摘要

染顔料製程産廢水的BOD濃度與COD濃度之比值約等於0.1左右，是一種高難度被生物分解之工業廢水；製漿造紙程序中最嚴重之汙染源爲製漿廢液，其溶解性的有機物含量甚高，色度呈黑褐色，爲高難度處理之廢水；合成樹脂工業所排放之廢水含生産聚酯反應後之縮合廢水及製造乳化樹脂反應後以水洗滌反應槽所衍生之廢水等，其COD濃度變異範圍非常大，亦屬很難處理紙漿、合成樹脂及石化工業製程所排放廢水的處理功能，效果及應機構，並利用訪處理技術對染顔料，紙漿及合成樹脂工業廢水進行最適化之處理流程設計。依本研究結論，排放廢水經調和及化學前處理後現利用活性碳泥法處理，其程序操作穩定，處理後水質可符合環保署法定之放流水管制標準。

Wastewater discharges coming from the dye, pulp and synthetic resin industry contain a multitude of difficult biodegradable compounds. The wastewater can be characterized as a highly variable, hignly colored wastewater which is typically high in COD and organic concentration.
The main purpose of this research is to evaluate the treatability of the organic wastewater by using chemical coagulation and flocculation and activated sludge with powdered activated carbon treatment processes. This work is also to explore the biocarbon reaction mechancisms in the biophysical reactor.
The experimental results show that the dye, pulp and synthetic resin processing wastewater treated by powder activated carbon sludge treatment is superior in sludge yield coefficient, organic materials adsorbed on powder activated carbon, resistance to shock loads and COD removal to conventional activated sludge treatment.
This experimental also demostrates that after the treatment of the dye, black liquor and synthetic resin wastewater by powdered activated carbon sludge method the effluent discharges meet the permit set up by the environmental protection agency of R.O.C.
