Description

本発明は、廃棄物処理設備に収集された廃棄物のうち、有機質系廃棄物（バイオマス）の乾留により生成された可燃性ガスを利用して、廃棄物処理設備から生じて処理されるべき被処理水をこの廃棄物処理設備のための用水として利用できるようにした廃棄物処理設備における被処理水利用装置に関するものである。   The present invention uses the combustible gas generated by dry distillation of organic waste (biomass) among the waste collected in the waste treatment facility, and generates the waste to be treated from the waste treatment facility. The present invention relates to an apparatus for using water to be treated in a waste treatment facility that can use treated water as water for the waste treatment facility.

廃棄物処理設備には、従来、下記特許文献１に示されるものがある。この公報のものによれば、上記有機質系廃棄物である木質資源を乾留して可燃性ガスと炭化物とを生成する乾留装置と、上記可燃性ガスの燃焼熱により蒸気を生成し、この蒸気により発電をする発電装置とが設けられている。   Conventionally, there is a waste treatment facility disclosed in Patent Document 1 below. According to this publication, a carbonization device for carbonizing the wood resources as the organic waste to produce combustible gas and carbide, and steam generated by the combustion heat of the combustible gas, And a power generation device for generating power.

つまり、上記廃棄物処理設備によれば、廃棄物である木質資源が有効利用されて、発電装置により電力が得られるようになっている。
２００４−２３９１６２号公報 That is, according to the waste treatment facility, wood resources that are waste are effectively used, and electric power can be obtained by the power generation device.
2004-239162

ところで、一般に、廃棄物処理設備における最終処分場では、広大な土地に大きく拡がる露天状の凹所が構築される。この凹所の底面に遮水シートが敷設され、この凹所内に廃棄物が貯留されるようになっている。この場合、上記凹所の底部には、主に雨水である多量の水が自然発生的に溜まることとなって好ましくない。そこで、従来、上記水は、処理されるべき水、つまり被処理水として、活性汚泥法などの水処理装置によって浄化され、かつ、活性炭による水処理装置によって濾過された後、清水として一般河川などに放流されている。   By the way, in general, in the final disposal site in the waste treatment facility, an open-pit-like recess that extends greatly over a vast land is constructed. A water shielding sheet is laid on the bottom surface of the recess, and waste is stored in the recess. In this case, a large amount of water, which is mainly rainwater, naturally accumulates at the bottom of the recess, which is not preferable. Therefore, conventionally, the above-mentioned water is purified as a water to be treated, that is, treated water by a water treatment device such as an activated sludge method, and after being filtered by a water treatment device using activated carbon, as a fresh water as a general river. Has been released.

一方、上記廃棄物処理設備では、焼却炉や焙焼炉の冷却用などとして多量の用水が使用されるが、これら用水は、主に地下水を汲み上げることにより調達されている。   On the other hand, in the waste treatment facility, a large amount of water is used for cooling an incinerator or a roasting furnace, and these waters are procured mainly by pumping up ground water.

On the other hand, in the above waste treatment facility, although a large amount of water is procured mainly by pumping up groundwater, the treated water generated from this waste treatment facility is not used at all and is complicated. It is discharged to the outside of the waste treatment facility through the water treatment work. For this reason, there is room for improvement in using the water to be treated more effectively in the waste treatment facility.
