Guide is located in the body of said pond, and the direction that an end of said guide is arranged on the said aeration tube and the water surface of said guide edge and said sewage tilts extends upward, and the said guide in said oxygenous bubble edge moves.
In a preferred embodiment, said guide comprises first shoe and second shoe, and the edge of said first shoe is connected with the edge of said second shoe, and the xsect of said guide is in the shape of the letter V.
In a preferred embodiment, said first shoe and second shoe are symmetrically arranged rectangle.
In a preferred embodiment, said first shoe and second shoe are symmetrically arranged trapezoidal, and said trapezoid width increases along the direction near the water surface gradually.
In a preferred embodiment, the xsect of said guide is circular arc.
In a preferred embodiment, the one side of said guide body bottom towards said pond is provided with a plurality of thrusts that are used to cut apart said oxygenous bubble.
In a preferred embodiment, offer the through hole that allows the oxygenous bubble of part to pass on the said guide.
In a preferred embodiment, the edge indentation of said guide.
In a preferred embodiment, said guide is a plurality of, and said a plurality of guides are parallel to each other, and are arranged at equably on the said aeration tube.
In a preferred embodiment, said aeration head has a plurality of, and is arranged at equably on the said aeration tube.
In the above-mentioned bio-aeration pool; The upwardly extending guide of direction that one end is arranged on the aeration tube and the water surface of edge and sewage tilts, the oxygenous bubble that makes oxygen-containing gas form through aeration head moves along guide, thereby increased oxygenous bubble in the pond intravital moving displacement; Promptly prolonged oxygenous bubble in the pond the intravital time; Improved the utilization ratio of oxygen, therefore, above-mentioned bio-aeration pool can improve the utilization ratio of oxygen.

[embodiment]
Further specify below in conjunction with accompanying drawing and specific embodiment.
As shown in Figure 1, the bio-aeration pool 100 of an embodiment comprises pond body 110, aeration tube 120, aeration head 130 and guide 140.
Please in the lump with reference to Fig. 2 and Fig. 3, guide 140 is located in the pond body 110, and the direction that an end of guide 140 is arranged on the aeration tube 120 and the water surface of guide 140 edges and sewage tilts extends upward, and oxygenous bubble moves along guide 140.Thereby increased the moving displacement of oxygenous bubble in pond body 110, made oxygenous bubble increase, promptly increased the oxygen content in the sewage, promoted the purification of mikrobe sewage in the hydrogymnastic time of dirt.In the present embodiment, guide 140 is a plurality of, and a plurality of guides are parallel to each other, and are arranged at equably on the aeration tube 120.Guide 140 can impel the sewage directed flow in the pond body 110, thereby impels the mud that contains mikrobe in the sewage in sewage, to disperse, and impels it comparatively to be evenly dispersed in the sewage, improves the utilization ratio of oxygen.The material of guide 140 can be preferably the organic polymer material for anti-aging, uncorruptible materials such as organic polymer material, stainless steels, and for example PVC is anti-aging, and cost is low.In the present embodiment, guide 140 is littler 0.5 meter or equal liquid level than the liquid level of sewage in the pond body 110 away from the distance of end body 110 bottoms to the pond of pond body 110 bottoms, not only satisfies guide effect, also can not cause the wasting of resources.Guide 140 comprises that the edge of first shoe 142 and second shoe, 144, the first shoes 142 is connected with the edge of second shoe 144, is in the shape of the letter V the xsect of guide 140.The guide 140 of V font helps making oxygenous bubble to move along guide 140.In the present embodiment, first shoe 142 and second shoe 144 are symmetrically arranged rectangle.Be appreciated that guide 140 also can be flat, or other can play the structure of guide effect.The one side of guide 140 body 110 bottoms towards the pond is provided with a plurality of thrusts 146 that are used to cut apart oxygenous bubble.In the oxygenous uphill process that ducks in drink, some oxygenous steeping oneself-meeting flocks together, and forms air pocket; Thereby reduced the utilization ratio of oxygen; The air pocket that thrust 146 will contain oxygen scratches and is divided into small bubbles, thereby increases the specific surface area of oxygenous bubble, has improved the utilization ratio of oxygen.Thrust 146 can be needle-like, dentation etc., is preferably needle-like, thrust 146 intensive being distributed on the guide 140.Offer the through hole 148 that allows the oxygenous bubble of part to pass on the guide 140.The oxygenous bubble of a part moves along guide 140, and the oxygenous bubble of another part passes through hole 148, makes oxygenous bubble be full of pond body 110.Through hole 148 intensive being distributed on the guide 140, and the distance between per two through holes 148 is 5～10 millimeters.Through hole 148 can prevent because guide 140 guide effects make the oblique upper of guide 140 not have oxygenous bubble or a small amount of oxygenous bubble.In the present embodiment, the aperture of through hole 148 is less, is roughly 1～3 millimeter greatly; Only allow less oxygenous bubble to pass; And bigger bubble can not pass through, and bigger bubble can only move along guide 140, and is directed to thrust 146 on the part 140 and scratches and be divided into small bubbles.The edge indentation of guide 140.Thereby the air pocket that will contain oxygen scratches and is divided into small bubbles, thereby increases the specific surface area of oxygenous bubble, has improved the utilization ratio of oxygen-containing gas.
Like Fig. 4 and shown in Figure 5, in other embodiments, first shoe 142 of guide 140 and second shoe 144 are symmetrically arranged trapezoidal, and the trapezoid width increases along the direction near the water surface gradually.
Like Fig. 6, shown in 7 and 8, in other embodiments, guide 140 also can be the semi arch structure.
In the above-mentioned bio-aeration pool 100; The upwardly extending guide 140 of direction that one end is arranged on the aeration tube 120 and the water surface of edge and sewage tilts makes oxygen-containing gas through aeration head 130 and the oxygenous bubble that forms moves along guide 140, thereby has increased the moving displacement of oxygenous bubble in pond body 110; Promptly prolonged the time of oxygenous bubble in pond body 110; Improved the utilization ratio of oxygen, therefore, above-mentioned bio-aeration pool 100 can improve the utilization ratio of oxygen.
In addition, above-mentioned bio-aeration pool 100 is simple in structure, is convenient to install.
The above embodiment has only expressed several kinds of embodiments of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
