The present invention relates to a waste disposal device comprising: a body surrounded by a first partition member, wherein the interior of the seat is separated into a separate processing space and a collection space by using a second partition. The seat body is provided with a waste input passage and a liquid fertilizer collecting passage respectively penetrated into the processing space, and the base body is further provided with an input end and an output end respectively extending to the collection space； a shielding member is fixed on the collection space The shielding member is provided with a notch, and the periphery of the notch is bent downward to provide a blocking portion, and the blocking portion is spaced apart from the second separating member； a protective net shields the processing space. It can be used to raise black pupa larvae, and use black squid larvae to decompose waste materials such as animal waste, kitchen waste or organic biological waste.本創作係關於一種廢棄物處理裝置，包含：一座體，由一第一分隔件所圍繞而成，該座體內部利用一第二分隔件而區隔成獨立之一處理空間及一收集空間，該座體設有一廢料投入通道及一液肥收集通道分別貫通至該處理空間內，又該座體另設有一輸入端及一輸出端分別貫通至該收集空間；一遮蔽件固定於該收集空間上，該遮蔽件設有一缺口，該缺口的周緣係向下彎設有一阻擋部，該阻擋部係與該第二分隔件之間保持一間距；一防護網遮蔽該處理空間。藉以可供飼養黑水虻幼蟲，並利用黑水虻幼蟲大量分解畜牧動物之糞便、廚餘或有機生物廢料等廢棄物。
