The air of micro air bubble form is supplied from air injection tube 114 to air injection device 112.Air injection tube 114 It is connected with the pressure fan 116 outside pond 110, to supply air.It is supplied by pressure fan 116 to air injection device The amount of 112 air can be adjusted by the control signal of control device (with reference to the reference numeral 180 of Fig. 4).

The ceramics that air injection device 112 can be equivalent to Porous (are molded quartz sand or carborundum particle, are burnt Tie) air-dispersing plate or diffuser or the snorkel in hole that is provided with nozzle form etc..

Vertical-type blender 120 is vertically located at the horizontal centre in pond 110, to stream under formation.With reference to figure 1, with dotted line arrow Head shows the flowing of the fluid formed by vertical-type blender 120.It is vertical due to the horizontal centre by being located at pond 110 Type blender 120 is formed lower to stream, and symmetrical fluid flowing is formed in the inside in pond 110.In the process, it is noted by air The air for entering the injection of device 112 is transferred to after the bottom surface in pond 110, is risen along the vertical interior wall surface in pond 110, is then passed through The lower bottom surface that pond 110 is re-circulated to stream formed from vertical-type blender 120.Air circulation in this way, by air The entire inside in pond 110 is transferred uniformly into, so as to make dissolved oxygen amount (DO) uniform.In addition, by the entire interior of pond 110 Portion keeps uniform dissolved oxygen amount, uniform microorganism concn is kept in entire pond 110, so as to realize the optimization of aerobic tank Operation.

Vertical-type blender 120 includes bar 122 and impeller 124.As illustrated in fig. 1, bar 122 is parallel to the height in pond 110 Spend direction.The upper end of bar 122 is combined with motor and change gear (not shown) etc..And the lower end of bar 122 is combined with Multiple impellers 124.

Can have at least one dissolved oxygen (DO) sensor in the inside in pond 110.118 cell of dissolved oxygen sensor Aerobic tank control device is passed to after dissolved oxygen amount inside 110 (with reference to the reference numeral 180 of Fig. 4).Control device can Keep constant the dissolved oxygen amount inside pond 110 according to the dissolved oxygen amount measured value inside pond.

Dissolved oxygen sensor 118 can be located at the top and lower part in pond 110 respectively.In addition, the top in pond 110 with And lower part, it can also be respectively positioned at the horizontal centre and sidewall sections in pond 110.In this way, the position by dissolved oxygen sensor 118 The horizontal centre in the vertical upper in pond 110 and lower part and pond 110 and side is configured, so as to judge whether to pond Supply air to 110 inner homogeneous.

Fig. 2 is to exemplify the figure of aerobic tank 140 that the utility model second embodiment is related to.

With reference to figure 2, the aerobic tank 140 that second embodiment is related to includes pond 142, pressure fan 148, dissolved oxygen sensor 150 And vertical-type blender 152, the pond 110 of these aerobic tanks 100 being related to first embodiment, pressure fan 116, dissolved oxygen pass Sensor 118 and vertical-type blender 120 are identical, therefore omit specific description.

The aerobic tank 140 that second embodiment is related to is characterised by comprising air concentration basin 144, air to be replaced to inject Device 112, the air concentration basin 144 make the high concentration micro air bubble solution of air supersaturation dissolving and formation for storing. In the inside of air concentration basin 144, air is supplied by pressure fan 148, so as to be dissolved into hypersaturated state.And it is stored in sky High concentration micro air bubble solution in gas concentration basin 144 is supplied to the upper of pond 142 by pump 154 and air injection tube 146 Portion.

By the way that high concentration micro air bubble solution to be put into the inside of aerobic tank 140, compared to existing air diffusion apparatus, energy Enough improve the dissolved efficiency of oxygen (or ozone).

Vertical-type blender 152 forms lower to stream, the flowing of resulting fluid (including air) in the inside in pond 142 As the dotted line arrows.Fluid flow inside this aerobic tank 100 being related to first embodiment is same.

Fig. 3 is to exemplify the figure of aerobic tank 160 that the utility model 3rd embodiment is related to.

With reference to figure 3, the aerobic tank 160 that 3rd embodiment is related to includes pond 162, pressure fan 174, dissolved oxygen sensor 170 And vertical-type blender 172, the pond 110 of these aerobic tanks 100 being related to first embodiment, pressure fan 116, dissolved oxygen pass Sensor 118 and vertical-type blender 120 are identical, therefore omit specific description.

The aerobic tank 160 that 3rd embodiment is related to is characterized in that having the oxygen tank for storing high-concentration oxygen 164.Purity oxygen or the oxygen of high concentration are stored in oxygen tank 164, is carried out by pressure fan 174 from the top in pond 162 Supply.Oxygen tank 164 can be only fitted to the top in pond 162.

The oxygen supplied from oxygen tank 164 can be supplied uniformly across entire to pond 162 by vertical-type blender 172 It is internal.

The oxygen tank 164 of storage high-concentration oxygen can realize miniaturization, therefore have and be free to select its configuration bit The advantages of putting.Although instantiating the aerobic tank 100 that first embodiment is related to only has air injection device 112, this practicality is new The aerobic tank that another embodiment of type is related to can also be provided simultaneously with air injection device 112 and air concentration basin 144.Such as This, is provided simultaneously with air injection device 112 and air concentration basin 144, so as to increase dissolved oxygen amount.

Fig. 4 is the figure for exemplifying aerobic tank control device 180.

With reference to figure 4, first embodiment to the 3rd embodiment that aerobic tank control device 180 is applicable to the utility model relates to And aerobic tank 100,140,160, can realize aerobic tank optimization stirring.

Aerobic tank control device 10 from dissolved oxygen sensor 118,150,170 receive signal, with grasp pond 110,142, Dissolved oxygen amount inside 162, and based on this control pressure fan 116,148,174 and vertical-type blender 120,152,172, thus The dissolved oxygen inside pond 110,142,162 is enable to keep uniform state more than appropriate value.

It is illustrated above by reference to an embodiment of the utility model, but those of ordinary skill in the art can manage It solves, it is new to this practicality in the range of the thought of the utility model that can be recorded in claims are not departed from and field Type is carry out various modifications and is changed.
