蔬菜廢棄物堆肥化及其經驗模式研究生:王竣弘 指導教授:黃汝賢摘
要為瞭解蔬菜廢棄物堆肥化之技術可行性,乃設計製作實驗室規模填充式
反應槽,以確立堆肥化之主要影響參數及最適操作條件,並據以推展堆肥
化經驗模式。又欲深入瞭解堆肥化過程有機質之分解機制,更進一步設計
了堆肥化二段式生物反應動力模擬實驗流程。就堆肥穩定化參數而言,耗
氧率及二氧化碳產生速率較能靈敏地反映微生物活性;C/N比、總固體物
損失率及總揮發性固體物損失率可反映固體基質被微生物利用程度;固體
物萃取液CODs、Org.-N及NH3-N則有助於瞭解有機質之分解情形。依堆肥
化過程溫度、耗氧率及二氧化碳產生速率等監測參數之變化,似可臆測有
機物之分解應具階段性,即易分解物(如醣類)先在堆肥化初期為微生物分
解,而難分解物(如纖維素、木質素)則在堆肥化中、後期分解。堆肥化過

Vegetable Waste Composting and Its Empirical ModelGraduate
Student:Chun-Hung Wang Advisor:Ju-Sheng HuangABSTRACT
Laboratory-scale packed-bed reactors were constructed and used
to ascertain the main influential parameters on composting of
vegetable waste and the optimal composting conditions.
Together, the empirical model was drawn by fitting in the
experimental data with an appropriate algebraic equation.In
addition, a simulated two-stage bioreactor system was
established to scrutinize the mechanism of degradation of
organic material during the composting. Among the stability
parameters of composting,the O2 consumption rate and CO2
evolution rate can reflect the sensitivity of microbial
activity; the C/N ratio and total (volatile) dry-solids loss can
reveal the decomposition degree of solid substrate; soluble COD,
Org.-N and NH3-N measured from water extracts of the compost are
helpful to illustrate the decomposition behavior. According to
the observed time course of temperature, O2 consumption rate and
CO2 evolution rate during the composting,the decompos The
empirical model expressed as the form of second-degree algebraic
was drawn from 19 sets of experimental data, and approved by F-
test.This reveals that the model obtained can be used in
practice to illustrate that the dependent variables (i.e. total
dry-solids loss and total volatile dry-solids loss) varies with
the independent variables (i.e. continuous aeration rate, mixing
ratio of vegetable waste with 80% moisture to rice hull,
fermentation temperature and reaction time).Key words: vegetable
waste, composting, stability parameter, influential parameter,
two-stage biochemical kinetics, empirical model.
