TFT-LCD (Thin-film transistor liquid crystal display)為台灣近年重點發展之工業之一,而隨著其產量的增加,大量的廢水也同時產生,預計TFT-LCD工業之總廢水量會高達200,000 CMD,而其中33%為有機廢水,主要之成分包括二甲基亞楓(Dimethylsulfoxide, DMSO)、乙醇胺(Monoethanolamine, MEA)以及氫氧化四甲基銨(Tetramethylammonium hydroxide, TMAH),而這些物質在生物處理上會有一定的困難,因其不容易被微生物利用。
本研究建立二序批式反應器(Sequencing Batch Reactor, SBR)以探討TFT-LCD有機廢水之生物可降解性,以及其降解效率。此二SBR分別以無氧/好氧(Anoxic/Oxic, A/O)以及好氧(aerobic)之方式操作,其進流基質為人工配置之TFT-LCD有機廢水,主要含有DMSO、MEA及TMAH,經過長期監測發現,DMSO、MEA及TMAH之去除率均達99%以上,此顯示生物處理此種廢水之可行性,而MEA及TMAH降解中產生之氨氮則會經硝化作用轉化為硝酸鹽氮。
本研究也利用反應槽中培養之污泥進行了一系列之批次實驗以探討DMSO、MEA及TMAH在好氧、缺氧及厭氧狀態下之降解動力以及機制。從實驗結果發現,DMSO在厭氧狀態下會有較高之降解速率,最大之比DMSO降解速率約為34 mg DMSO/g VSS-hr,但在厭氧環境下,DMSO會轉化為臭味物質DMS (dimethylsulfide),此為處理DMSO其中之最大問題,而在好氧環境下,DMSO之降解效率雖較緩慢,但其最終產物為硫酸根,減少臭味問題。而MEA則在好氧、厭氧及缺氧(反應槽無氧段)環境下皆有頗高之降解速率,最大之比MEA降解速率在好氧狀態下得到,其數值約為121 mg MEA/g VSS-hr,其降解之產物為氨氮,而在好氧環境下氨氮會進一步氧化成硝酸鹽氮。TMAH在好氧狀態下有較佳之降解速率,最大之比TMAH降解速率約為8 mg TMAH/g VSS-hr,而在厭氧狀態下,TMAH幾乎沒有被降解,TMAH降解之產物為氨氮。
本研究也探討一實廠TFT-LCD廢水處理廠之效能,該廠之主要污染物為TMAH,其主要之處理設施為一UASB厭氧反應槽與一好氧活性污泥槽。經長期監測結果發現該廠之TMAH去除率達99%,顯示該廠能有效處理含TMAH之廢水,而其中UASB去除約90%之TMAH,而氨氮為其主要的產物,但過高之TMAH則因HRT不足而分解不完全。
本研究發現,生物降解TFT-LCD有機廢水為可行的,但需要進一步之研究以找到最佳之處理程序。
The amount of pollutants produced in manufacturing processes of TFT-LCD (Thin-film transistor liquid crystal display) substantially increases due to an increasing production of the opto-electronic industry in Taiwan. The total amount of wastewater from TFT-LCD manufacturing plants is expected to exceed 200,000 CMD in the near future. Typically, organic solvents used for TFT-LCD manufacturing processes account for more than 33% of the total TFT-LCD wastewater. The main components of these organic solvents are composed of the stripper (dimethyl sulphoxide (DMSO) and monoethanolamine (MEA)), developer tetra-methyl ammonium hydroxide (TMAH) and chelating agents. These compounds are recognized as non- or slow-biodegradable organic compounds and little information is available regarding their biodegradability.
In this study, the performance of an anoxic-oxic sequencing batch reactor (A/O SBR) and an aerobic SBR treating synthetic TFT-LCD organic wastewater was evaluated. Long-term experimental results showed that both SBRs were able to achieve stable and satisfactory removal performance for DMSO, MEA, and TMAH. The removal efficiency for all three compounds was as high as 99%.
In addition, batch tests were conducted to study the degradation kinetics and mechanism of DMSO, MEA, and TMAH under aerobic, anoxic and anaerobic conditions at different initial substrate concentration. Results showed that DMSO had the highest degradation rate under anaerobic condition, with the value of about 34 mg DMSO/g VSS-hr. MEA and TMAH had higher degradation rate under aerobic condition. MEA can be degraded under all conditions without any difficulties. The highest specific MEA degradation rate, about 121 mg MEA/g VSS-hr, was obtained under aerobic condition. Ammonia seemed to be the end product of MEA degradation under all three conditions. TMAH degradation seemed to be inhibited under anaerobic condition. Only little TMAH degradation was observed. The highest specific TMAH degradation rate, about 8 mg TMAH/g VSS-hr was obtained under aerobic condition. The end product of TMAH degradation was also seemed to be ammonia.
In the previous tests, the intermediates or products formed in DMSO degradation was not known. Therefore, we have also conducted a few tests to study the degradation mechanism of DMSO degradation under aerobic, anoxic and anaerobic conditions. Results showed that under aerobic condition, almost all DMSO was converted into sulfate, with little amount of DMS observed during the period of investigation. The final product of DMSO degradation under both anoxic and anaerobic condition was DMS, which may cause the odor problem.
The performance of a full-scale TFT-LCD wastewater treatment plant (plant G), comprised a UASB and an aerobic tank, was also investigated in this study. TMAH was the main component of plant influent. Results showed that plant G achieved good removal performance for TMAH. The removal efficiency of TMAH was 99% at an average 625 mg/L of TMAH. Batches were conducted to study the TMAH tolerance of UASB and aerobic tank sludge. In this study, 2,000 mg/L TMAH was degraded in 10 hours by UASB sludge. Methane and ammonia were produced during TMAH degradation. For aerobic tank sludge, 550 mg/L TMAH can be degraded gradually in 48 hours.
This study showed that biological treatment of TFT-LCD organic wastewater was feasible. But further study should be done to investigate the optimum condition for the processes.
