近年來高科技產業不斷創新研發新產品，生產製程會調整變動，另外提升產品良率時，化學原物料用藥品牌、種類或藥劑量也會調整，造成製程排放廢水性質也不穩定。在放流水法規管制限值越加嚴格下，廢水處理系統，也必須進行功能提升，才能符合放流水法規。因此本研究針對某光電廠有機廢水中之氨氮及總有機碳為實驗基質，利用上流式厭氧污泥床(UASB)結合兩段式高效率生物網膜(BioNET-1&2)等高體積負荷之生物處理技術，進行去除氨氮與TOC之研究，並探討某光電廠有機廢水水質變化及處理效率。本研究利用原高濃度有機廢水、TMAH及DMSO混合，模擬出產線製程改變後的廢水水質，以水質調查分析結果作實驗設計基礎，經評估過後，將實廠系統改建完成，經由污泥馴養階段、長期處理功能驗證，並因生物處理效率受原水物質抑制而再進行加藥、生物擔體、出流水氨氮處理效率提升等研究，重新檢討實驗設計。並利用處理效率提升實驗結果，將BioNET-1反應槽另外新增碳酸氫鈉加藥系統，提供微生物無機碳源，促進細胞同化作用及硝化作用所需鹼度，並調整鼓風機管路配置，使生物擔體在反應槽中有良好的滾動狀態；最終處理效率分析與驗證時，BioNET-1氨氮去除率提升14%，出流水氨氮值皆低於20 mg/L，進而減少BioNET-2反應槽負擔；BioNET-2氨氮去除率更由27%大幅度提升至72%，出流水氨氮值皆低於20 mg/L，符合放流水法規值(30 mg/L)。UASB結合兩段式BioNET-1&2技術，在最終驗證階段處理效果佳，能有效處理有機廢水，但仍需注意因製程變動影響處理效率，尤其某光電廠為老舊工廠，土地面積及空間有限情況下，並無足夠體積之調勻槽讓廢水調勻緩衝，導致高濃度廢液在稀釋調勻不完全下，造成原水水質波動性大。

In recent years, high-tech industries continue to innovate and develop new products, and the production process will be adjusted and changed. In addition, when the product yield is improved, the brand, type, or dosage of chemical raw materials will also be adjusted, resulting in unstable wastewater discharge properties of the process. As the regulatory restrictions of drainage regulations become more stringent, wastewater treatment systems must be improved to meet the requirements of drainage regulations. Therefore this study in an optoelectronic factory in organic wastewater treatment of ammonia nitrogen and total organic carbon in the matrix, the experiment using the up-flow anaerobic sludge bed (UASB) combined with two sections of high efficient biological omentum (BioNET-1&2) high volume load of biological treatment technology, for the study of the removal of ammonia nitrogen and TOC, and discusses some optoelectronic factory organic wastewater quality and processing efficiency. In this study, the mixed raw high concentration organic wastewater, TMAH, and DMSO were used to simulate the wastewater quality after the production line process was changed. The experiment was designed based on the results of water quality investigation and analysis. After the evaluation, the actual plant system was rebuilt. After the sludge domestication stage, long-term treatment function verification, and due to the raw water material inhibits biological treatment efficiency, the research on dosing, biological support, and effluent ammonia-nitrogen treatment efficiency improvement was carried out, the experimental design was reviewed. In this study, based on the results of the treatment efficiency improvement experiment, the Bionet-1 reaction tank was equipped with a sodium bicarbonate dication system to provide the alkalinity required by microbial inorganic carbon source to promote cell assimilation and nitrification to adjust the configuration of the fan pipeline and make the biological support have a good rolling state in the reaction tank. The removal rate of BiONET-2 ammonia nitrogen was significantly increased from 27% to 72%, and the ammonia nitrogen value of the effluent water was all lower than 20 mg/L, which was in line with the legal value of Effluent Standards (30 mg/L). UASB combined with the two-stage Bionet-1&2 technology has a good treatment effect in the final verification stage and can effectively treat organic wastewater. However, it should be noted that the processing process changes will affect the treatment efficiency, especially in the case of an old optical power plant with limited land area and space, and there is no homogenizing tank of sufficient volume for the homogenizing and buffering of wastewater, resulting in a significant fluctuation of raw water quality.
