するおそれがあった。However, in the conventional air diffuser for such a septic tank, even if the diffuser pipe is installed almost horizontally with respect to the floor when the diffuser pipe is attached to the septic tank, the level of the diffuser tube is different from each other. If there is any difference in the air diffuser, no matter how much the air supply valve opening is adjusted to finely adjust the amount of air diffused, the air will flow to the higher level (to the inclined side) of the floor of the air diffuser. It was extremely difficult to perform uniform air diffusion over the entire surface of the biofilm filtration tank due to the phenomenon of deviation. Further, there is a possibility that foreign matters such as dust may enter the diffuser tube through the diffuser hole opened downward.

現地でも散気管の水平度の微調整を必要としその据付け
に手数がかかった。In particular, when the air diffuser used in a domestic septic tank is applied to a small, medium, or large-scale combined septic tank, the capacity of the biofilm filtration tank is large and the supply pressure of diffused air is low. Due to the low levelness of the foundation of the installation machine, even if there is some deviation in the horizontal direction of the air diffuser, the amount of air diffused from the air diffuser tends to be uneven. for that reason,
Even in the field, it was necessary to fine-tune the level of the air diffuser and to install it.

It is an object of the present invention to provide an air diffuser capable of uniformly diffusing over the entire biofilm filtration tank of the septic tank even if there is an inclination, and which does not require local fine adjustment.

ルでの実験により求めた。An air diffuser 22 as shown in FIGS. 2 and 3 was used for this air diffusion experiment. The air diffusing device 22 is constructed by assembling the air diffusing tube 22b into a letter-like shape via the elbow 22c, and air is directed downward at a right angle to the air diffusing tube 22b at one end in the XX 'direction (the radial direction of the biofilm filtration tank). The supply pipe 22a was connected. Further, as shown in FIG. 3 in particular, the air diffuser 22b is connected to the air supply pipe 22a from the horizontal plane by θ (+), θ.
The air outlet (air diffuser) was tilted in the (-) direction, and the position of the air outlet (air diffuser) was set to face upward or downward. Here, the diameter d of the air diffuser 22b is 13 to 3
0mm, as the size of the air outlet (2mm, 3mm diameter),
Air was supplied from a blower at 140 liters / minute, and the maximum inclination angle θ of the air diffuser 22b capable of uniformly diffusing was obtained by an experiment in this pool.

できることが実証されたことになる。The results of this pool experiment are shown in FIG. 4 as the results of the aeration experiment. That is, the abscissa of this graph shows the air diffuser diameter (mm), the diameter of the air outlet (2 mm, 3 mm) and its direction (upward, downward), and the vertical axis shows the inclination angle θ from the horizontal plane. According to the results of this experiment, it was found that the inclination angle θ can be increased irrespective of the diameter of the diffuser pipe when the air outlet has a diameter of 2 mm and the direction of the air outlet is upward from the horizontal plane. That is, since θ can be set large, it is proved that a deviation (tilt) can be absorbed at the time of construction and installation of the air diffuser, and uniform air diffusion can be performed without fine adjustment during installation.

(± 1/100 inclination), the air outlet has a diameter of 2 mm, and the outlet is set upward so that uniform air diffusion is achieved. On the contrary, in this case, as shown in FIG. 6, the air diffuser 22b is directed downward (θ
It is not a good idea to incline (-) and set the air outlet to face downward.

The blocks are configured by connecting the air diffuser pipes 22b by the elbows 22c, and the air supply pipes 22a are arranged along each block, and are connected to the blower 35 via the air supply valve 36 to supply air for air diffusion.

The air diffuser 22b is preset upward (θ (+)) from the horizontal plane via the elbow 22c so that the supply end of 2a is on the lower side with a gradient of, for example, θ = 0.6 °. Due to this inclination θ, deviation during normal installation (± 1/200)
Is absorbed and does not affect the uniform air diffusion. In particular, as shown in FIG. 9, the air diffuser 22b (caliber 2
0 to 25 mm), for example, 52 air outlets 38 (2 mm in diameter) are formed upward, and a dust fall prevention plate (eave) 37 disposed immediately above the air outlet 38 is used to remove dust and the like. The invasion of foreign matters into the air diffuser 22b is prevented.

る。When the air diffuser 22 of the present invention thus constructed is installed in the septic tank 1, the deviation from the horizontal plane in the YY 'direction (axial direction) is directed upward from the horizontal plane to the air diffuser 22 in advance. Since there is a gradient of about 1/100 of the above, even if there is a deviation of about ± 1/200, this deviation is absorbed by the gradient of 1/100 of the previous one, and the air is evenly distributed in the biofilm filtration tank. 4 will be diffused over the entire surface. The deviation in the XX 'direction (the radial direction of the biofilm filtration tank) is adjusted by manually opening and closing the air supply valves 36 individually to adjust the air supply amount.

The amount of air diffused in each direction is XX 'in the respective air supply pipes 2.
2a, the opening degree of the air supply valve 36 is adjusted, and the air diffusion amount in the YY 'direction is set to a preset angle (0.5 to 0.5) as shown in FIG. 10 °)
When installing in the septic tank 1 so that the air supply port (end) of the air supply pipe 22a is set to the lower side of the air diffuser pipe 22b in advance.
For example, it is set in the −Y ′ direction with an inclination of θ 0 = 1/200. As a result, even if the horizontal error of the inclination of 1/200 is θ = ± 0.3 °, uniform air diffusion is possible over the entire surface of the biofilm filtration tank.
