鑒於產業發展迅速，既有管末水質監測模式已無法快速有效地反映新興產業廢水水質特性。本計畫針對新興產業已研擬相關污染預防管理與監測機制，包含「前端製程化學品管理」與「末端廢水水質監測機制」兩大方向，前者希冀藉由強化既有水污染防治措施許可文件中原物料申報內容，確實掌握事業製程化學品使用種類與特性，要求事業單位進一步評估特定污染物於廠內各媒介流布現況，包含廢水、廢氣、廢棄物 (廢溶劑）或廠內回收再利用等；後者則調整既有廢水污染物的監測方式，在現行放流水標準尚未訂定管制標準前，優先增加「生物急毒性」、特定污染物或總量指標 (如總有毒有機物TTO) 之檢測申報，促使事業單位善盡污染預防之責。 國內諸多事業均具氨氮污染潛勢，依據調查結果顯示整體事業氨氮排放總量為70,063 kg/day (依據事業的總排放水量乘以平均濃度計算所得)，其中最大貢獻來源係為化工業，佔所有氨氮污染總量的32.6%，其次則為科學工業園區專用下水道、石油化學業和畜牧業；化學工業責任照顧協會、棉布印染整理工業同業公會、絲綢印染整理工業同業公會和皮革公會等產業公會認同廢水含氮污染前置評估調查評估工作，且具配合意願，有助於後續管制標準值之推動。 本計畫針對放流水平均值管制、重金屬管制標準、土石採集/加工業和二氧化矽製造業的懸浮固體管制標準、染整業色度處理技術以及殯葬業廢水管理等完成相關評析，以供後續修訂標準之參考。

Due to the fast development, the current wastewater monitoring procedure cannot effectively reflect wastewater characteristic of emerging industry. This study has panned several mechanisms in regard of pollution prevention and monitoring. The suggested procedures included more detailed chemicals disclosure in the manufacturing process (upstream) and wastewater monitoring (downstream). The former aims to clarify the raw materials used by the industries by strengthening the declaration in the existing Water Pollution Control Measure Plans and Permit. The manufacturers are responsible to disclosure the fate of specific pollutant in the factory including wastewater, exhaust gas, waste (waste solvent) or recycling usage. The latter is to suggest that the Environmental Protection Agency (EPA) should consider to add more items for detection and report such as acute toxicity, specific pollutant and total pollution index (such as TTO) before the Effluent Standard are set up. There are many industries bearing ammonia-nitrogen in their wastewater. The investigation estimated that total amount of ammonia-nitrogen discharged from all industries was 70,063 kg/day. The largest contributor was chemical industry and its load was estimated as 32.6% of the total amount of ammonia-nitrogen. Besides, sewage system of Science Park, petrochemical industry and poultry also have high pollution potential. Most industry associations agree to help the EPA in the task of pre-investigation for contained-nitrogen pollution wastewater and have willingness to cooperate the subsequent evaluation. It will help EPA to promote the set up of ammonia-nitrogen effluent standard. The project has finished the investigations of Effluent Standard including average standard, Effluent Standard of heavy metals, suspended solid standard of stone industry and silicon dioxide industry, color treatment technology of textile industry and wastewater control of funeral industry for the reference of amending Effluent Standard in the future.
