綠能設備結合浮水植物於淨化生活雜排水之研究

依行政院環境保護署調查，台灣約有三分之一河川受汙染，在廢水排放中生活排水量占第一，加上現今洗潔劑成分複雜而排放至河川後對河川造成優氧化現象，若想解決這問題可以從學校、家庭、工廠等單位設置簡單天然的淨水系統。本研究選用五種常見浮水植物：水萍(水樣B)、人厭槐葉萍(水樣C)、青萍(水樣D)、大萍(水樣E)、圓心萍(水樣F)做初步水質淨化處理，於容積60L 水箱注入約50L 的明道大學志強宿舍生活雜排水，在實驗組放置礫石與微氣泡，並使用太陽能供電，含對照組共A~F 六種水樣，以一年時間探討各組淨化效益。經過一年四季的實驗結果顯示，水樣C 的DO 數值最為穩定均維持在5~9mg/L；水樣B、C、E 之pH 值最穩定，都維持在6~9；水樣B~F 的EC 均維持在法規標準250~750μmho/cm；而各水樣的ORP則是維持在70 mv~145 mv。在微生物觀察中共發現37 種微生物，水樣E 種類最多共20 個物種，水樣D 最少共9 種物種，水樣B 以Spirogyra Sp.、NeospongiococcumSp.最多；水樣C 以Cocconeis Sp.最多；水樣D 以Actinastrum Sp.最多；水樣E 以Cocconeis Sp.最多；水樣F 以Closterium Sp.物種最多。本次研究希望在未來有助於水質淨化之水生植物選擇，進而提昇該區域水質亦可提供野生動物庇護，以及景觀休閒與生態教育等附加價值，讓後續從事相關工作與研究者提供有用的參考依據。

According to the Environmental Protection Administration survey, about one-third of rivers contaminated, and the wastewater living in displacement accounted for first in Taiwan, and nowadays detergent ingredient complex after discharge to river cause eutrophication phenomena, if want to solve this problem can be set up simple natural water purification systems from schools, homes, factories etc. This study selection five common floating plants: Spirodela polyrhiza (sample B), Salvinia molesta D. S. Mitchell (sample C), Lemna aequinoctialis Welwitsch (sample D), Pistia stratiotes L. (sample E), Limnobium laevigatum (samples F) to do the initial water purification process, in volume of about 60L tank injection of Sewage water 50L form dormitory in Mingdao University, place gravel and microbubbles in the experimental group, and the use of solar power, including control group (no floating plants, sample A) of six water samples A ~ F, In a year to explore each group purification efficiency. After the year's results show, the DO samples C is the most stable in water samples remained at 5 ~ 9mg/L; water samples B, C, the pH samples E of the most stable, all maintained at 6-9; water sample B ~ F of the EC regulations and standards are maintained at 250 ~ 750 μmho/cm; and each water sample the ORP is maintained at 70 mv ~ 145mv. Observation of microorganisms were found in 37 kinds of microbes, the water sample E is most up to a total of 20 species, sample D is minimum total of 9 species, samples B is Spirogyra Sp and Neospongiococcum Sp maximum; samples C is Cocconeis Sp most.; samples D is Actinastrum Sp most; samples E is Cocconeis Sp most; samples F is Achnanthes sp species most. This study is to contribute to water purification in the next selection of aquatic plants, and thus enhance the quality of the region will also provide added value to wildlife refuge, as well as landscape recreational and ecological education, so that follow-up related work and provide useful reference for researchers.
