Preferably, described accessory equipment also comprises aerator, is arranged at below the water surface, and it is fixed in described buoyant means 3.Air can be passed in water by aerator 3, make water contact oxygenation with air, and owing to churning the surface, accelerate oxygen in air and shift in water, thus complete the object of oxygenation.In addition, aerator prevents aerosoles from sinking in addition, strengthens the object that organic matter contacts with dissolved oxygen with germ, thus ensures that in water, germ is under the condition having sufficient dissolved oxygen, to oxygenolysis organic in sewage.
As a kind of embodiment, as shown in Figure 1, in described floatation unit, also comprise a header box, be fixed in described buoyant means 3; After header box at least two adjacent described floatation unit is connected in series successively, be collected to a total header box; After at least two total header boxs are connected in series successively, be collected to described inverter 12.As preferred embodiment, be collected to total header box after every 16 header boxs can be selected to be connected in series successively, after every 20 total header boxs are connected in series successively, be collected to described inverter 12.
Alternatively, described floatation unit is also provided with solar-cell panel support, for fixed solar cell panel, described support is the combination of one or more in fixed angle formula or single axle or twin axle or polar mounts.
In addition, described solar panel fixed support is also provided with spray equipment, described spray equipment extracts cold water and sprays extremely described solar panel surface, or spray is to described Solar panel backside, or sprays surface and the back side of extremely described solar panel simultaneously.
Particularly, described spray equipment is as cooling dust collector, and described spray equipment extraction cold water sprays the front-end and back-end to solar panel respectively.The spray of front end is used for cleaning solar energy cell plate, and the shower nozzle at the back side is used for cools solar cell plate.
Its method to set up can be as shown in Figure 10, as can be seen from Figure 10, the bottom of spray equipment I directly extend into below the water surface, like this directly can obtain water source, water source sprays from the shower nozzle of spray equipment facing to the direction of solar panel, realizes effect of cooling dedusting.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of extending out or variation be still among the protection domain of the invention.
