染料污染處理及環保

關於染料工業之污染來源主要包括化學反應不完全之廢料、化學反應的副產品，重油燃燒廢氣、物料洩漏等，其中不純物料及副產品常排入廢水處理系統造成處理上的重重困難。本文著眼於強調染料污染對廢水生物處理系統的不利影響、減廢與回收再利用的雙贏原則、以及染料廢水在生物處理上的範例與最適化處理流程。其中，工業減廢技術，在由學者、專家、及實際參與染料製程之相關人員與工業減廢小組所共同編輯之工業減廢技術手冊以巨細靡遺的詳載了染料工業製程之相關科學(化學與機械)，並介紹其主要污染來源及相對之處理原則。本報告則應用實驗的方法，也Arthur自動化微生物活性與分解反應速率監控儀實際進行試驗，對染料工業之工業減廢技術加以佐證及凸顯其施行的重要性。並根據試驗結果引以為範例，藉由試驗圖形的判讀了解不同的染料廢水在處理上因應之處理情形、最佳操作參數、反應處理停留時間、生物可分解性與毒性物質對微生物的抑制性等。最後，則以流程圖簡明概述染料廢水最適化處理流程－二階段活性碳泥法，以供業界參考。

Wastewater discharges coming from the dye stuff industry contain a multitude of difficult biodegradable compounds. The wastewater can be characterized as a highly variable, highly colored wastewater. A biological wastewater treatment plant uses a natural biological process-metabolism, to destroy waste dye stuff organic matter. The most important parameter in the Arthur Operation Strategy is ＂treatment time＂. The main purpose of this research is to evaluate the treatability-toxicity of the dye stuff wastewater by using the Arthur Instrument. This work points out that changes in degrees of treatability, due to changes in substance of samples, were shown by developing reaction rate and oxygen volume consumption graphs. These graphs were developed from the data obtained from a series of tests at various samples to activated carbon sludge. In this research the important point was that the toxins were tested using the mixed liquor from dye stuff industry giving us a direct indication of the toxic effect and an actual measurement of the treatment time. Based entirely on biological measurements, we have an actual message of the length of time it takes for the microbes in dye stuff industry to treat the waste coming into aeration basin. Finally, this paper shows that the best treatment process for dye stuff industry is two-stage activated carbon sludge process.
