〔産業上の利用分野〕
本発明は、廃水をプラスチックにより固化する方法に関
するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for solidifying wastewater with plastic.
有害’ｓ質を含む産業廃棄物の貯蔵に当たっては逸散防
止、漏洩防止の観点から、液体または粉体の形態で保管

慮して放射性廃棄物の固化の手段としてセメント固化、
アスファルト固化、プラスチック固化のいずれかの方法
が実施されている。When storing industrial waste containing hazardous substances, it is not preferable to store it in liquid or powder form from the viewpoint of preventing dissipation and leakage. Considering this point, nuclear power plants use cement solidification as a means of solidifying radioactive waste.
Either asphalt solidification or plastic solidification is used.

廃棄物量の増大を招く問題点があった。このため、従来
プラスチック固化法が産業廃液の処理用に適用されたの
は、放射性廃液のような特殊な廃液に対してだけであっ
た。Among these methods, there is a method of solidifying waste liquid into plastic by adding and mixing a thermosetting resin that forms a water-in-oil emulsion to the waste liquid, emulsifying it, and then hardening it. In order to maintain the stability of the wastewater, the amount of thermosetting resin used as a solidifying agent must be reduced by 17%.
2 or more, and as a result, there was a problem in that the amount of solidified waste liquid, that is, the amount of waste, increased. For this reason, conventional plastic solidification methods have only been applied to special waste liquids such as radioactive waste liquids.
本発明は、従来方法の上記問題点に鑑みてなされたもの
で、廃水を固化するためのプラスチック固化処理方法に
おいて、固化剤の使用量を低下する（換言すれば、廃水

を提供することを目的とするものである。The present invention has been made in view of the above-mentioned problems of conventional methods, and reduces the amount of solidifying agent used (in other words, the ratio of wastewater/solidifying agent) in a plastic solidifying treatment method for solidifying wastewater. The purpose of the present invention is to provide an effective method that can reduce the cost of solidification treatment and reduce the amount of waste disposal.
本発明は、廃水を高吸水性ポリマーと混合して包摂し、

ック固化処理方法である。The present invention incorporates wastewater by mixing it with a superabsorbent polymer,
A wastewater plastic solidification treatment characterized by mixing the inclusions with a thermosetting resin or surrounding the inclusions with a thermosetting resin, and then curing the thermosetting resin at room temperature or under heating. It's a method.

とはない。The solidified product obtained by the present invention maintains a form in which wastewater is captured by a superabsorbent polymer and the captured water (inclusions) is encapsulated in a thermosetting resin coating material. To give an example, the water-captured material is similar to agar, and the solidified material is shaped like agar wrapped in splashed pattern and then made into hard mochi (rice cake with splashed pattern). Therefore, the solidified water will not flow out or ooze out even if the solidified material is compressed and deformed or cut to expose the water-captured material.
本発明によれば、後記する実施例から明らかなように、
簡便な方法で廃水の固化処理が行なえ、廃水／固化剤の

ム缶で処理するときの従来法との比較を示すと下表のと
おりである。According to the present invention, as is clear from the examples described later,
Solidification treatment of wastewater can be carried out using a simple method, and the ratio of wastewater/solidification agent can be easily reduced to 3:1 from the conventional 2:1 at most.
The above can be achieved, and therefore the amount of thermosetting resin used can be significantly reduced. That is, the table below shows a comparison with the conventional method when processing 2001 drums.
上表から分かるように１本のドラム缶発生当たり、固化
剤消費量は本発明では従来法の５５％であり、廃水処理

しても適用可能となるものである。As can be seen from the above table, the amount of solidifying agent consumed per drum generated by the present invention is 55% of the conventional method, and the amount of wastewater treated is 136% of the conventional method, meaning that wastewater treatment using the plastic solidifying method is only for radioactive wastewater. It can also be applied to general industrial wastewater.
