中文摘要	隨著高科技產業及相關供應鏈的高度發展，台灣重點產業的氨氮和硝酸鹽氮排放總量大增。對此，產業為因應環境部加強/加嚴/新增的氨氮和硝酸鹽氮放流水標準，開始尋找含氮廢污水的最適處理方法。尤其化工業及金屬表面處理業等含有硝酸鹽氮廢水的產業，大多面臨既有單元脫硝功能較差與可擴充空間不足等問題，因此急需尋求新的解決方案。另對於部分地區的生活污水(包含露營區、公共區域與社區)，因缺乏管理且受限於空間，導致傳統硝化脫硝生物處理無法於這些特定區域有效運轉。因此，亟需開發低污泥、低能耗且耐環境衝擊的生物處理系統。本團隊已於去年成功利用觸媒還原技術與聚乙烯醇(PVA)生物球技術處理廢水中硝酸鹽氮，今年度則繼續精進前述兩項技術，並建構套裝式模組。針對難降解的硝酸鹽氮廢水，採用今年改質後的脫硝觸媒(denitrification catalyst, DNC+)搭配還原劑來處理，可相較去年未改質觸媒大幅提升硝酸鹽氮去除率且可減少還原劑加藥量。脫硝生物球則驗證針對較高導電度的金屬表面處理業廢水，可達到不錯的處理效果。另外，生活污水依場域碳氮比(C/N)水質特性分成三組，以不同生物好氧/缺氧單元進行生物球測試，確認可用間歇曝氣方式操作來節省50%的曝氣電費，並使氨氮及硝酸鹽氮濃度穩定達標。在硝酸鹽氮工業廢水的實場驗證方面，本團隊已建構脫硝生物球與觸媒還原套裝式模組，且均具有前處理加藥系統與遠端數據擷取與監控功能，並在某不鏽鋼廠完成測試與現地實績成效參訪。在生活污水的實場驗證方面，則完成桃園順時埔聚落的生物球處理技術現地驗證與實績成效參訪，並協助某科技廠完成120 CMD生活污水的生物球硝化系統實廠設計、建置與試車。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、辦理新興廢水處理技術推廣暨臺印永續水環境論壇、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。

摘要	With the rapid development of the high-tech industry and its related supply chains, Taiwan has seen a significant increase of NH3-N and NO3-N in the effluent. In response to the strengthened or newly introduced discharge standards by the Ministry of Environment, industries have begun to search for optimal treatment methods for nitrogen-containing wastewater. Particularly, industries such as the chemical and metal surface treatment sectors, which generate NO3-N containing wastewater, often face challenges like poor denitrification performance in existing units and limited space for expansion. Thus, there is an urgent need for innovative solutions. Furthermore, in certain areas, such as camping sites, public areas, and communities, sewage lacks proper management and is constrained by limited space, making traditional nitrification-denitrification biological treatment ineffective in these specific regions. Therefore, there is a pressing need to develop a biological treatment system that is low in sludge production, energy-efficient, and resilient to environmental impacts. Last year, our team successfully utilized catalytic reduction technology and polyvinyl alcohol (PVA) bio-pellet technology to treat nitrate nitrogen in wastewater. This year, we have further improved both of these technologies and constructed packaged modular systems. For the treatment of refractory NO3-N wastewater, we have modified the denitrification catalyst (DNC+) with reduced dosing of reducing agents, resulting in a significant increase in NO3-N removal compared to the unmodified catalyst used last year. The denitrification bio-pellets have shown good performance in treating higher conductivity wastewater from metal surface treatment industries. In addition, sewage can be divided into three groups based on the carbon/nitrogen (C/N) ratio of the site-specific water quality characteristics. Bio-pellet tests were conducted using different biological aerobic/anoxic units, confirming the feasibility of intermittent aeration to save 50% of aeration power cost while maintaining stable concentrations of NH3-N and NO3-N to meet the discharge standards. In terms of on-site verification of industrial NO3-N wastewater, our team has constructed denitrification bio-pellets and catalytic reduction modular systems, each equipped with pretreatment dosing systems and remote data collection and monitoring functions. These systems have been tested and have shown promising results at a stainless steel plant. For on-site verification of sewage treatment, our team successfully verified the bio-pellet treatment technology in the Shunshi Village in Taoyuan, and also assisted a high-tech company in designing, building, and start-up the bio-pellet nitrification system for 120 CMD of sewage. We conducted on-site interviews with six companies and organized expert consultation meetings. We also held the Promotion of Emerging Wastewater Treatment Technologies ＆ Taiwan-India Forum on Sustainable Water Environment.

摘要

With the rapid development of the high-tech industry and its related supply chains, Taiwan has seen a significant increase of NH3-N and NO3-N in the effluent. In response to the strengthened or newly introduced discharge standards by the Ministry of Environment, industries have begun to search for optimal treatment methods for nitrogen-containing wastewater. Particularly, industries such as the chemical and metal surface treatment sectors, which generate NO3-N containing wastewater, often face challenges like poor denitrification performance in existing units and limited space for expansion. Thus, there is an urgent need for innovative solutions. Furthermore, in certain areas, such as camping sites, public areas, and communities, sewage lacks proper management and is constrained by limited space, making traditional nitrification-denitrification biological treatment ineffective in these specific regions. Therefore, there is a pressing need to develop a biological treatment system that is low in sludge production, energy-efficient, and resilient to environmental impacts. Last year, our team successfully utilized catalytic reduction technology and polyvinyl alcohol (PVA) bio-pellet technology to treat nitrate nitrogen in wastewater. This year, we have further improved both of these technologies and constructed packaged modular systems. For the treatment of refractory NO3-N wastewater, we have modified the denitrification catalyst (DNC+) with reduced dosing of reducing agents, resulting in a significant increase in NO3-N removal compared to the unmodified catalyst used last year. The denitrification bio-pellets have shown good performance in treating higher conductivity wastewater from metal surface treatment industries.
