では抜本的な臭気防止対策にはなり得ない。<Prior Art> Conventionally, when wastewater is purified by an aerobic biological treatment method, bad odors are mainly generated from pre-sedimentation tanks and anaerobic treatment tanks, which are pre-treatment equipment. These tanks are usually sealed with lids to prevent foul odors from leaking out, but since the inflow pipes and outflow pipes for sewage water are open, the odors inevitably enter the atmosphere. It will scatter. Therefore, the method of installing odor stacks and dispersing the odor from high places into the atmosphere has been adopted, but depending on the movement of the wind, the odor can drift all the way to the ground surface. It cannot be used as a countermeasure for odor prevention.

By setting the depth below the water surface of the transfer pipe that communicates from the pretreatment tank to the adjacent aerobic treatment tank to within twice the depth of the odor trap installed in the inlet pipe that leads wastewater to the pretreatment tank. The aim is to prevent bad odors from being dispersed into the atmosphere during the wastewater treatment process.

次に、本考案の一実施例を添付図面において説
明する。<Means for Solving the Problems> Next, an embodiment of the present invention will be described with reference to the accompanying drawings.
第１図は、本考案の防臭汚水処理装置の断面図
である。 FIG. 1 is a sectional view of the deodorizing sewage treatment apparatus of the present invention.

なるように設定する。 As shown in FIG. 1, the present invention is an odor-proofing sewage treatment device consisting of a pretreatment tank 1 and an aerobic treatment tank 2, in which sewage A is introduced into the inlet side of the pretreatment tank 1. An inflow pipe 3 is attached to the inflow pipe 3, and a deodorizing trap 4 having a sealing depth l is provided on the inflow pipe 3. Furthermore, a transfer pipe 5 communicating with the aerobic treatment tank 2 is attached to the outlet side of the pretreatment tank 1. The installation position of the transfer pipe 5 is as follows:
The depth L is set to be within twice the water sealing depth l of the inflow pipe 3.
第１図において、例えば防臭トラツプ４の封水

出して水面下の深さＬが零となると共に、封水深
さｌは2lと上昇して、トラツプ４の封水機能は維
持されている。 In FIG. 1, for example, when the water sealing depth l of the deodorizing trap 4 is set to 1/2 of the depth L below the water surface of the transfer pipe 5, anaerobic decomposition is performed in the pretreatment tank 1 in this state, When methane gas etc. is generated and the pressure inside the tank rises to lmmAg from atmospheric pressure, the wastewater in the pretreatment tank 1 flows into the aerobic treatment tank 2 and the depth L below the water surface becomes zero. At the same time, the water sealing depth l increases to 2l, and the water sealing function of the trap 4 is maintained.
この前処理槽１内の圧力がＬmmAgより更に上
昇すると、今度はメタンガス等が移送管５より好
気性処理槽２内に流出されると共に、トラツプ４

４を上昇して大気中に放出される。 When the pressure inside the pre-treatment tank 1 further rises above LmmAg, methane gas etc. will flow out from the transfer pipe 5 into the aerobic treatment tank 2, and the trap 4
The water sealing function of the trap is broken and methane gas and the like rise through the trap 4 and are released into the atmosphere.
従つて、ｌ＞Ｌ／２であればトラツプ４よりメ
タンガス等が大気中に放出されることがない。 Therefore, if l>L/2, methane gas etc. will not be released from the trap 4 into the atmosphere.
上記移送管５は、横Ｔ字型に形成し、図示の如

槽１内の水面に浮遊するスカムが好気性処理槽２
へ移行しないので好ましい。また、前処理槽１に
は蓋６を覆い密閉状態とすることが必要である。 If the transfer pipe 5 is formed into a horizontal T-shape and its upper open end protrudes above the water surface as shown in the figure, the scum floating on the water surface in the pretreatment tank 1 will be removed from the aerobic treatment tank 1.
This is preferable because it does not shift to . Furthermore, it is necessary to cover the pretreatment tank 1 with a lid 6 to keep it in an airtight state.
一方、好気性処理槽２には前処理槽１と連通す
る移送管５の吐出端上方に水面下に没するように
覆板７を取付ける。 On the other hand, a cover plate 7 is attached to the aerobic treatment tank 2 above the discharge end of the transfer pipe 5 communicating with the pretreatment tank 1 so as to be submerged below the water surface.
また、好気性処理槽２には充填材８を充填して

要は、好気性菌が付着繁殖しやすいように表面積
を大きく設計してなるものである。 Further, the aerobic treatment tank 2 is filled with a filler 8. The filler 8 is made of synthetic resin, and although not shown in the figure, it may be a block in which plate-like bodies with uneven surfaces are stacked in parallel, or may have a honeycomb shape or other shapes. It's okay,
In short, it is designed to have a large surface area so that aerobic bacteria can easily attach and propagate.

に生成した好気性菌との接触を促している。 In addition, an aeration device 10 is installed in the aerobic treatment tank 2, which can diffuse the air blown from the blower 9 from below the filling material 8. Water circulates and filler 8
This encourages contact with aerobic bacteria generated in
好気性処理槽２で浄化処理された処理水Ｂは流
出管１１より放流する。 The treated water B purified in the aerobic treatment tank 2 is discharged from the outflow pipe 11.

る。<Effects of the invention> As described above, the deodorizing sewage treatment device of the present invention not only removes pollutants such as BOD, but also reduces the depth below the water surface of the transfer pipe to twice the sealing depth in the inlet pipe. It is a simple deodorizing means that can be set to a depth within 100 degrees, eliminating the need to install special deodorizing equipment, making it an extremely economical deodorizing device.
