ところで、紙、プラスチック、生ごみ、し尿、浄化槽汚泥等の一般廃棄物や下水処理汚泥を含む有機性廃棄物を再資源化するには以下のような課題がある。
一般廃棄物の処理において、生ごみ、食品廃棄物等のリサイクル価値は広く知られているが、生ごみ類は紙、プラスチック等からなる袋、容器類とともにポリエチレン袋等に入れられて排出される。このため、生ごみ、食品廃棄物等を堆肥化、バイオマス化する際には紙等の混入物の分別が必要であるが、生ごみ、食品廃棄物等と紙、プラスチック等とを分別することは技術的および作業手間的に困難性が伴う。また、生ごみ、食品廃棄物等を堆肥化、バイオマス化する際には、腐敗臭等の臭気対策および雑菌対策が必要である。また、特許文献１に記載するものでは、対象物が生ごみ有機成分分解後の汚泥が主となるために、処理後に得られる再資源化原料において低位発熱量３５００ｋｃａｌ／ｋｇ以上を維持することは困難な場合が多い。 By the way, there are the following problems in recycling organic waste including general waste such as paper, plastic, garbage, human waste, septic tank sludge, and sewage treatment sludge.
In the treatment of general waste, the recycling value of garbage, food waste, etc. is widely known, but the garbage is discharged in a polyethylene bag together with bags and containers made of paper, plastic, etc. . For this reason, when composting and biomassing garbage, food waste, etc., it is necessary to separate contaminants such as paper, but separating garbage, food waste, etc. from paper, plastic, etc. Is technically and labor intensive. In addition, when composting food waste, food waste, etc. into compost or biomass, countermeasures against odors such as spoilage odor and various germs are necessary. Moreover, in what is described in Patent Document 1, since the object is mainly sludge after decomposition of garbage organic components, maintaining a low heating value of 3500 kcal / kg or more in the recycled material obtained after treatment Often difficult.

一方、し尿、浄化槽汚泥等を処理する汚泥再生処理センターにおける水処理施設から排出される水処理脱水汚泥等も発熱量が低く再資源化が困難である。このため、一般廃棄物を助燃材化、堆肥材化するには加熱等の処理が必要である。   On the other hand, water treatment dewatered sludge discharged from a water treatment facility in a sludge regeneration treatment center for treating human waste, septic tank sludge, etc. has a low calorific value and is difficult to recycle. For this reason, processing such as heating is necessary to convert general waste into a combustion aid and compost.

本発明は、紙、プラスチック、生ごみ等を分別を必要とせずに衛生的に処理することができ、生産物である乾燥粉末により汚泥再生処理センターから排出する水処理脱水汚泥の助燃材、堆肥材としての質の向上を図ることができ、処理過程において生じる蒸気含有排ガスを汚泥再生処理センター等の水処理施設において有効活用することができる有機性廃棄物処理システムを提供することを目的とする。   INDUSTRIAL APPLICABILITY The present invention is capable of hygienically treating paper, plastics, garbage, etc. without requiring separation, and is a water-treated dewatered sludge auxiliary material, compost discharged from a sludge recycling treatment center by dry powder as a product. The purpose of the present invention is to provide an organic waste treatment system that can improve the quality as a material, and can effectively use steam-containing exhaust gas generated in the treatment process in water treatment facilities such as a sludge regeneration treatment center. .

上記課題を解決するために、本発明の有機性廃棄物処理システムは、反応容器内に飽和水蒸気を供給して原料となる固形状有機性廃棄物を亜臨界反応により乾燥粉末化する固形状有機性廃棄物処理工程と、原料となる液状有機性廃棄物を水処理し、前記水処理により得る処理汚泥を脱水して脱水汚泥を得る液状有機性廃棄物処理工程とを備え、固形状有機性廃棄物処理工程の生産物の乾燥粉末材と液状有機性廃棄物処理工程の生産物の脱水汚泥もしくは乾燥汚泥とを混合して再資源化材を得ることを特徴とする。   In order to solve the above-described problems, the organic waste treatment system of the present invention is a solid organic material that supplies saturated water vapor into a reaction vessel and pulverizes the solid organic waste as a raw material into a dry powder by a subcritical reaction. A solid organic property, and a liquid organic waste treatment step for treating a liquid organic waste as a raw material with water and dehydrating the treated sludge obtained by the water treatment to obtain a dehydrated sludge. It is characterized by mixing the dry powder material of the product of the waste treatment process and the dehydrated sludge or dry sludge of the product of the liquid organic waste treatment process to obtain a recycled material.

上記した構成において、固形状有機性廃棄物および液状有機性廃棄物は、例えば一般廃棄物である紙類、プラスチック、生ごみ、し尿、浄化槽汚泥、選定枝等である。
固形状有機性廃棄物処理工程では、固形状有機性廃棄物である生ごみ、プラスチック等の有機性廃棄物を反応容器内に供給し、反応容器内に飽和水蒸気を導入して、運転条件：常温〜２３５℃、常圧〜３ＭＰａ、昇温昇圧時間１〜３時間、最大温度圧力保持時間５分以上で亜臨界反応（亜臨界状態での水熱反応）させて、蒸気間接加熱等により乾燥粉末化させる。 In the above-described configuration, the solid organic waste and the liquid organic waste are, for example, papers, plastics, garbage, human waste, septic tank sludge, selected branches, etc., which are general wastes.
In the solid organic waste treatment process, organic waste such as garbage and plastic, which are solid organic waste, is supplied into the reaction vessel, saturated steam is introduced into the reaction vessel, and operating conditions: Normal temperature ~ 235 ° C, normal pressure ~ 3MPa, temperature rise and pressure increase time 1 ~ 3 hours, maximum temperature pressure holding time 5 minutes or more, let subcritical reaction (hydrothermal reaction in subcritical state) and dry by steam indirect heating etc. Powderize.

一方、液状有機性廃棄物処理工程では、液状有機性廃棄物であるし尿、浄化槽汚泥、下水処理汚泥等を汚泥再生処理センター等の水処理施設において生物脱窒法等により水処理し、水処理施設から出る余剰汚泥等の処理汚泥を汚泥脱水処理して脱水汚泥もしくは乾燥汚泥を得る。   On the other hand, in the liquid organic waste treatment process, liquid organic waste such as human waste, septic tank sludge, sewage treatment sludge, etc. is treated with water by a biological denitrification method in a water treatment facility such as a sludge regeneration treatment center. The treated sludge such as excess sludge from the sludge is dehydrated to obtain dehydrated sludge or dried sludge.

そして、固形状有機性廃棄物処理工程の生産物の乾燥粉末材と液状有機性廃棄物処理工程の生産物の脱水汚泥もしくは乾燥汚泥とを混合し、再資源化材として助燃材、堆肥化材を生産して有効利用を図る。この混合後の水分は低位発熱量が例えば３５００ｋｃａｌ／ｋｇ以上となる混合比率とする。   Then, the dry powder material of the product of the solid organic waste treatment process and the dehydrated sludge or the dried sludge of the product of the liquid organic waste treatment process are mixed, and the auxiliary combustor and composting material are recycled. For effective use. The moisture after mixing is set to a mixing ratio at which the lower heating value is, for example, 3500 kcal / kg or more.

亜臨界反応時に発生する蒸気含有成分は、汚泥再生処理センター等の水処理施設において有機栄養分（ＢＯＤ源）として有効に利用して処理する。このことにより、水処理施設において生物脱窒法で従来使用している炭素源の使用量が低減できる。   The steam-containing component generated during the subcritical reaction is effectively utilized as an organic nutrient (BOD source) in a water treatment facility such as a sludge regeneration treatment center. This can reduce the amount of carbon sources that are conventionally used in biological denitrification methods in water treatment facilities.

なお、上記方法は、家畜ふん尿水処理施設と固形状敷ワラ、オガクズ含家畜糞にも同様に適用できる。   In addition, the said method is applicable similarly to livestock excrement water processing facilities, solid bedding straw, and sawdust-containing livestock droppings.

以上のように本発明によれば、コンビニエンスストア、スーパーマーケット等からプラスチック、紙等を伴った生ごみ、食品廃棄物を分別せずに、亜臨界状態で分解して無菌化、乾燥粉末化させるので、プラスチック類の発熱量を有効に利用できる。また、製品となる再資源化材は原料に近い高発熱量を持ち、衛生的で取り扱い容易な粉末となり、亜臨界反応で水蒸気処理されているので、セミ賦活化（活性炭は完全賦活化されて活性が出る）されており、炭素主体の多孔質物性になっている。   As described above, according to the present invention, since garbage, food waste accompanied by plastic, paper, etc. from convenience stores, supermarkets, etc. are not separated, they are decomposed in a subcritical state to be sterilized and dried into powder. In addition, the calorific value of plastics can be used effectively. In addition, the recycled material used as the product has a high calorific value close to that of the raw material, becomes a hygienic and easy-to-handle powder, and is treated with steam by a subcritical reaction, so it is semi-activated (the activated carbon is fully activated) Active) and has a carbon-based porous property.

一方、し尿等の一般廃棄物は、汚泥再生処理センター等において汚泥の再資源化が行われているが、発熱量が低く、利用が進んでいない状況にあり、脱水汚泥又は乾燥汚泥は粘性が非常に高いものである。   On the other hand, general waste such as human waste is recycled as sludge at sludge recycling treatment centers, etc., but the amount of heat generation is low and the use is not progressing, and dehydrated sludge or dried sludge is viscous. It is very expensive.

このため、脱水汚泥又は乾燥汚泥を高カロリーの助燃材とするうえで、乾燥粉末材の高カロリー性と多孔質による通気性が有効に作用し、乾燥粉末材の混合により低位発熱量３５００ｋｃａｌ／ｋｇ以上とすることにより、再資源化原料として加熱等の必要がない原料となる。また、助燃材化等の目的に応じてペレット化も行う。   For this reason, when dehydrated sludge or dried sludge is used as a high-calorie auxiliary material, the high-calorie property of the dry powder material and the air permeability due to the porous material are effective, and the lower heating value is 3500 kcal / kg by mixing the dry powder material. By setting it as the above, it becomes a raw material which does not need a heating etc. as a recycling raw material. Moreover, pelletization is also performed according to the purpose such as making a support material.

以下、本発明の実施の形態を図面に基づいて説明する。固形状有機性廃棄物処理工程を行う亜臨界反応容器１は、外套容器２と外套容器２の内部に格納した反応容器３とからなる二重構造をなす。反応容器３の内部には攪拌羽根４を配置しており、攪拌羽根４の回転軸５は外套容器２の外部において正転、逆転可能なモータ６に接続している。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. The subcritical reaction vessel 1 for performing the solid organic waste treatment step has a double structure including an outer vessel 2 and a reaction vessel 3 stored in the outer vessel 2. A stirring blade 4 is disposed inside the reaction vessel 3, and a rotating shaft 5 of the stirring blade 4 is connected to a motor 6 that can be rotated forward and reversely outside the outer casing 2.

反応容器３は、固形状有機性廃棄物である生ごみ、プラスチック等を原料として投入する投入口７と、生産物である乾燥粉末材を取り出す取出口８と、排蒸気および排ガスの排出口９と、飽和水蒸気を供給する第１蒸気供給口１０を備えている。また、外套容器２は、飽和水蒸気を供給する第２蒸気供給口１１を備えており、第１蒸気供給口１０および第２蒸気供給口１１が飽和蒸気供給源１３に接続している。   The reaction vessel 3 includes an inlet 7 through which raw organic waste such as garbage, plastics and the like are input, an outlet 8 through which a dry powder material as a product is taken out, and an outlet 9 for exhaust steam and exhaust gas. And a first steam supply port 10 for supplying saturated steam. In addition, the outer container 2 includes a second steam supply port 11 that supplies saturated steam, and the first steam supply port 10 and the second steam supply port 11 are connected to a saturated steam supply source 13.

亜臨界反応容器１では、固形状有機性廃棄物である生ごみ、プラスチック等の有機性廃棄物を原料として投入口７から反応容器３内に投入し、第１蒸気供給口１０から反応容器３に飽和水蒸気を供給する。反応容器３の内部ではモータ６で回転駆動する攪拌羽根４が原料を高温高圧下で攪拌しながら取出口８へ向けて移送する。   In the subcritical reaction vessel 1, organic waste such as garbage and plastic, which are solid organic waste, is introduced as a raw material into the reaction vessel 3 from the introduction port 7, and from the first steam supply port 10 to the reaction vessel 3. Is supplied with saturated water vapor. Inside the reaction vessel 3, the stirring blade 4 that is rotationally driven by the motor 6 transfers the raw material toward the outlet 8 while stirring the raw material at high temperature and high pressure.

反応容器３の内部では、運転条件：常温〜２３５℃、常圧〜３ＭＰａ、昇温昇圧時間１〜３時間、最大温度圧力保持時間５分以上で亜臨界反応（亜臨界状態での水熱反応）させて、蒸気間接加熱等により乾燥粉末化させる。このとき、第２蒸気供給口１１から外套容器２に供給する飽和水蒸気により反応容器３が所定温度以上に保たれる。   Inside the reaction vessel 3, operating conditions: normal temperature to 235 ° C., normal pressure to 3 MPa, temperature increase / pressure increase time 1 to 3 hours, maximum temperature and pressure holding time 5 minutes or more, subcritical reaction (hydrothermal reaction in subcritical state) To dry powder by indirect steam heating or the like. At this time, the reaction vessel 3 is maintained at a predetermined temperature or higher by the saturated steam supplied from the second vapor supply port 11 to the mantle vessel 2.

生産した乾燥粉末材１４は取出口８から外部へ取り出し、排蒸気および排ガス１５は排出口９から外部へ取り出す。この乾燥粉末材１４は原料に近い高発熱量を持ち、衛生的で取り扱い容易な粉末であり、亜臨界反応で水蒸気処理されているので、セミ賦活化（活性炭は完全賦活化されて活性が出る）されており、炭素主体の多孔質物性になっている。   The produced dry powder material 14 is taken out from the outlet 8 and the exhaust steam and the exhaust gas 15 are taken out from the outlet 9 to the outside. This dry powder material 14 has a high calorific value close to that of the raw material, is a hygienic and easy-to-handle powder, and is steam-treated by a subcritical reaction, so that it is semi-activated (activated carbon is fully activated and activated) ) And has a carbon-based porous physical property.

一方、固形状有機性廃棄物処理工程は、汚泥処理センター等の水処理施設１６において行い、液状有機性廃棄物であるし尿、浄化槽汚泥、下水処理汚泥等を水処理施設１６で水処理し、生じる余剰汚泥を汚泥脱水処理（又は乾燥）１７する。   On the other hand, the solid organic waste treatment process is performed in a water treatment facility 16 such as a sludge treatment center, and liquid organic waste such as human waste, septic tank sludge, sewage treatment sludge and the like is treated with water in the water treatment facility 16. The resulting excess sludge is subjected to sludge dewatering treatment (or drying) 17.

液状有機性廃棄物処理工程の生産物である脱水汚泥もしくは乾燥汚泥１８は、固形状有機性廃棄物処理工程の生産物である乾燥粉末材１４と混合して再資源化材となし、助燃材１９、堆肥化材２０を生産して有効利用を図る。   The dehydrated sludge or dried sludge 18 that is the product of the liquid organic waste treatment process is mixed with the dry powder material 14 that is the product of the solid organic waste treatment process to form a recycling material, and an auxiliary combustion material. 19. The composting material 20 is produced and used effectively.

この際に、脱水汚泥（乾燥汚泥）１８は粘性が非常に高いものであるが、この脱水汚泥又は乾燥汚泥を高カロリーの助燃材とするうえで、乾燥粉末材１４の高カロリー性と多孔質による通気性が有効に作用し、乾燥粉末材１４の混合により低位発熱量３５００ｋｃａｌ／ｋｇ以上とすることにより、再資源化原料として加熱等の必要がない原料となる。また、助燃材化等の目的に応じてペレット化も行うこともできる。   At this time, the dehydrated sludge (dried sludge) 18 has a very high viscosity. When the dehydrated sludge or the dried sludge is used as a high-calorie auxiliary material, the high-caloric property and the porous property of the dry powder material 14 are obtained. The air permeability due to the water acts effectively, and by making the lower calorific value 3500 kcal / kg or more by mixing the dry powder material 14, it becomes a raw material that does not require heating as a recycled raw material. Moreover, pelletization can also be performed according to the objectives, such as auxiliary combustion material formation.

乾燥粉末材１４は原料となる一般廃棄物によっては成分が変動するが、表１に示すように、概ね低位発熱量３５００ｋｃａｌ／ｋｇを有している。したがって、乾燥粉末材１４の混合により低位発熱量３５００ｋｃａｌ／ｋｇ以上となる再資源化原料が得られる。   Although the components of the dry powder material 14 vary depending on the general waste as a raw material, as shown in Table 1, the dry powder material 14 generally has a lower heating value of 3500 kcal / kg. Accordingly, a recycled raw material having a lower heating value of 3500 kcal / kg or more can be obtained by mixing the dry powder material 14.
