Embodiment
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar the content disclosed by this specification sheets can understand other advantages of the present utility model and effect easily.
Refer to Fig. 1 to Fig. 4.Notice, structure, ratio, size etc. that this specification sheets institute accompanying drawings illustrates, content all only in order to coordinate specification sheets to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionlity or size, do not affecting under effect that the utility model can produce and the object that can reach, still all should drop on technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, quote in this specification sheets as " on ", D score, "left", "right", " centre " and " one " etc. term, also only for ease of understanding of describing, and be not used to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of the utility model.
As shown in Figures 1 to 4, the utility model provides a kind of wind and wave resistance ecological bed of diving under water, overall in highly faired hull shape, open top, the dive bottom of bed of described ecology is bearing stratum 1, and the below of described bearing stratum 1 is provided with air-permeable layer 2, and the top of described bearing stratum 1 is provided with immovable bed 4, hypothallus 3 is provided with, for waterplant breeds district 5 above described hypothallus 3 between described immovable bed 4 and described bearing stratum 1.
Further, described bearing stratum 1 inside is filled with filler.Support matrix layer can be played, prevent air-permeable layer from blocking, be convenient to the functions such as attached microbial.
Further, the diameter of described filler is 8-16mm.Described filler can adopt stone.
Further, described air-permeable layer 2 is in netted, and surface arrangement has multiple breather hole.Be convenient to the exchange of vertical current, air.
Further, microbiological culture media is established in described hypothallus 3.Microbiological culture media is positioned at water bottom more easily with bed mud and water body reacts and Stability Analysis of Structures is easy to Microorganism incubation, is conducive to the growth promoting microorganism and plant, the shortening microorganism colonization time, enhances the removal effect to the N/P in water.
