Abstract
Description
(混合工程)
混合工程は、ミミズの糞土と水とを混合する工程である。
回収工程では、混合工程で得られた混合物から生じる気化した水を回収して液体(以下、「有機物分解水」とも称する)を得る工程である。混合工程を行いながら、回収工程を行ってもよい。
気化した水を回収工程で回収して得られる有機物分解水をそのまま消臭剤として用いることもできるが、希釈して用いることが好ましい。希釈に用いる溶媒としては、水を用いればよく、水道水や蒸留水を用いることができる。また、希釈に用いる水は、濾材、逆浸透膜等を用いて浄水処理されていてもよい。バクテリア等の微生物の除去の観点から、微細孔の濾材や逆浸透膜等を用いることが好ましく、例えばSPG(シラス多孔質ガラス)透過膜を用いることが好ましい。
本発明の消臭剤は、本発明の消臭剤の製造方法で得られることを特徴とするものである。本発明の消臭剤は、本発明の消臭剤の製造方法で得られる消臭効果を奏する液体を用いたものであれば特に限定されないが、液状であることが好ましい。また、前記消臭作用を有する液体に、例えば賦形剤等を混合して、ゲル状、粉状、粒状等の固形に加工されたものであってもよい。
アカミミズの糞土40kgを入れた槽(以下、「反応槽」と呼称する)に、水40Lを加えて、攪拌しながら、気化した水を反応槽に取り付けた除湿機(ナカトミ社製、DM-30)で約1日かけて回収し、15~20Lの液体を得た。反応槽にさらに水を10~20L加水して、気化した水を同様に除湿機で約1日かけて回収し、15~20Lの液体を得た。得られた液体を混合した40L程度の液体(pH6.8)を実施例1の消臭剤として用いた。
アカミミズの糞土40kgと木材15kg(木材チップ5kgとノコクズやモミガラのブレンド10kg)を入れた反応槽に、水40Lを加えて、攪拌しながら、気化した水を反応槽に取り付けた除湿機(ナカトミ社製、DM-30)で約1日かけて回収し、15~20Lの液体を得た。反応槽にさらに水を10~20L加水し、木材10kg(木材チップ5kgとノコクズやモミガラのブレンド5kg)て、気化した水を同様に除湿機で約1日かけて回収し、15~20Lの液体を得た。得られた液体を混合した40L程度の液体(pH8.71)を実施例2の消臭剤として得た。
アカミミズの糞土40kgと菌床5kgと木材15kg(木材チップ5kgとノコクズやモミガラのブレンド10kg)を入れた反応槽に、水40Lを加えて、攪拌しながら、気化した水を反応槽に取り付けた除湿機(ナカトミ社製、DM-30)で約1日かけて回収し、回収した15~20Lの液体(pH8.27)を実施例3の消臭剤として得た。
アカミミズの糞土40kgと菌床5kgと木材15kg(木材チップ5kgとノコクズやモミガラのブレンド10kg)を入れた反応槽に、水40Lを加えて、攪拌しながら、1日経過させた後に、気化した水を反応槽に取り付けた除湿機(ナカトミ社製、DM-30)で約1日かけて回収し、回収した15~20Lの液体(pH7.78)を実施例4の消臭剤として得た。
実施例1~4の消臭剤をそれぞれ、水で5倍に希釈した液体を実施例5~8の消臭剤として得た。
15mLの遠沈管に、各実施例の消臭剤を1.8mLと、ニオイの発生源として11%アンモニア水0.2mL又は比較対象として蒸留水0.2mLを添加して攪拌した後、30℃で保温し、2時間後及び4時間後の気相の臭いをニオイセンサXP329-IIIR(新コスモス電機社製)で測定した。また、比較試験として、消臭剤を水に変えて同様に臭いを測定した(比較例1)。臭いの測定値の算出方法は、アンモニア水添加のニオイ値から蒸留水添加のニオイ値を引いて、さらに測定場所の空間のニオイ値を引いて算出した。水を用いた比較試験(比較例1)のニオイ値を100%としたニオイレベルで比較した。100%を下回れば、消臭されていることを示す。結果を表1及び図1、2に示す。
