Zusammenfassung:To predict a generation quantity of biogas by specifying a kind of treated waste.SOLUTION: A waste treatment system comprises: a receiving hopper H for receiving waste; a pretreatment part 1 into which the waste is supplied from the receiving hopper H and which executes pretreatment including crushing of the waste; a wet type methane fermentation tank 2 for generating biogas including methane gas by fermenting the pretreated waste; an imaging device C for imaging the waste supplied to the pretreatment part 1; and a management device 10 for analyzing an imaged image by the imaging device C, specifying the kind of waste based on a color, a concentration and an irregularity degree of the waste, and predicting a generation quantity of the methane gas or the biogas by using the specified kind and a waste input quantity to the wet type methane fermentation tank 2.SELECTED DRAWING: Figure 1 【課題】処理される廃棄物の種類を特定し、バイオガスの発生量を予測する。【解決手段】廃棄物処理システムは、廃棄物を受け入れる受入ホッパHと、受入ホッパHから前記廃棄物が供給され、前記廃棄物の破砕を含む前処理を行う前処理部1と、前記前処理された廃棄物を発酵させ、メタンガスを含むバイオガスを発生させる湿式メタン発酵槽2と、前処理部1に供給される廃棄物を撮影する撮影装置Cと、撮影装置Cによる撮影画像を解析し、前記廃棄物の色、濃度及び凹凸度に基づいて前記廃棄物の種類を特定し、特定した種類及び湿式メタン発酵槽2への廃棄物投入量を用いて前記メタンガス又は前記バイオガスの発生量を予測する管理装置10と、を備える。【選択図】図1
