嬚氣性 固定床 生物反應器에서 담체의 種類에 따른 유기성 폐수의 처리 특성에 관한 연구(Ⅱ) = The charateristics of organic wastewater treatment in an anaerobic packed bed bioreactor with two carriers(Ⅱ)

다국어 초록 (Multilingual Abstract)

In an attempt to develope the packing materials, two types of carriers was investigated in wastewater treatment using an anerobic packed bed bioreactor.
The followings are the results of this experiment.
1. Soft stone A as a carriers was superior to soft stone B in biogas production and methane content.
2. Soft stone A enhanced the COD removal efficieucy which was 90% above, and stabilized in volatile acid.
3. The slope of methane production with respect to the removal COD was 0.58㎥ CH₄/㎏ COD for soft stone A, and 0.35 for soft stone B.
4. The result of SEM photographs has shown that a lot of microoganisms are was attached in the soft stone A, and enwrapped it.
5. The mass transfer rate of microoganisrns from the liquid phase to the biofilm surface for soft stone A and B is C_(b)=C_(bo) exp(-0.025Θ_(AF)). C_(b)=C_(bo) exp(-0.034Θ_(AF)) respectively.
It was recommened that the effective carriers in wastewater treatment using an packed bed bioreactor in this experiment be soft stone A carriers.
