本研究結果證明最適微生物分解氯酚化合物之溫度及pH值與原生長環境相
同,還原劑則以以 Titanium(III)citrate 的效果最佳;而硫酸鹽、硝酸
鹽及三價氫氧化鐵均可抑制三氯酚之脫氯作用, 四價氧化錳則可促進三氯
酚脫氯, 但對二氯酚產物則有抑制現象;硝酸鹽金屬除鎳以外,鉛、鋅、
銅、汞、鎘等皆可抑制硝酸鹽之抑制脫氯作用,換言之,即具有微量去氯
效果;氯化鹽金屬類以鋅之脫氯效果最明顯,銅於低濃度下可促進,高濃
度 (100mg/L)則完全抑制脫氯作用,而鉛在低濃度下不影響脫氯,高濃
度 (100mg/L)則促進促進三氯酚脫氯, 但抑制二氯酚產物之脫氯;有機物
如丙酮酸鹽、醋酸鹽僅對二氯酚產物有促進脫氯現象,乳酸鹽則不影響脫
氯,但葡萄糖及維他命 B12各具抑制及延遲脫氯效果;由微生物抑制劑結
果得知,甲烷菌並非本研究分解氯酚化合物的主要族群,而具三氯酚脫氯
作用之微生物可能為革蘭氏陰性菌,二氯酚則為革蘭氏陽性菌,且經三氯
酚誘導之脫氯酵素對二氯酚不具脫氯效果,但經二氯酚誘導之脫氯酵素對
三氯酚具有脫氯效果;另以迪化污水處理廠廢水及嘉義中油煉油廠牌水口
廢水為培養基,發現其脫氯效果優漁人工培養基。

In this study, we investigated the potential for reductive de-
chlorination of chlorophenols by municipal sewage sludge
accli- mated to 2,4-DCP and 3,4-DCP. Incubation factors
including di- fferent concentration of chlorophenols, reducing
agents, elec- tron acceptors, metals, organic substrate and
microbial inhibi- tors on dechlorination by acclimated and
unacclimated were con- ducted. After six months of acclimation,
the anaerobic mixed cul- tures could dechlorinate
2,4,6-TCP.,2,4-DCP and 3,4-DCP, yet not for pentachlorophenol.
The optimal dechlorination temperature was 30℃, pH value was
7.2, and reducing agents was titanium(III)ci- trate.
Dechlorination of 2,4,6-TCP was inhibited by sulfate, ni- trate
or ferric(III)hydroxide,but was increased by manganese(IV)
oxide except that 2,4-DCP was accumulated.When lead,zinc,
copper, mercury,cadium or nickle was added at the concentration
of 1mg/L as nitrate salts, only lead, mercury or nickle delayed
dechlori- nation. However, higher concentration of lead, zinc,
copper,mer- cury or cadium appeared antagonism effect of
nitrate, yet only trace dechlorination of TCP was found.
Addition of 10mg/L, 50mg/L or 100mg/L of nickle results showed
no dechlorination. When me- tals were added as chloride salts,1
mg/L of lead showed no influ- ence for dechlorination of TCP.
However,100mg/L of lead increase TCP dechlorination, yet
accumulation of DCP product. Dechlorina- tion of TCP or DCP
also increased by addition of zinc at differ- ent
concentrations, except that DCP was accumulated at the metal
concentration of 1000 mg/L. As for copper, no influence for TCP
