Abstract:	DMSO在工業應用相較於乙醇具有較高的安全性，且因為具有高沸點的特性，更是一種適合回收再利用的環保型溶劑，且價格較為低廉，因此DMSO被大量的使用在各種工業。DMSO具有很高的滲透壓，且對生物具有毒性，隨著DMSO的大量使用，使得廢水中含有殘留的DMSO，若不加以處理DMSO又會被厭氧分解還原成具有惡臭的物質－二甲基硫(Dimethyl Sulfide, DMS)，其含量在低濃度時即有明顯臭味產生，極容易超過臭味標準。因此，若能開發一套解決廢水中DMSO的處理技術，同等於防止其還原成DMS，造成光電業V DMSO (dimethyl sulfoxide) is a useful and inexpensive environment benign solvent easy to recycle. Its industry-wide adoption has revealed an odorous problem to the industrial parks and their adjacent residential areas due to its decomposition product, DMS
