<p><P>PROBLEM TO BE SOLVED: To provide a method of manufacturing compost in which hairs or the like contained in a sewage are not remained in a compost obtained from a sludge discharged after treating the sewage with an active sludge, and particles constituting the compost are not mutually combined by fibrous inclusions and independently treatable. <P>SOLUTION: The method is for manufacturing the sludge compost from a sludge generated accompanying an active sludge treatment of an organic drainage; the sludge contains fibrous inclusions; and the method is implemented through a process for concentrating the sludge, a process for removing the fibrous inclusions from the concentrated sludge by using a removing apparatus formed by combining a filter through which the fibrous inclusions are difficult to permeate and an impeller rotating at just before the filter, and a process for composting the sludge from which the fibrous inclusions are removed. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
