  通過活性炭工藝去除痕量有機污染物

  在活性炭處理過程中痕量有機污染物的去除值,根據活性炭的比重增加對數據進行分類。通常,活性炭對大多數痕量有機污染物表現出顯著的去除性能,包括反滲透膜無法適當保留的物質,例如DCM,DCE,BTA和TCM。另一方面,活性炭無法如預期那樣去除鹽分,這反映在原水和加工/處理后水的可比電導率中。不過,總體而言,活性炭操作比反滲透膜所需的能源少。活性炭的壓降低于<1bar,其去除值通過改變活性炭填充而變化。通過增加活性炭過濾的運行時間,可以觀察到去除率從81%降低到50%(第二次填充)和70%降低到93%(第一次填充)。因此,差異可能與兩種交流電荷之間的差異以及采樣和分析誤差有關,這些誤差在某種程度上通過首次填充的兩次測量得到了記錄。對于二甲雙胍,發現在特定負載下去除率從63%到97%發生了非系統性變化。使用純凈的活性炭,沿過濾器深度觀察到大多數痕量有機污染物的濃度分布降低(去除趨勢增加參見圖2)。
