中文摘要	隨著化工石化業高度發展，台灣重點產業的氨氮排放總量大增。對此，產業為因應環保署加嚴/新增管制的放流水標準，開始尋找含氮廢污水的最適處理方法。現有技術針對低濃度含氮廢污水多以生物處理，高濃度則係以汽提方式進行回收；然中濃度含氮廢水在處理上有廢液清運處理等其他問題產生，故中濃度含氮廢水仍亟待研發更友善環境的綠色新興處理技術。本計畫提出三項廢污水綠色處理技術：「氣提結合觸媒氧化中濃度氨氮廢水技術」、「觸媒還原中高濃度硝酸鹽氮廢水技術」及「生物球處理中低濃度硝酸鹽氮廢水技術」。在中濃度氨氮(200-5,000 mg/L)廢水處理部分，團隊結合氣提法及催化氧化型觸媒在某金表業模廠測試中可以達到94%以上的氨氮去除率。選用脫硝觸媒(DNC)搭配還原劑(如硫代硫酸鈉、廢氨水、醋酸鈉)來處理中高濃度的硝酸鹽氮廢水(500-5,000 mg/L)，此舉除了有極高的氮氣選擇性，亦可同步處理硝酸鹽氮及氨氮。PVA生物球技術應用在中低濃度硝酸鹽氮廢水處理(< 500 mg/L)，在高導電度硝酸鹽氮廢水測試下亦可將硝酸鹽氮處理至符合放流標準。本團隊亦完成六家廠商現地訪談與輔導、辦理專家諮商會議、評估整合性套裝式廢水處理設備。透過辦理研討會、實績成效參訪、技術教材編撰、紀實影片與成果發表至國內期刊與研討會，以增加本計畫所開發建立的三大綠色處理技術的曝光度。

摘要	Nitrogen-containing chemicals used in chemical and petrochemical industries significantly increase the discharging levels of ammonia nitrogen in many industrial wastewaters in Taiwan. Since the TW EPA has struck wastewater discharge standards for ammonia, many TW domestic industries are looking for more effective treatment methods for decontaminating nitrogen-containing wastewater. Conventional treatment of ammonia adopts biological method for low-concentration nitrogen-containing wastewater, while high-concentration nitrogen-containing wastewater is treated by stripping. However, these methods suffer several downsides, including time-consuming, energy-intensive, and additional need for secondary liquid-waste treatment. A more practical and effective alternative method is urgently needed to overcome the current shortcomings of poor ammonia removal in TW wastewater treatments. This project proposes three green wastewater treatment technologies to remove ammonia and nitrate from industrial wastewaters: (1) gas stripping combined with catalytic oxidative activated carbon (COAC) for treating medium-concentration NH3-N wastewater; (2) denitrification catalyst (DNC) for treating medium and high concentration of nitrate wastewater; and (3) polyvinyl alcohol (PVA) Bioball for treating medium and low concentration nitrate wastewater. For the treatment of medium-concentration (200–5,000 mg/L) NH3-N wastewater, an air stripping followed by COAC oxidation strategy was examined in a pilot scale. The result showed that the removal rate of NH3-N reached higher than 94% for the metal surface treatment industry. Denitrification catalyst (DNC) coupled with reducing agents (such as waste ammonia and sodium acetate) was used to treat medium and high concentrations (500-5,000 mg/L) of nitrate wastewater. The result of pilot test (nitrate: 200–400 mg/L) showed excellent nitrate removal, reaching the discharge standard under optimal conditions. PVA bioball was applied for the treatment of medium and low concentration (< 500 mg/L) nitrate wastewater. At the volume load of 2.5 kg NO3-N/m3-d, the nitrate concentration in the effluent water achieved < 30 mg /L. The pilot test (nitrate: 100-150 mg/L) results confirmed that bioball could effectively remove nitrate to meet the discharge standard. An expert consultation meeting has been held. On-site interviews with six manufacturers were conducted. The feasibility of integrated packaged wastewater treatment plants was assessed. In order to increase the exposure of the three major green processing technologies developed in this project, a seminar was held in the field. In addition, 3 DMs were made as technical textbooks, the contents of this project were filmed, and the results of this project were published in domestic journals and seminars.

摘要

Nitrogen-containing chemicals used in chemical and petrochemical industries significantly increase the discharging levels of ammonia nitrogen in many industrial wastewaters in Taiwan. Since the TW EPA has struck wastewater discharge standards for ammonia, many TW domestic industries are looking for more effective treatment methods for decontaminating nitrogen-containing wastewater. Conventional treatment of ammonia adopts biological method for low-concentration nitrogen-containing wastewater, while high-concentration nitrogen-containing wastewater is treated by stripping. However, these methods suffer several downsides, including time-consuming, energy-intensive, and additional need for secondary liquid-waste treatment. A more practical and effective alternative method is urgently needed to overcome the current shortcomings of poor ammonia removal in TW wastewater treatments. This project proposes three green wastewater treatment technologies to remove ammonia and nitrate from industrial wastewaters: (1) gas stripping combined with catalytic oxidative activated carbon (COAC) for treating medium-concentration NH3-N wastewater; (2) denitrification catalyst (DNC) for treating medium and high concentration of nitrate wastewater; and (3) polyvinyl alcohol (PVA) Bioball for treating medium and low concentration nitrate wastewater. For the treatment of medium-concentration (200–5,000 mg/L) NH3-N wastewater, an air stripping followed by COAC oxidation strategy was examined in a pilot scale. The result showed that the removal rate of NH3-N reached higher than 94% for the metal surface treatment industry. Denitrification catalyst (DNC) coupled with reducing agents (such as waste ammonia and sodium acetate) was used to treat medium and high concentrations (500-5,000 mg/L) of nitrate wastewater. The result of pilot test (nitrate: 200–400 mg/L) showed excellent nitrate removal, reaching the discharge standard under optimal conditions. PVA bioball was applied for the treatment of medium and low concentration (< 500 mg/L) nitrate wastewater. At the volume load of 2.5 kg NO3-N/m3-d, the nitrate concentration in the effluent water achieved < 30 mg /L. The pilot test (nitrate: 100-150 mg/L) results confirmed that bioball could effectively remove nitrate to meet the discharge standard. An expert consultation meeting has been held.
