Study on the Composition Characteristics of Incineration Treatment from MSW-A Case of TP City Kitchen Wastes

摘要

This study selected TP City A, B, and C incineration plant as sampling sites and each site samples three times. To understand the physical and chemical composition of TP municipal solid waste (MSW). We classified kitchen waste into 13 categories, and conducts a drying process on kitchen waste in order to determine its drying rate, water content, and drying time. According to the experiment result, we can evaluate and design the required space for solar drying equipment for kitchen waste. The composition of MSW in TP city is 39.1 wt% paper, 5.9 wt% fiber cloth, 3.5 wt% wood and straw, 19.3 wt% kitchen waste, 21.3 wt% plastic, and 3.0 wt% leather, and the average water content is about 35.9 wt%. For the kitchen waste, the three main categories were 37.4 wt% vegetables and fruits, 20.7 wt% peels, and 8.4 wt% noodles, and the average water content was 74.3 wt%. By conducting 6 to 7 hours of drying processing, the water content can be reduced by 34.2%～55.8%, and the drying rate is about 0.0031 -0.0002 g-H_2 G/g min. According to the experiment result, this study inference the area of the solar drying equipment is about 23 basketball courts of international standard specifications.
