The effect of the current that the technical program falls to causing by variation illumination intensity, the gravity that utilizes algae lamina affixad self, water naturally, thereby making the illumination that algae receives is constantly to change, thereby having imitated nature illumination makes algae reach ready-made assimilation effect, also can absorb the carbonic acid gas dissolving in water body by photosynthesis simultaneously, also can naturally drop and slough the obnoxious flavour in water body by current; Meanwhile, by algae lamina affixad, by naturally dropping all the time, keep vertical with horizontal plane, by rotating all the time the variation with changeless light source angulation and distance, simulated the irradiation of natural light; Meanwhile, by the roughness on algae lamina affixad, carry out water lift, water falls to causing again current naturally, thereby good living environment is provided to tack algae. the best effect of the inorganic salt that are absorbed.
Further, the rectangular body of described water tank 5, its length and width is respectively along X, Y-direction.
Further, described water-in 4, water outlet 1 are positioned at rotating shaft below.
Further, described lamina affixad support 6 is impeller shape.
Further, the sway brace in fixed light source 8 and water tank 5 are connected as a single entity.
Further, the addendum flank level of the tooth bar of described level.
Further, the rotating speed of reducing motor is 20 revs/min.
Sessile algae is removed a using method for the device of aquaculture water inorganic salt, and the time of the hydraulic detention time of Inlet and outlet water in water tank is about 10 minutes.
Beneficial effect of the present invention is:
1) simple in structure, cost is not high, drops into little.
2) be easy to big area in aquaculture water and arrange, easy to use.
3) removal inorganic salt efficiency is high, and cost performance is high, and economic benefit is obvious.
4) lamina affixad plays periphtic algae, and water lift for light source provides natural imitation light-struck triple role, designs ingenious during rotation.
5) integrate inorganic salt and remove, slough obnoxious flavour and oxygenation.
6) cyclic motion of algae lamina affixad is uniform and stable, and water body fluidised form is good, and illumination variation is moderate; Dissolved oxygen, inorganic salt, carbonic acid gas, assimilation effect are good.
7) the aging periphtic algae of removal that can be easy, promotes the metabolism of algae.
8) make simply, occupy little space, installing/dismounting is simple.
9) be suitable for the processing containing aquiculture sewerages such as a large amount of harmful inorganic salt, the processing power of nitrate is greater than other biological treatment unit simultaneously.
10) due to the removal nitrate successful of this device, also can be used for hinterland sea farming system and process, thereby reduce seawater discharge, reach zero release.

Embodiment
Below in conjunction with specific embodiment, the present invention is further described.
Together referring to Fig. 1-7, mainly referring to Fig. 1.
Sessile algae is removed a device for aquaculture water inorganic salt, comprises the uncovered water tank in upper end 5, offers respectively water-in 4 and water outlet 1, and fix the rotating shaft 3 of a level on a pair of side of described water tank 5, and rotating shaft 3 is driven by reducing motor 2; If rotating shaft 3 directions are X-direction, level and be Y-direction perpendicular to the direction of X-direction; Fixing lamina affixad support 6 in described rotating shaft, described lamina affixad support 6 is hinged with the end face edge place of lamina affixad 8, and described lamina affixad 8 is strip, parallel with X-direction, the tooth bar of its two sides located level, periphtic algae on lamina affixad 8; Part lamina affixad 8 is positioned at water surface top, and part lamina affixad 8 is positioned at water surface below; Described casing 5 tops are fixedly installed the lamp source 7 of a pair of long strip shape along X-direction, light shines to lamina affixad 8.
The rectangular body of described water tank 5, its length and width is respectively along X, Y-direction, more compact structure, rationally.
Described water-in 4, water outlet 1 are positioned at rotating shaft below, are convenient to lamina affixad and carry out water lift.
Described lamina affixad support 6 is impeller shape, and lamina affixad support is simplified, and avoids shading.
The sway brace in fixed light source 8 and water tank 5 are connected as a single entity, and integrated structure is convenient to manufacture.
The addendum flank level of the tooth bar of described level, the addendum flank water lift effect of level is better.
The effect of the current that the technical program falls to causing by variation illumination intensity, the gravity that utilizes algae lamina affixad self, water naturally, thereby making the illumination that algae receives is constantly to change, thereby having imitated nature illumination makes algae reach ready-made assimilation effect, also can absorb the carbonic acid gas dissolving in water body by photosynthesis simultaneously, also can naturally drop and slough the obnoxious flavour in water body by current; Meanwhile, by algae lamina affixad, by naturally dropping all the time, keep vertical with horizontal plane, by rotating all the time the variation with changeless light source angulation and distance, simulated the irradiation of natural light; Meanwhile, by the roughness on algae lamina affixad, carry out water lift, water falls to causing again current naturally, thereby good living environment is provided to tack algae. the best effect of the inorganic salt that are absorbed.
20 revs/min of the rotating speeds of reducing motor are good, are conducive to algae and utilize light to change better to absorb inorganic salt.
The hydraulic detention time of Inlet and outlet water is the most suitable about 10 minutes, is conducive to inorganic salt in water body and is better absorbed.
This device have make simple, blowdown is convenient, it is low to invest, energy consumption is low, do not need back flushing, maintenance free, inorganic salt processing power advantages of higher.
