Abstract

A plurality of unit bags 2a, 2b . . . are composed of a permeable strip-shaped nonwoven and arranged in a successive fashion without break so that they can be easily accommodated and stored by being rolled. An annular elastic body 5 disposed around an opening 3a formed to an end of each bag 2a permits the opening 3a to be opened. Since an optically sensing object or a magnetically sensing object is disposed around the opening 3a or at a position spaced apart from the openings 3a, 3b . . . a prescribed distance, the portion of the sensing object can be positioned by a sensing device 15. Further, when, for example, sludge, and the like containing water are accommodated in a waste accommodating bag 1 and squeezed, the sludge, and the like can be easily dehydrated. With this arrangement, there can be provided a waste accommodating bag, a waste treatment system using the waste accommodating bag and a waste treatment apparatus capable of simply dehydrating water-containing wastes such as sludge in a sludge tank (including a pond, lagoon, and the like as the target of the present invention) and easily and economically disposing of the wastes as well as stably subjecting the sludge in a combined treatment tank to a biological treatment.
