本考案は、回転ロータ型の表面曝気装置を設け
た生物処理装置に関するものである。[Detailed Description of the Invention] The present invention relates to a biological treatment device equipped with a rotating rotor type surface aeration device.

じ、水面付近では流速が大きい底面では非常に小
さくなるので、流下水の槽内滞留時間が不均一と
なり生物処理効果が不安定になるなどの問題点が
あつた。 Conventionally, there are biological treatment devices such as oxidation detches that have a rotating rotor-type surface aeration device installed on the water surface of the aquarium that serves both water flow and aeration, but this surface aeration device has only a part of it below the water surface. Because the tank is submerged, uneven water flow velocity occurs in the depth direction of the tank, and the flow velocity is high near the water surface, but very low at the bottom, resulting in uneven residence time in the tank and unstable biological treatment effect. There were some problems, such as:
本考案は、このような問題点を解消する生物処

槽内の水面に回転ロータ型の表面曝気装置を配置
すると共に、回転ロータの下流における水の速度
分布を均一化するために、前記表面曝気装置下方
の槽水深を浅くした生物処理装置である。 The purpose of the present invention is to provide a biological treatment device that solves these problems.
In this biological treatment device, a rotor-type surface aeration device is arranged on the water surface in the tank, and the depth of the tank water below the surface aeration device is made shallow in order to equalize the water velocity distribution downstream of the rotor.
本考案の一実施例を図面について説明すれば、

いる構造のものを適用することができる。 An embodiment of the present invention will be explained with reference to the drawings.
Reference numeral 1 denotes a biological treatment tank, and near the water surface in this tank 1, a surface aeration device 2 having a rotating rotor partially immersed in the water surface is provided. As this surface aeration device 2, a water wheel-like device having a cylindrical body with blades installed radially as shown in the figure, or a device having a conventional structure can be applied.
上記表面曝気装置２直下の槽１底盤には、槽１
の両方の側壁内面にまたがるコンクリートにより
構成したもぐり堤３が固定配備されている。この
もぐり堤３は流下水の上流側が上り勾配に、下流
側が下り勾配となつており、頂上部（表面曝気装
置２の直下に位置している）は水平である。 The tank 1 bottom panel directly below the surface aeration device 2 has a
A breakwater bank 3 made of concrete is fixedly provided and extends over the inner surfaces of both side walls. This dike 3 has an upward slope on the upstream side of the flowing sewage, a downward slope on the downstream side, and the top portion (located directly below the surface aeration device 2) is horizontal.
しかして、表面曝気装置２の回転ロータを回転

面の上方において水流の速度分布が均一化され、
したがつて槽１内の水の滞留時間がより均等化さ

きる。 Therefore, by rotating the rotor of the surface aeration device 2, it is possible to dissolve oxygen in the air into the water and carry out aeration treatment, while at the same time transporting the water downward. As a result, the depth of the water in the tank 1 becomes shallower in the installation part, and the velocity distribution of the water flow is made uniform above the top surface of the dike 3.
Therefore, the residence time of water in the tank 1 is made more equal, and as a result, the efficiency of biological treatment can be improved.
なお、本考案においては、上記もぐり堤３は中
空のものでもよく、プラスチツク材料で構成する

ように製作してもよい。 In addition, in the present invention, the breakwater bank 3 may be hollow, or may be made of plastic material and may be provided so as to be easily removed.
Alternatively, the tank 1 may be manufactured from the beginning so that its bottom plate is shallow at one or several locations (a surface aeration device is provided at each location).
さらに本考案においては、槽内水が上記表面曝

上部を流下するように設けることが好ましい。し
たがつて、屈曲板を槽底面から離隔して設けたの
では十分な効果は得られない。 Furthermore, in the present invention, it is preferable that when the water in the tank flows down below the surface aeration device, the entire amount flows down the top of the dike. Therefore, if the bending plate is provided at a distance from the bottom of the tank, a sufficient effect cannot be obtained.
以上述べたように本考案によれば、槽内の水の
流動が均一化されるので水の槽内滞留時間も均等
となり、したがつて生物処理の効率が向上する効
果が得られる。 As described above, according to the present invention, since the flow of water in the tank is made uniform, the residence time of water in the tank is also made equal, and therefore the efficiency of biological treatment can be improved.
