Improvements in the Efficiency of Treatment Facilities for Municipal Solid Wastes (MSW)

Absrtact	The purpose of this project is to understand the efficiency of treatment plants for municipal solid waste (MSW), including kitchen waste pre-crushing treatment processes, high-efficiency fermentation facilities, washed equipments for MSWI fly ash, and mechanical treatment (MT) facilities. In order to evaluate the effectiveness of the facilities, there are several inspections tested in this project. Among them, evaluations of 12 pre-crushing treatment facilities has been completed, include quality testing analysis and effectiveness assessment. As the results, the dehydration rates of these facilities are from 0.13% to 27.71%, and moisture removal rates are from 0.5% to 77.5%. In the “high-efficiency composting facility” section, 9 facilities had been inspected according to the organic fertilizer testing for the products. Based on "Kinds, Items and Standards of Fertilizers", the test results indicated that the moisture contents of samples from 7 plants is slightly higher, and pH values and the germination percentage values of samples from 4 plants are lower than the standard. In addition, the analyses of TCLP, Dioxin, chloride, chlorine ion, potassium, sodium, and chemical contents of CNS 3036 in the samples of the fly ash were tested. The test results of the fly ash sample from Beitou Incineration Plant show that the concentration of Dioxin and furan in fly ash is higher than the standard value, 1.0 ng I-TEQ/g. It is not affected for reuse because of that the dioxin can be destroyed during the cement sintering process. Besides, the moisture content in the fly ash after washed presents much higher value according to be dehydrated by filter press after washing. Thus, it is better to be dried before reuse. Finally, through the MT processes in Yunlin MT Plant, the proportion of combustible waste increased from 38.2% to 49.6%, and the proportion of plastics after mechanical sorting increased from 32.9% to 59.6% based on the analysis of physical characteristic. It is useful to be classified to combustible and non-combustibles substances by the MT processes.
