印刷電路板有機廢液多以物化及生物處理法去除COD，但當污染物成份過於複雜或較難分解時，其去除效果則不顯著。電路板化學銅廢液以化學混凝沉澱法處理為主，其缺點為產生大量的重金屬污泥。
本研究目的為藉由Fenton-Ferrite Process及UV/H2O2-Ferrite Process二種組合程序去除PCB廢水中之有機物及重金屬，使上澄液能符合法規標準，且產生之重金屬污泥可視為一般事業廢棄物。
Fenton及UV/H2O2程序主要探討因子為：亞鐵及H2O2加藥量、pH值、反應時間與加藥方式等，並尋求較好的操作條件以結合後續Ferrite Process。結果顯示Fenton適合在酸性條件(pH=2)，UV/H2O2系統適合在中性條件(pH=8)操作，H2O2加藥量過多或太少皆會使去除效率下降。
Fenton及UV/H2O2程序完成測試後，接續Ferrite Process測試重金屬廢水，其中Ferrite Process主要以三段式進行反應，操作條件為控制溫度、pH值及Fe/M莫耳比。Ferrite Process在處理銅金屬廢水，Fe/M莫耳比率為10倍，結合Fenton、UV/H2O2及Ferrite Process成為Fenton-Ferrite Process及UV/H2O2-Ferrite Process二種來處理PCB實場廢水，其上澄液所含有機物和重金屬皆可符合法規標準，汙泥初步證明為一般事業廢棄物，此污泥粒晶格粒徑皆小於100 nm並擁有磁性，可朝後續回收再利用發展。

Biological and physical chemistry treatment methods always are used to remove COD of organic wastewater contains PCB. The effect is not obvious when the compositions of pollutant are too refractory or complicated. The primary treatment method of wastewater containing copper is chemical coagulation/sedimentation and its disadvantage is producing a large of sludge.
The objective of this study, using two combinative method of UV/H2O2-Ferrite Process and Fenton-Ferrite Process, is to remove organic compounds and heavy metal in real wastewater. Not only supernatant liquid could meet the standard of discharge wastewater but also produce general(non-hazardous) industrial wastes of heavy metal.
The primary operation condition of Fenton and UV/H2O2 process, was ferrous ion and hydrogen peroxide concentration, pH, reaction time, and chemical dosing, searching best operation condition to combine with Ferrite Process. Operation of Fenton and UV/H2O2 process under acid condition (pH=2) and neutral condition (pH=8) showed the best operation condition of Fenton and UV/H2O2. The removal decreased when the dose of hydrogen peroxide was added too more or too less.
As Fenton and UV/H2O2 process test finished, Ferrite Process is next used for treatment of heavy metal wastewater; Ferrite Process conducted as three stages and the operation conditions were controlled with temperature, pH and the ratio of Fe/M mole. The results showed that the best removal of treatment of copper containing wastewater by Ferrite Process achieved when the ratio of Fe/M mole was at 10. Treatment of PCB industrial real wastewater by Fenton-Ferrite Process and UV/H2O2-Ferrite Process which combined with Fenton, UV/H2O2 and Ferrite Process. The supernatant liquid containing organic compounds and heavy metal both could meet the standards of discharge wastewater and the sludge was judged with general(non-hazardous) wastes. The characteristic of the sludge were the diameter lattice less 100 nm and with magnetism and to develop recovery and utilization in a further work.
