| Summary: | 碩士 === 中華科技大學 === 健康科技研究所 === 103 === Family fruit and vegetable waste composting process and final bottled characteristics are variation, hence, this study selected our laboratory two species Streptomyces aureus (NP1) and Trichoderma sp., and nine different two commercial powders, to survey the composting of fruit and vegetable waste barrels test, also compare to their composting performance. From feed original material analysis, waste and sawdust moisture content of fruits and vegetables were 87.56 ± 0.10% and 8.76 ± 0.05%, dry ash were 7.94 ± 0.09% and 0.20 ± 0.01%, respectively. The total carbon were 4.11 ± 0.06% and 39.70 ± 0.18%, total nitrogen were 0.57 ± 0.03% and 0.31 ± 0.02%, the C/N ratios were 7.21 ± 0.26 and 128.01 ± 6.86. The results show that the first 35 days of moisture content between 64.13 ± 0.02%~73.24 ± 0.05%, ash content between 14.09 ± 0.09% ~ 19.18 ± 0.09%, the total carbon content between 6.84 ± 0.08%~7.44 ± 0.06%, total nitrogen content between 0.55 ± 0.03%~0.70 ± 0.01%, the temperature between 39℃~42℃, the germination rate between 68 ± 0%~88 ± 0%, and organic matter between 22.89 ± 0.07%~28.99 ± 0.05%, the C/N ratio ranged from 9.96±0.39~13.4±0.31, total phosphorus content between 0.67 ± 0.11% ~1.49 ± 0.08%, the water-soluble phosphorus content ranged from 0.48 ± 0.03%~0.72 ±0.01%, last pH value ranged from 6.94 ± 0.08~7.66 ± 0.04. The first fruits waste composting the first 35 days of the experimental, from the data showed that the total nitrogen content of 0.67% of the maximum was NO.8, and the other NO.2, NO.3 and NO.7 were 0.66%, 0.66% and 0.65% more higher than others. Total phosphorus content 1.49 % to the highest was NO.8, the other NO.3, NO.4 and NO.7 were 0.94%, 0.99% and 1.15%. The water-soluble phosphorus content 0.72% the highest was NO.2, and the other was NO.4 was 0.70% and NO.7 was 0.69%. from the data NO.4 organic matter content of 28.99% in the highest, NO.2, NO.3, and NO.8 were 27.00%, 27.10% and 26.78%. To survey the powder prices, house kitchen waste content more waters, it is possible to going anaerobic fermentation, also contains a variety of raw food waste. Therefore, more suitable for use NO.4 Qiao Kaiya kitchen compost kitchen waste, if the house kitchen can be classified, delete the difficult decomposition of raw food waste, and control the moisture content, it is suitable for use the lowest cost NO.3 Trichoderma TCT301 to be treated composting fruit and vegetable waste. It will still to find the optimum conditions for composting fruit and vegetable waste.
