中文摘要 | 本研究之目的在於如何提升染整廢水廠之處理效率。該廠之廢水量約為4000CMD, 平均 COD 值為 817 mg/l。 經過生物及化學處理後, COD 值分別減至約 187 mg/l 及 101 mg/l,但是仍無法符合 87 年放流水標準,因此有提升廢水處理廠功能之需要。根據評估結 果決定以改變操作方式及加入 Fenton 程序來提昇現有功能。結果顯示,增加營養源如:氮 、磷、鐵及增加食微比( 0.32 to 1.05 kg COD/kg.MLSS.Day ), 生物單元之出流水 COD 可由 187 降至 150 mg/l。若用 Fenton 處理生物槽出流水,在 200 mg/l 之 H �� O �砥A 60 mg/l 之 Fe �杠握� pH=3.0 之條件下, 則可將 COD 從 204 mg/l 降至約 50 mg/l,由 此可知,Fenton 之效率再這方面,遠比傳統之混凝╱膠凝程序為佳。 |
英文摘要 | This paper presents an upgrading treatment of composite wastewater from a textile plant. The composite wastewater flow was around 4000 CMD and the wastewater characteristics showed an average COD of 817 mg/l. After biological and chemical treatment, the average COD's were reduced to around 187 mg/l and 101 mg/l, respectively. If compared to the new promulgated COD discharge standard of 100 mg/l here in Taiwan, the performance of this treatment system is obviously inadequate to comply with the above standard. In order to meet the regulatory requirement, the emphases of this study were placed on improving the performance of activated sludge as well as on the replacement of chemical coagulation unit by Fenton process. As a result, by increasing biological nutrient doses such as N, P, and Fe sources as well as by increasing food-to-microorganism ratio from 0.32 to 1.05 kg COD/kg MLSS.Day, the effluent COD can further drop from 187 to 150 mg/l. It was found that the initial COD of 204 mg/l contained in the biological effluent can be reduced to around 50 mg/l after one hour reaction time under the conditions of 200 mg/l of H �� O ��, 60 mg/l of Fe �杠�, and pH = 3. In comparison, it appeared that the Fenton process performs better than the chemical coagulation. |
