dc.description.abstract | 第三年研究工作為進行一實驗室中微生物對畜舍
產生氨氣之生物衰減實驗。氨氣為豬舍中主要氣態有害
物之一,形成豬舍內甚大之污染問題並造成地下水硝化
作用,對動物及人體亦具有相當之健康危害。本研究目
的為,在無控溫下以低廉、結合多樣性微生物之無機及
有機生物濾床形成之過濾器來減低豬舍惡臭。本研究使
用泥煤及無機媒床為生物過濾材,將氣體灌入使通過此
生物過濾管柱。結果顯示當室溫介於27.5±4.5oC,氣流速
率介於0.03–0.06 m3 h-1 時,氨氣濃度200 ppm 之生物移
除效率明顯介於99–100%間。此實驗過程下,氨氣於生
物過濾小於1 ppmv (0.707 mg m-3)時溢散,生物過濾性能
於此廣大範圍溫度間,長期之生物過濾系統可以有效之
低成本操作而達到去除效率。本研究中所獲得之最大氨
氣移除效率之去除容量為2.217 g m-3。本生物過濾器具有
高硝化效率並可於減壓情況下控制氨氣污染程度,由實
驗起始操作至終結反應來看,本生物過濾氣之生物膜具
有一優秀之穩定性。 | zh_TW |
dc.description.abstract | We contacted a laboratory test for microbial
degradation of livestock-generated ammonia in this year.
Ammonia, one of the gases produced in greatest volume
from swine waste, causes one of the biggest pollution
problems in swine farming resulting in ground water
nitrification and adverse effects on animal and human health.
Our objective is to neutralize malodor by using biofilters
packed with inexpensive inorganic and organic packing
material combined with multicultural microbial load at
uncontrolled temperatures. Peat and inorganic supporting
materials were used as biofiltration matrix packed in a
perfusion column through which gas was transfused. Results
show the ammonia removal significantly fell in between
99-100 % when ammonia concentration of 200 ppmv was
used at different gas flow rates ranged from 0.030 – 0.060
m3 h-1 at a fluctuating room temperature of 27.5±4.5°C.
Under these conditions, the emission concentration of
ammonia that is liberated after biofiltration is less than 1
ppmv (0.707 mg m-3) over the period of our study,
suggesting the usage of low-cost biofiltration systems for
long-term function is effective at wider ranges of
temperature fluctuations. The maximum (100%) ammonia
removal efficiency was obtained in this biofilter was having
an elimination capacity of 2.217 g m-3 h-1. This biofilter had
high nitrification efficiencies and hence controlled ammonia
levels with the reduced backpressure. The response of this
biofilter to shut down and start up operation showed that the
biofilm has a superior stability. | en |
