| Abstract | In this thesis, innovative research and development of high efficiency kitchen waste collection bins to improve drain current traditional kitchen waste collection bins can not effectively drain excess water in addition to, Mainly for the New Taipei City Environmental Protection Bureau since 1 December 1999 the full implementation of new garbage collection after, The average daily volume of compost kitchen waste recycling increased to 260 tonnes explosion, Evaluation tests for draining rate, drain rate on the impact of food waste composting and compost finished three sections on seed germination and explore for composting food waste drain effect. During the experiment results of the analysis of traditional-style kitchen waste collection bins in the kitchen drain, the drain did not drain the obvious ability, kitchen waste moisture content had been maintained at 96% to about 98%. drain and efficient kitchen food waste collection bins can reduced the moisture content of about 70% to 75%, can effectively reduce the moisture content of food waste, food waste can be reduced by about 20% moisture content. Make compost kitchen waste moisture content before approaching the optimum moisture content of compost (about 65%), to reduce the compost fermentation time, solve the high moisture content of food waste composting fermentation leaving the problem for too long. The pH, moisture content, temperature, and carbon-nitrogen ratio of the compost comparative evaluation, the compost temperature changes and the consumption of carbon-nitrogen ratio, high efficiency kitchen waste collection bins in addition to draining the gravity method, also increased the semi-mechanical gravitational pressure, in the kitchen waste into compost quickly when thermophilic phase, thereby shortening the time to know composting. Speculated that about 35 to 40 days or so close to the finished compost, kitchen waste collection bins because of the traditional way of relying on gravity to remove the moisture content of food waste, although composting time was decreasing, but still about 45 ~ 50 genius has finished compost . After 60 days composting fermentation, germination test three days after the results are summarized, high-efficiency drain bucket drain and collect kitchen waste for composting fermentation and germination test, the germination rate of up to 98.7% (life and life than a kitchen and deciduous : 1). Evident by the high efficiency of food waste collection bins Drain Drain the kitchen after about 60 days compost composting been completed, presumably mainly due to the high efficiency drained by collecting food waste food waste bucket after draining moisture content (70% to 75 %) is close to the optimum moisture content of compost (65%), resulting in the compost when it has begun to enter the initial thermophilic phase, and early in the test about 35 to 40 days to enter the mature stage. The use of high-efficiency drain food waste collection bins in hsinchu county food waste composting site, for example, a daily treatment capacity of 8 CMD, compost produced volume 2 CMD, an annual cost of approximately $ 1,980,000; equally to this study as a daily treatment capacity to 8 CMD calculations, the amount of compost produced up to 3 ~ 4 CMD, while the annual cost up to about 7,320,000 ~ 8,220,000 yuan, Hsinchu County food waste composting site four times. The above results if extended to the community, offices and schools, restaurants can improve perishable food waste, odor and attract flies, in the family temporary, short time smelly distress caused by the back-end cleaning team reduction of volume reduction treatment can reduce the removal and labor costs. |
