Description

本発明は、廃棄物の分別方法に関し、特に、含水率の高い土砂を含む大量の瓦礫等の含水した電荷を有する粒子及び異物を含む廃棄物の分別方法に関するものである。   The present invention relates to a method for separating waste, and more particularly, to a method for separating waste containing particles having a water content such as a large amount of rubble containing earth and sand having a high water content and foreign matters.

従来、震災時に大量に発生する瓦礫は、被災地で発生した瓦礫を、集積地に集め、可燃物、不燃物等の分別作業が行った後、処理施設に搬出し、必要に応じて、破砕処理を行い、環境創造用資材、リサイクル製品、埋立資材等に有効利用するととともに、有効利用できないものは、必要に応じて、焼却処理された後、管理型処分場等で処理するようにしている。   Conventionally, a large amount of debris generated during an earthquake disaster is collected in an agglomerated area, separated from combustible and incombustible materials, and then transported to a treatment facility. We perform crushing treatment and use effectively for environmental creation material, recycling product, landfill material, and thing which cannot be used effectively should be incinerated if necessary, and then processed at a managed disposal site etc. Yes.

ところで、上記瓦礫の処理方法として、都市型の街区におけるビルの破壊跡等から発生するいわゆる瓦礫の処理方法として、例えば、特許文献1に開示されたような方法が提案されている。   By the way, as a method for treating the above-mentioned debris, for example, a method as disclosed in Patent Document 1 has been proposed as a method for treating so-called debris generated from building destruction marks in an urban block.

特開平9−75772号公報JP-A-9-77772

しかしながら、今回の東日本大震災のような津波を伴う震災時に発生した瓦礫は、含水率の高い土砂を大量に含むため、被災地からそのままの状態で瓦礫を集積地に搬送することは困難であり、また、特許文献1に開示された方法では、大量の処理水及びその後処理が必要になることから、インフラストラクチャーが壊滅状態にある被災地では採用することが困難であった。   However, rubble generated during the tsunami such as the Great East Japan Earthquake contains a large amount of sediment with a high moisture content, so it is difficult to transport rubble as it is from the disaster area to the accumulation area. Moreover, since the method disclosed in Patent Document 1 requires a large amount of treated water and subsequent treatment, it has been difficult to employ in a disaster area where the infrastructure is in a devastated state.

一方、含水率の高い土砂を含む瓦礫の場合、これを加熱したり、含水率の高い土砂を含む瓦礫に生石灰等の改質剤を添加することによって、含水率を低下させた後、篩い分けを行うことにより瓦礫から土砂を分離し、該土砂を分離した瓦礫を、集積地や処理施設に搬出することも考えられるが、粉塵やアンモニア等の有害ガスが発生しやすく周囲の環境に悪影響を及ぼすおそれがあり、また、処理にエネルギや時間を要し、大量の瓦礫の処理には適さない等の問題があった。   On the other hand, in the case of rubble containing earth and sand with a high moisture content, the moisture content is reduced by heating this or adding a modifier such as quick lime to the rubble containing earth and sand with a high moisture content, followed by sieving It may be possible to separate the earth and sand from the debris and transport the separated debris to an accumulation area or treatment facility.However, harmful gases such as dust and ammonia are likely to be generated and the surrounding environment is adversely affected. In addition, there is a problem that energy and time are required for the treatment, and it is not suitable for the treatment of a large amount of rubble.

また、上記の含水率の高い土砂を含む瓦礫以外でも、有害物質(PCB、VOC、重金属、農薬、油等)を含有する土砂等の電荷を有する粒子及び異物を含む廃棄物から異物を分別するための簡易な処理方法が要請されていた。   In addition to rubble containing earth and sand having a high water content, the foreign substances are separated from wastes containing particles and foreign substances having electric charge such as earth and sand containing harmful substances (PCB, VOC, heavy metals, agricultural chemicals, oil, etc.). Therefore, a simple processing method has been requested.

本発明は、上記の課題に鑑み、含水率の高い土砂を含む大量の瓦礫等の含水した電荷を有する粒子及び異物を含む廃棄物を、周囲の環境に悪影響を及ぼさず、また、処理にエネルギや時間を要することなく処理することができる廃棄物の分別方法を提供することを目的とする。   In view of the above-mentioned problems, the present invention does not adversely affect the surrounding environment and does not adversely affect the surrounding environment, and does not adversely affect the waste. Another object of the present invention is to provide a method for separating waste that can be processed without requiring time.

上記目的を達成するため、本発明の廃棄物の分別方法は、含水した電荷を有する粒子及び異物を含む廃棄物に、下記(A)〜(F)の物質のいずれか又は複数を添加、混練した後、篩い分けを行うことにより、前記廃棄物から篩目より大きな異物を分離することを特徴とする。

そして、本発明の廃棄物の分別方法は、含水率の高い土砂を含む瓦礫の処理の用途に好適に用いることができる。   And the waste separation method of this invention can be used suitably for the use of the debris containing earth and sand with a high moisture content.
