利用好氧薄膜生物處理系統(AMBR) ，再使用離子交換進行後處理，探討去除磷之成效。該MBR進流流速為10 LMH，好氧槽體體積為0.66 升。使用介面活性劑沖洗含柴油之土壤，並將該溶液在不同階段加入進流水。由結果進行比較AMBR的有機物和磷之去除率及加入柴油降解細菌後的影響。這項研究發現沖洗柴油污染之土壤的溶液，可被利用MBR處理其溶液以及由MBR 之滲透進行回收磷。結果顯示添加柴油降解菌及逐步增加柴油之介面活性劑濃度進行穩定及觀察然而COD 之去除率仍可高達98.5％。以批次實驗使用Purolite A500 樹脂去除由MBR 處理後之含磷出流水。由結果發現，吸附等溫線其R2值分別範圍從0.9683到0.9994 和0.9193 到0.9873，確定兩者的Langmuir 和Frendlich 吸附模型。然而，Langmui模型更適用於實驗數據略高於Freundlich模型。在pH 9 使用1.2 g 樹脂/升。每克Purolite A500 樹脂單層吸附容量的最大值為5.59 毫克，。在此批次實驗中以含 NaCl 3％ 的溶液（重量/ 體積）之溶液進行有效脫附。在有氫氧化鈉的溶液時再生的時間較溶液中沒氫氧化鈉快1.25 倍的時間。在這脫附過程中，在0.25M CaCl2、pH11 的條件進行脫附磷，而其最高效率為96.71%。 Removal of phosphorus was investigated using an aerobic membrane bioreactor(AMBR) with ion-exchange as a post-treatment. The MBR was operated at flux 10 LMH witha 0.66 liter aerobic MBR unit. Specific amounts of soil flushing liquid containing diesel andsurfactant were added to the synthetic wastewater at different periods of time. The organic andphosphorus removal performances of AMBR were investigated by comparing the results beforeand after adding diesel oil-degrading bacteria. This study revealed the feasibility of dieselcontaminatedsoil flushing liquid treatment using MBR as well as the protocol of phosphorusrecovery from MBR permeate. The results showed that a stable COD removal up to 98.5% wasobserved after adding bacteria while the step-wise concentration increase of diesel-surfactantflushing liquid in feed water was carried out. Phosphorus was removed from permeate usingPurolite A500 resin through batch experiments. The result found that the adsorption isothermsatisfactorily fitted to both the Langmuir and Frendlich adsorption models determined by R2that ranges from 0.9683 to 0.9994 and 0.9193 to 0.9873, respectively. However, Langmuirmodel fitted better with the experimental data slightly than the Freundlich model.The maximum value of adsorbed monolayer capacity was 5.59 mg per gram of Purolite at pH9 with 1.2 g resin/L. Regeneration was effectively desorbed using a solution containing3% (w/v) NaCl solution in the batch experiments. Percentage of phosphorus regeneration werefound the same value considering the regeneration time; and at the presence of NaOH canregenerate phosphorus faster than the absence of NaOH condition by 1.25 times. Desorbedphosphorus was recovered by precipitation process using CaCl2, the highest efficiency obtainedwas 96.71 % at 0.025 M CaCl2 and pH 11.
