【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、使用済農薬の廃液処理方法に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a method for treating waste liquid of used agricultural chemicals.
近年の世界的な人口増加にともない、効率よく食糧資源
を生産する上で、農薬の果たす役割は益々重要になりつ

かしなから、使用済み農薬の廃棄方法については、それ
ほと注意か払われていないのか現状である。With the recent increase in global population, the role played by pesticides is becoming increasingly important in efficiently producing food resources.At the same time, there are concerns about the safety of pesticides for users,
The impact on the environment is becoming a problem. For this,
A variety of medicinal plants, dosage forms, and application methods have been developed from the viewpoint of farmers who use the drug safely and easily. However, at present, little attention is being paid to how to dispose of used agricultural chemicals.
通常農薬製剤は1000〜3000倍の範囲で水に希釈
され、はぼ全量を散布するように調合されるか、残液が
残る場合も多々あり、また浸漬処理法による種子消毒の
場合は、残液か残る場合か多い。Pesticide formulations are usually diluted with water in a range of 1,000 to 3,000 times, and are mixed so that almost the entire amount is sprayed, or there are many cases where a residual solution remains. There are many cases where some liquid remains.
近年、環境問題か大きくとり上げられている中で、残っ
た希釈液中の農薬原体を完全に取り除き、希釈用に用い
た水をきれいにすると共に、水中に乳化あるいは溶解し
ている農薬原体を、焼却処理できるようにする必要かあ
る。In recent years, environmental issues have become a hot topic, and in addition to completely removing the active ingredients in the remaining diluent and cleaning the water used for dilution, it is necessary to remove the active ingredients that have been emulsified or dissolved in the water. Is there a need to make it possible to incinerate it?
本発明者等は、これらの問題を解決するため、鋭意検討

薬原体を含まず、臭いのない水を再生することか可能と
なることを見いだし本発明を完成した。In order to solve these problems, the present inventors conducted intensive studies and found that the agricultural chemical active ingredient emulsified or dissolved in a diluted liquid is first adsorbed on activated carbon, and then coagulated using an organic or inorganic coagulant. By doing so, the inventors have discovered that it is possible to regenerate odorless water with almost no pesticide ingredients in the supernatant liquid, and have completed the present invention.
即ち、本発明は水中に乳化あるいは溶解している農薬原
体をまず活性炭に吸着後、有機または無機の凝集剤を使
用して凝集させることにより農薬原体の含有量の少ない
水を再生する廃液の処理方法である。That is, the present invention is a waste liquid that regenerates water with a low content of agricultural chemical ingredients by first adsorbing the agricultural chemical ingredients that have been emulsified or dissolved in water onto activated carbon and then coagulating them using an organic or inorganic flocculant. This is the processing method.

現場で使用する場合は、かくはん装置かないことか多い
ため、手動でかくはんしても差し支えない。Regarding the amount of activated carbon used, it is important to note that if there is a large amount, it will be able to adsorb the pesticide active ingredient efficiently and in a short period of time; if it is too small, the adsorption efficiency will be poor, which is undesirable. Good. In addition, as for the method of adsorption, it can be completed in a short time by mixing well with dilution water, adding a large amount of activated carbon, or it can be completed within a few minutes by using a regular stirrer. do. However, when used on-site by farmers, there is often no stirring equipment available, so stirring manually is fine.

経過後も活性炭の分離は困難であった。Comparative Example-1 The same treatment as in Example-1 was performed until activated carbon was added and stirred, and then the solution was left to stand without adding sodium polyacrylate. Activated carbon was suspended in the residual liquid, and after a few days passed. However, separation of activated carbon was difficult.
