快速堆肥化裝置之研製
Manufacture of Rapid-Composting Device
摘要
快速堆肥化裝置之研製旨在解決農民、學校及家庭等利用廚餘、落葉製作堆肥產生臭味問題。本裝置係採用好氣發酵及保溫原理設計，其架構包括容置桶、隔絕網架、通氣裝置及進氣設備四大部份，可確保堆肥化過程進行好氣發酵，好氣微生物分解有機物質產生熱量，藉雙層保溫裝置使堆肥體熱量累積，溫度高達60－70℃日數維持長達5天以上，可將病原菌、蟲卵及雜草種子等殺滅，且不會產生臭味，堆積發酵時間僅需25－30天即可完成，並可同時進行堆肥廢液氧化發酵，作為有機液體肥料之用。堆積發酵完成之堆肥添加50％土壤（體積比），播種小白菜及薙菜種子不影響其發芽率。本裝置具快速發酵及環保特性，商品化後可廣泛適用於農戶、學校教育團體、社區、家庭及市民農園利用落葉、廚餘、雜草等有機廢棄物製作堆肥。

The stinking smell is often generated from making compost using kitchen and farm wastes. In order to solve this problem, a rapid composting device, consisting of a compost container, net support, and exhausting and aeration system was designed, this device ensured aerobic fermentation and the generation of heat from decomposition of organic matters by aerobes in the composting process. The compost container enclosed with double wall could cumulate and keep heat in the composting materials, which made temperature rising up to 60-70°C for more than 5 days and killed pathogens, insect eggs, and weed seeds. It took only 25-30 days to complete the composting process. No stinking smell was detected. The waste liquid collected from waste water outlet could be used as liquid organic fertilizer. Results of seed germination test in Pak-choi and water convolvulus, using composts prepared by rapid composting device and mixed with 50 % soil in volume as germination media, indicated that the percent germination was not significantly influenced by various composts. This new device for rapid composting would be of use for farmers, school, community and family etc. in making compost.
