目前台灣地區之主次要河川有半數以上受到不同程度的污染,飲用水之水
源中,含有大量的人工合成及生物代謝所產生的有機污染物,大幅增加了
淨水廠的處理成本並使飲用水的安全性也相對降低。本研究乃以高雄地區
之 L淨水廠為研究對象,進行現場水樣調查,並由水樣調查所得之數據經
統計分析,來探討本水廠之水質特性、傳統淨水程序單元對微量有機物去
除功能與各項有機替代參數(Surrogate Parameters)之相關性。結果發現
原水的濁度、導電度、游離氨氮等皆有逐年增加的趨勢,至於總有機碳(
Total Organic Carbon, TOC)則近年來變化不大,且大多低於3.00 mg/L。
清水的可吸附性有機化物 (Adsorbable Organic Halogen,AOX)在56.8
∼ 248.8μg/L之間,總三鹵甲烷(Total Trihalomethanes, TTHMs)
在7.2∼ 37.7μg/L之間。TOC因程序單元操作的累積去除率為10%,
TTHMs與AOX皆隨操作單元之進行而增加。至於清水的AOX : TTHM 濃度比
為6.3,若以氯等似比值計算,則 TTHM 大約占 AOX 的13.6%。原水的
紫外光吸光值( Ultraviolet Absorbance, UV254)對TOC有良好的線性關
係,顯示UV254是一個可用在對TOC的監測及預測的有機替代參數。
At present, some of the surface water sources for public water
supply in Taiwan have been heavily polluted. As a result, the
ammonia-nitrogen and organic contents of raw water have been
increased drastically.Although the conventional prechlorination
-coagulation-sedimention-filtration processes employed by the
local treatment plants are effective for the removal of diss-
olved organics is less than desirable. Furthermore, prechlori-
nation may form carcinogeneous halogenated organics in the
treated water. In the study, first, sampling and analying water
quality were conducted. With statistical analysis of research
data,the water quality characteristics, removal of trace
organic by conventi- onal operation unit and correlations
between the organic surr- ogate parameters were studied. The
result indicated that the turbidity, conductivity and ammo- nia-
nitrogen were increasing year by year. Total organic carbon
(TOC) varied little and was less than 3.00 mg/L. Adsorbable
organic halogen(AOX) of treated waters were 56.8 ∼ 248.8 μg/L
and TTHMs were 7.2 ∼ 37.7 μg/L. The accumulated removal rate
of TOC was 10%. TTHM and AOX were increasing by operation
unit. Treated water were found to contain a AOX-to-TTHM ratio
of approximately 6.3:1. On a chlorine-equivalent basis, the
TTHMs comprised approximately 13.6% of the AOX concentration.
UV absorbance correlated strongly with TOC concentration in raw
water, suggesting that UV absorbance could serve as a valuable
surrogate for measuring TOC.
