraulic pressure is smaller, also small to the effect that plays of plug-flow effect, therefore the present invention is by bottom
Setting is shorter, and apparent influence will not be generated on equipment plug-flow effect.
The reinforcement of oxygenation effect：Common quadrangle blade is compared in the design of the upside-down triangle shape of first blade 9, to the water surface
Percussion bigger, the spray bigger splash so that dissolved oxygen is more advantageous to soluble in water.Close to 9 bottom of the first blade
It is provided with intensive trepanning 12 at (short side), increases contact of first blade 9 with air, effectively strengthens oxygenation effect.If
The second impeller 7 set can generate whirlpool disturbance in rotation, can the oxygen in section top water body be brought into lower water column
In, enhance the oxygen content of swallow.

The city appearance water body ecological restoring method of the present invention, is mainly used for solving that flow is unsmooth, the slow city of flow velocity
The water quality deterioration of Landscape River or the artificial Lake Water Body of enclosed type, wherein waterwheel combined system is by waterwheel aerator and water
Vehicle water purification unit forms, and main advantage has：
(1) common water body purification technology, which often extracts the water polluted, is transported to certain place, after purification
It is flow back in water body via pipeline again, quantities is big, and investment operation is costly.And the waterwheel combined system of the present invention, collection are aerated, are clear
Slag, purification greatly reduce cost, are matched with the water purification planted in water body and plant in one without establishing the facilities such as computer room, pipeline
Object, can reach good water purification and water quality keeps effect.
(2) improvement of the waterwheel aerator in the present invention to existing waterwheel aerator, while enhancing aerator
Plug-flow effect and oxygenation effect；In addition lower water column can be brought by the oxygen in section top water body by increasing the second impeller
In, meet the needs of deeper water body is to oxygen, has greatly reinforced the self-purification capacity of water body.
(3) it is active with reality to take full advantage of the plug-flow that front waterwheel aerator generates for the waterwheel water purification unit in the present invention
The existing rotation of itself, and the structure can also absorb N, P nutritive salt while the impurity such as fallen leaves, the floating material in clearing up water body,
To purifying water body, two kinds of waterwheels efficiently solve water quality of landscape water deterioration problem under mutual coordinative role.
The city appearance water body ecological restoring method based on waterwheel combined system of the present invention obtains above-mentioned technique effect
Principle is as follows：
The orientation plug-flow that waterwheel aerator generates pushes water ladle and then pushes the rotation of entire Waterwheel-type treatment facilities, water
Wooden dipper can scoop up part water portion's hollow space in the inner, and when water ladle is moved to top, the water in water ladle can be flowed into groove
In enter the water inlet pipe that is connected with groove therewith, then enter in slag removing mechanism via water inlet.
Scarfing cinder wheel shaft in slag removing mechanism constantly rotates, and can be cut into fallen leaves, the floating material etc. in the sewage of the structure
It stays in slag removing mechanism, and the water after scarfing cinder then falls into the hypothallus of lower section.Because substrate block is rotated with waterwheel, after scarfing cinder
It is entered in substrate block immediately again when water falls into underlying substrate gap, and is gradually increasing and is left in them with substrate block, at this time base
Filler in matter can adsorb N, P nutriment in water, to play the role of purifying river (lake) water.
When substrate block constantly continues to rise, the water in matrix is then slowly flowed out from substrate block through matrix gap, is fallen into
Lower section baffle.Due to the special setting mode of baffle, purified water can gradually converge to water outlet simultaneously after falling into baffle
It is discharged from water outlet, so far completes entire cycle.
Finally it should be noted that:The above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof；To the greatest extent
The present invention is described in detail with reference to preferred embodiments for pipe, those of ordinary skills in the art should understand that：Still
It can modify to the specific implementation mode of the present invention or equivalent replacement is carried out to some technical characteristics；Without departing from this hair
The spirit of bright technical solution should all cover within the scope of the technical scheme claimed by the invention.
