由於水資源有限, 而各種用途之需求量日益增加, 特別是工業用水,
已出現嚴重短缺之現象, 如何處理與再利用工業用水, 不但對環境保護十
分重要, 亦成為企業追求永續經營所必須面對之嚴肅課題.
臺灣有許多工業排放含重金屬廢水至承受水體, 嚴格之環保法規已要求重
金屬廢水排放者處理其廢水, 以合乎排放標準. 對於含重金屬廢水, 一般
之處理方法有電解法, 沈澱法, 及離子交換法等, 其中離子交換法可避免
含重金屬污泥之產生, 而造成二次污染, 處理成本亦較電解法經濟, 又可
藉適當之操作策略,將廢水中之重金屬分離與回收. 欲適當操
作離子交換塔, 則必須了解其動態行為, 而離子交換塔之動態行為可由一
組複雜且相關連之偏微方程式來描述, 其數值解法繁複且耗時. 本研究採
用非線性波傳遞理論, 藉由波的概念, 避免直接解偏微方程式, 即能預測
離子交換塔之貫穿與再生曲線. 預測結果可作為離子交換塔操作者操作依
據, 並可探討廢水中重金屬之回收策略. 本研究先做批示實驗, 決定氫與
銅i 氫與鎳之離子交換平衡關係, 再做一系列管柱實驗, 測量含銅鎳廢水
之貫穿與再生曲線, 根據本研究之結果, 吾人可提出利用離子交換法分離
銅與鎳之操作策略.

Due to limited water resources and increasing water demands
of various kinds, especially of industries, how to treat and
reuse industrial wastewatershas become not only a very important
problem to environmental protection but also a crucial issue to
industries seeking sustainable development. Wastewatercontaining
heavy metals is one of the most difficult industrial wastewaters
totreat. Although the conventional chemical precipitation
method, which is the most popular one, is quite effective in
removing heavy metals from wastewatersdeal with and usually
causes a secondary pollution problem. On the contrary, ion
exchange process are also very efficient but generate much less
sludge. Moreover, different heavy metals could be separated
and recovered and ideal state of the so-called zero discharge
could be achieved via adequate ion exchange resin
selection, process design, and column operation.
In order to operate ion exchange columns adequately, the column
dynamics which is governed by a set of coupled partial
differential equations and associated equilibrium algebraic
equations must be understood. Instead of solving the tedious
equations, this research project modify the traditional wave
propagation theory to predict the breakthrough and regeneration
curves under various operating conditions. Batch experimental
tests were conducted to obtain the exchange equilibria of H/Cu
and H/Ni systems, and column tests were conducted to obtain the
breakthrough and regeneration curves under various
operating conditions. The experimental results showed that the
wave theory indeed predicts the column dynamics well.
Operating strategy for Cu and Ni separation by ion exchange
was proposed based on this research project.
