    Abstract: 醫院廢水生物處理設施,因曝氣系統致使大量微生物逸散於周圍空氣中,對操作人員及醫院病人,附近居民之健康皆有潛在之威脅。本研究擬針對此問題加以評估探討。結果發現: (1)醫院廢水處理廠生物氣膠之主要發生源為進流口、調勻槽及曝氣槽。(2)發生源生物氣膠之平均含菌量入流口之含菌量為10/sup 3/CFU/M/sup 3/至10/sup 4/CFU/M/sup 3/,調勻槽亦為10/sup 3/CFU/M/sup 3/至10/sup 4/CFU/M/sup 3/,曝氣槽為10/sup 3/CFU/M/sup 3/至10/sup 5/CFU/M /sup 3/。(3)密閉式汙水處理廠所產生生物氣膠微生物含量遠大於比較開放式及半開放式。(4)以接觸曝氣式處理所產生之生物氣膠比活性汙泥方式處理的含量低。(5)醫院廢水採活性汙泥曝氣法其生物氣膠常見之菌種出現頻率較高者有Mold,Bacillus,Pseudomonas. spp. Serratia spp.,Klebsiella spp., Enterobacteria spp. Acinetobacter,醫院廢水採接觸曝氣設施其生物氣膠常見之菌種有Mold,Bacillus,Endococcus,(6)醫院廢水處理過程所產生之生物氣膠亦可能為院內感染之微生物發生源之一。
