This paper expounds the design background,construction,experimental environment and teaching effect of the virtual simulation experiment system of sludge treatment and resource utilization.A virtual simulation module was established for aerobic fermentation and dehydration incineration process.The student operation is divided into four parts:constructing process route,designing calcula-tion,running and debugging simulation experiment,and submitting operation.Virtual simulation exper-iment can make students familiar with the basic knowledge,main equipment and process flow of aerobic fermentation and dehydration incineration process,and make up for the deficiency of physical experi-ment.
