NOVELTY - Organic waste biological treatment management system, comprising a conversion unit converting the waste material information into discarding property data, based on waste material code which is obtained based on ejection person code, is new. A generation unit generates a taking over plan of organic waste based on comparison of the present processing situation and maximum tolerance of waste material acceptable in a treatment facility (11A,11B), and the discarding property data.    USE - For managing biological treatment such as methane fermentation processing and activated sludge treatment of organic waste.    ADVANTAGE - Steady and efficient operation management can be performed. The characteristic data is obtained easily by using waste material code and ejection person code, and the processing amount in the control center is decreased significantly.    DETAILED DESCRIPTION - Organic waste biological treatment management system, comprising a conversion unit converting the waste material information into discarding property data, based on waste material code which is obtained based on ejection person code, is new. A generation unit generates a taking over plan of organic waste based on comparison of the present processing situation and maximum tolerance of waste material acceptable in a treatment facility (11A,11B), and the discarding property data. The taking over plan is drawn by combining the methane activity measurement result showing the processing situation of the methane fermentation tank. A taking over plan is drawn so that the nitrogen concentration in the methane fermentation tank becomes below predetermined concentration, and ratio of carbon and nitrogen in aerator lies in predetermined range.    An INDEPENDENT CLAIM is included for organic waste biological treatment management method.    DESCRIPTION OF DRAWING(S) - The figure shows the network configuration of the organic waste biological treatment management system.
