【発明の詳細な説明】
（産業上の利用分野）
本発明は各種産業で排出される複合廃液の処理方法に関
するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for treating composite waste liquid discharged from various industries.
複合廃液とは、有機物、無機物、水、重金属。Complex waste liquid consists of organic matter, inorganic matter, water, and heavy metals.
酸、アルカリ等が一定せず様々に含有している産業廃液
をいう。Industrial waste liquid that contains various acids, alkalis, etc.
（従来技術）
複合廃液は、上記のように含有物が一定でないためその
処理には、まづ廃液の含有成分を調べた後、廃液に応じ
た処理をする必要があった。(Prior Art) As mentioned above, the contents of a composite waste liquid are not constant, so in order to treat it, it is necessary to first examine the components contained in the waste liquid, and then perform treatment according to the waste liquid.
また、複合廃液中には、有機物、無機物、金属、重金属
等の人体に悪影響のある物質が含有されているので、公
害上の問題もありその処理は慎重に行う必要があった。Furthermore, since the composite waste liquid contains substances that are harmful to the human body, such as organic substances, inorganic substances, metals, and heavy metals, there is a problem of pollution, and it is necessary to carefully dispose of it.
そこで、この種複合廃液の処理として、一般的には、先
づ前処理を行ったのち、処理液に希釈。Therefore, in the treatment of this type of composite waste liquid, it is generally pretreated first and then diluted into a treatment liquid.
凝集剤を注入し、その後湿式水処理又は乾式水処理等の
物理的、化学的処理を行い、さらにその時発生する臭気
は脱臭処理を行うという方法が行われている。A method is used in which a flocculant is injected, and then physical and chemical treatments such as wet water treatment or dry water treatment are performed, and the odor generated at that time is further deodorized.
（発明が解決しようとする課頭）
このように従来方法は、廃液に応じた処理をしなければ
ならないので非常に手間の係るものであり当然処理コス
トが高くなるものであった。しかも、処理行程中に発生
する臭気により悩まされることがあった。(Problem to be Solved by the Invention) As described above, in the conventional method, treatment must be carried out according to the waste liquid, which is very time-consuming and naturally increases the treatment cost. Moreover, the odor generated during the treatment process has caused problems.
（課題解決の手段）
本発明は、いかなる複合廃液であっても処理が出来るよ
うにしたものであるだけでなく、処理液中の有用生成物
を有効に利用するとともにコストの低減を図り臭気の脱
臭をも同時に行う処理方法に関するものである。(Means for Solving Problems) The present invention not only makes it possible to treat any composite waste liquid, but also effectively utilizes useful products in the treated liquid, reduces costs, and eliminates odors. The present invention relates to a treatment method that also performs deodorization at the same time.
すなわち、バッチ式処理釜と燃焼室とをエジェクター機
能を有する送気管で連結してなる釜内に、処理廃液を投
入したのち、釜内を５００〜７゜０℃に昇温し釜内の酸
素を追い出すとともに釜内で発生したガスを送気管より
燃焼室に送気し、７５０〜１０００℃、滞留時間３秒以
上で燃焼し、加熱源の一部とするとともに同時に脱臭を
も行うことを特徴とするものである。That is, after the treated waste liquid is put into a pot formed by connecting a batch-type processing pot and a combustion chamber with an air pipe with an ejector function, the temperature inside the pot is raised to 500 to 70°C, and the oxygen in the pot is removed. At the same time, the gas generated in the pot is sent to the combustion chamber from the air supply pipe, where it burns at 750 to 1000°C with a residence time of 3 seconds or more, serving as a heating source and deodorizing at the same time. That is.
（作用） 本発明の作用は以下の通りである。(effect) The effects of the present invention are as follows.
バッチ式処理釜に複合廃液を投入し加熱すると、釜内が
５００〜７００℃になると処理液中の水分は水蒸気とな
り、油分等の有機物はガス化するとともに、金属等の含
有無機物は乾燥し残渣物となり釜内に残る。そして、水
蒸気及び発生ガスは燃焼室に送り込まれ、水蒸気は蒸発
し、発生ガスは補助燃料として利用できる。When the composite waste liquid is put into a batch-type processing pot and heated, when the temperature inside the pot reaches 500 to 700℃, the water in the processing liquid becomes steam, organic substances such as oil are gasified, and inorganic substances such as metals are dried and a residue is formed. It becomes a substance and remains in the pot. The water vapor and generated gas are then sent into the combustion chamber, where the water vapor evaporates and the generated gas can be used as auxiliary fuel.
（発明の効果）
本発明は以上のような方法によるため種々の複合廃液の
蒸留、乾留、脱臭処理を一気に行うことができることと
なる。(Effects of the Invention) Since the present invention uses the method described above, it is possible to perform distillation, carbonization, and deodorization treatments of various composite waste liquids all at once.
すなわち、バッチ式釜内が５００〜７００℃に昇温する
と処理液は熱分解を開始するが、処理釜と燃焼室とはエ
ジェクター機能を有する送気管と連通されているため処
理釜内は負圧（−２００−ΔＱ）となり処理液の反応促
進を図ることができる。In other words, when the temperature inside the batch type pot rises to 500 to 700°C, the processing liquid starts to thermally decompose, but because the processing pot and combustion chamber are connected to an air supply pipe that has an ejector function, there is a negative pressure inside the processing pot. (-200-ΔQ), which makes it possible to promote the reaction of the treatment liquid.
また、処理液中の水分及び有機物は、それぞれ水蒸気と
可燃ガスとなり送気管により燃焼室に送り込まれる。そ
して、水蒸気は燃焼室内で直ちに蒸発し、一方可燃ガス
は燃焼室内で７５０〜１０００℃、滞留時間３秒以上で
燃焼されるため車番こ加熱源の補助燃料として利用され
るだけでなく。Further, the moisture and organic matter in the processing liquid become water vapor and combustible gas, respectively, and are sent into the combustion chamber through the air pipe. The water vapor evaporates immediately in the combustion chamber, while the combustible gas is burned in the combustion chamber at a temperature of 750 to 1000°C for a residence time of 3 seconds or more, so it is not only used as an auxiliary fuel for the heating source of the vehicle.
同時にガスの臭気分も燃焼室内において燃焼醸化脱臭さ
れることとなる。At the same time, the odor components of the gas are also combustion-enriched and deodorized in the combustion chamber.
さらにまた、処理液中の有機物類は乾留されるので、排
気筒から排出するＮ０Ｘ（窒素酸化物）量は、激減し２
０〜５０ｐｐｍの範囲であった。Furthermore, since the organic substances in the treatment liquid are carbonized, the amount of NOX (nitrogen oxides) emitted from the exhaust stack is drastically reduced.
It was in the range of 0 to 50 ppm.
煤ａｊｉもａ減り、、０．００１ ｇ／Ｎ３−０．００
３ ｇ／Ｎ３の範囲であった。Soot aji also decreases, 0.001 g/N3-0.00
It was in the range of 3 g/N3.
（実施例）

ことができる。(Example) In the case of waste liquid containing salt, #CI, sulfur S, etc., HCl and SOx can be reduced by 20% by mixing an appropriate amount of neutralizing chemicals such as caustic soda and lime with the waste liquid and then treating it according to the present invention. ~5
It is within the range of 0 ppm, and pollution problems can be completely eliminated.
ＣＮ廃液を処理した場合、ガス化したＣＮは燃焼室内で
炭素Ｃと窒素Ｎに分解されるので無害化処理ができる。When CN waste liquid is treated, the gasified CN is decomposed into carbon C and nitrogen N in the combustion chamber, so that it can be rendered harmless.
Ｃｒ”を含む廃液を処理した場合には、釜内の還元作用
によりＣｒ”がＣｒ”に変化するので六価クロムの含有
にはａ減した。すなわち、処理前８ｐｐｍあったものが
処理後は２ｐｐｍになっていた。When waste liquid containing "Cr" is treated, Cr" changes to Cr" due to the reducing action in the pot, so the content of hexavalent chromium is reduced by a. In other words, what was 8 ppm before treatment is reduced to It was 2ppm.
