Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、循環式トイレ処理剤に係わり、さらに詳しく
は、抗細菌剤と抗黴剤とを含有する循環式トイレ処理剤
に関する。TECHNICAL FIELD The present invention relates to a circulating toilet treating agent, and more particularly to a circulating toilet treating agent containing an antibacterial agent and an antifungal agent.
本発明の循環式トイレ処理剤は、洗浄水を循環使用する
列車、バス、航空機、船舶等のトイレ脱臭処理用として
好適である。INDUSTRIAL APPLICABILITY The circulating toilet treating agent of the present invention is suitable for toilet deodorizing treatment of trains, buses, airplanes, ships, etc. that circulate and use wash water.
一般的なし尿から発生する悪臭の脱臭法として、 （１） 芳香剤によるマスキング法、 （２） 悪臭物質との化学反応により悪臭を除去する化
学脱臭法、 （３） 吸着剤により悪臭を除去する物理脱臭法、 （４） 微生物により悪臭を分解する生物脱臭法、 など、およびこれ等を組み合わせた方法が、従来から採
用されている。As a deodorization method for general malodor generated from human waste, (1) masking method with aromatic agent, (2) chemical deodorization method to remove malodor by chemical reaction with malodorous substance, (3) removal of malodor with adsorbent A physical deodorization method, (4) a biological deodorization method in which a malodor is decomposed by microorganisms, and a method combining these methods have been conventionally used.
一方、列車、バス、航空機、船舶等に使用される洗浄水
循環式トイレから発生する悪臭物質は、硫化水素等の硫
黄化合物とアンモニアとを主成分としている。これら
は、循環水中のし尿から発生するものであり、排泄時に
し尿中に含まれるものと、排泄後バクテリア等の微生物
によるし尿の腐敗分解により発生するものとがあり、後
者が前者に比べて圧倒的に多い。On the other hand, a malodorous substance generated from a wash water circulation type toilet used in a train, a bus, an aircraft, a ship, etc. is composed mainly of a sulfur compound such as hydrogen sulfide and ammonia. These are generated from human waste in circulating water, and some are contained in human waste at the time of excretion, and some are generated by putrefaction decomposition of human waste after being excreted by microorganisms such as bacteria. There are many.
これらの悪臭の脱臭方法としては、マスキング法は、悪
臭の発生量が多い場合マスキング効果が不十分となり、
香料との混合臭がかえって不快感を与えることがある。
化学脱臭法は、循環水中でのし尿の滞留時間に対応して
化学脱臭剤を使用する必要があり、長時間し尿が滞留す
る場合には、多量の脱臭剤を必要とする。物理脱臭法
は、吸着設備の設置が必要であり、マスキングを目的と
した芳香剤も吸着除去されるため、香料との併用ができ
ない。生物脱臭法では、無臭化に長時間を要し、温度が
低いと殆ど効果がなくなる。したがって、これらの方法
を循環式トイレの脱臭方法として採用することは容易で
はない。As a deodorizing method for these malodors, the masking method has an insufficient masking effect when a large amount of malodor is generated,
The mixed odor with a fragrance may give an unpleasant feeling.
In the chemical deodorization method, it is necessary to use a chemical deodorant in accordance with the retention time of night soil in circulating water, and when long night soil is retained, a large amount of deodorant is required. The physical deodorization method requires the installation of adsorption equipment, and the fragrance for the purpose of masking is also adsorbed and removed, so that it cannot be used in combination with a fragrance. In the biological deodorization method, it takes a long time to deodorize, and it is almost ineffective when the temperature is low. Therefore, it is not easy to adopt these methods as the deodorizing method for the circulation type toilet.
循環式トイレを使用しているJR各社のトイレの脱臭に
は、従来トリクロルイソシアヌル酸を主剤とする処理剤
が使用されてきたが、トリクロルイソシアヌル酸を主剤
とする製剤の使用は、循環水への着色剤の使用ができな
いため、し尿色で着色した洗浄水が循環し、利用者に不
快感を与える。To deodorize the toilets of JR companies that use circulating toilets, a treatment agent containing trichloroisocyanuric acid as the main ingredient has been used in the past, but the use of a formulation containing trichloroisocyanuric acid as the main ingredient Since the coloring agent cannot be used, the wash water colored with night soil circulates, which causes the user discomfort.
また、これらの循環水を外部で活性汚泥処理する場合
に、残留した脱臭剤が、活性汚泥に悪影響を及ぼす。Further, when these circulating waters are treated with activated sludge outside, the residual deodorant adversely affects the activated sludge.
上記から、JR各社ではトリクロルイソシアヌル酸を主剤

いる。抗細菌剤を主剤とする製剤は、脱臭効果に優れ、
循環水への着色が可能なこと、また、過剰に使用しない
限り活性汚泥処理への影響を殆どないことから、循環式
トイレ処理剤としては、極めて良好な処理剤である。し
かしながら、この処理剤を、長時間列車トイレで使用す
ると、循環水の排水管や循環ポンプのフィルター部に、
黴（糸状菌）が多量に増殖して寒天状のスライムが発生
し、排水管やフィルターに詰まりが生ずることがある。From the above, each JR company has stopped using a treatment agent containing trichloroisocyanuric acid as a main ingredient and has switched to a treatment agent containing an antibacterial agent as a main ingredient.
A formulation containing -bromo-2-nitropropane-1,3-diol was proposed (see Japanese Patent Application No. 63-308860 and Japanese Patent Application No. 63-324153) and supplied to each JR company. ing. Formulations based on antibacterial agents have excellent deodorizing effects,
Since it is possible to color circulating water and has almost no effect on the treatment of activated sludge unless it is used excessively, it is a very good treatment agent as a circulating toilet treatment agent. However, if this treatment agent is used in a train toilet for a long time, it will become
A large amount of mold (filamentous fungus) grows to generate agar-like slime, which may cause clogging of drainage pipes and filters.
