するにある。DETAILED DESCRIPTION OF THE INVENTION The present invention is characterized in that the outer peripheral edge 2 of the upper opening of the sewage treatment tank 1 and the inside of the sewage treatment tank 1 are formed by pickling low-grade coal with a weak acid and then neutralizing it. This relates to a malodor treatment device for sewage treatment characterized by disposing activated coal 3, and its purpose is to be able to reliably deodorize the malodor generated from the sewage treatment tank. An object of the present invention is to provide a malodor treatment device for sewage treatment that can effectively treat sewage.
本発明を以下実施例により詳述する。The present invention will be explained in detail below with reference to Examples.
図中１は汚水処理槽であって最初沈澱槽４と曝気槽５と
によって構成してあり、汚水処理槽１の上部は屋根６に
て密閉しである。In the figure, reference numeral 1 denotes a sewage treatment tank, which is initially composed of a settling tank 4 and an aeration tank 5, and the upper part of the sewage treatment tank 1 is sealed with a roof 6.

すようになったものである。Regarding activated coal 3, activated coal is made by pickling low-grade coal containing a large amount of ash (30% to 50%) with mineral acids having a content of 0.5% to 3%, and then neutralizing it. The ratio of fixed carbon to silicon, which is an insoluble substance, in coal is approximately 10:1 to 3.
The ratio of 100% to 100% is the same as that of natural ion-exchange resins.
このような活性化石炭はその全表面及び内部に灰分が溶

ニア等の有害ガスが消化されることとなる。By the way, if activated coal 3 such as air is placed on the outer peripheral edge 2 of the upper opening of the sewage treatment tank 1, the outer peripheral edge 2 will have moisture, creating an environment in which microorganisms can live well. Of course, since activated coal 3 is woody, it is an excellent nutrient for sleeping insects, sand bugs, blue greens, rotifers, amoeba, etc., and microorganisms can settle in the micropores. It serves as a suitable culture medium for microorganisms that can easily propagate, such as methyl mercaptan, mercaptan, hydrogen sulfide, sulfur dioxide gas, ammonia, etc., generated from the wastewater in the drowning tank 4 and the aeration tank 5 by the microorganisms living in the activated coal 3. Harmful gases will be digested.
また吸気口３からは新鮮な外部の空気が供給され、内部
の気体と混合されて活性炭フィルタ１０を通って外部に
排出される。Also, fresh external air is supplied from the intake port 3, mixed with internal gas, and discharged to the outside through the activated carbon filter 10.
この場合活性炭フィルタ１０によって臭気が吸着されて
外部に排出されることとなる。In this case, the activated carbon filter 10 absorbs the odor and discharges it to the outside.

しである。Activated coal 3 is laid in the initial settling tank 4 and aeration tank 5 that make up the sewage treatment tank 1, and the activated coal 3 absorbs and filters filth, and the microorganisms living in the activated coal 3 remove a large amount of filth from the sewage. It is used to treat wastewater by digesting it.

いものである。In addition, if activated coal 3 is also placed in the final settling tank 11 where sewage discharged from the aeration tank 5 is subjected to sedimentation treatment, the activated coal 3 absorbs and filters the sewage, and the microorganisms living in the activated coal 3 It may also be possible to make it digest the filth.
なお曝気槽５内には散気装置によって酸素を供給するよ

汚水を攪拌するようにしてもよい。Note that oxygen may be supplied into the aeration tank 5 by an aeration device, and the wastewater in the aeration tank 5 may be further agitated by a propeller or the like.

水処理を効果的にすることができるという利点がある。In the present invention, since the activated coal is arranged around the outer periphery of the upper opening of the sewage treatment tank, the activated coal becomes a suitable culture medium for microorganisms, which are generated from the sewage in the sewage treatment tank. Harmful gases such as methyl mercaptan, mercaptan, hydrogen sulfide, sulfur dioxide gas, and ammonia are digested by microorganisms, and the harmful and foul-smelling gases can be reliably deodorized, and pollution caused by odors during sewage treatment can be prevented. Furthermore, since the activated coal is placed inside the sewage treatment tank, there is an advantage that the activated coal placed inside the sewage treatment tank can make the sewage treatment more effective.
