| 摘 要： | 采用改良型的A2／O工艺试验装置进行试验，在水力停留时间为12 h、溶解氧浓度为0．5～0．8 mg／L的条件下，考察了投加改性的磁性药剂前后进、出水各污染物的变化情况。结果表明，投加改性的磁性药剂前后， COD、NH 3－N、TN、TP的平均去除率分别为68％与81％、55％与80％、51％与69％、44％与70％，较投加改性的磁性药剂前，去除率分别提高了19％、45％、35％、59％。中试结果证明，该改性的磁性药剂可以提高反应池对上述污染物的去除效果，应用前景较好。

| Abstract: | Tests were conducted using the modified A2/O process test device under the condition of hydraulic residence time of 12 h and dissolved oxygen concentration0.5 ~0.8 mg/L.The changesof pollutants in influent and effluent before and after adding magnetic medicament were studied.The results show that the average removal rate of COD, NH3 -N, TN and TP were 68% and 81%, 55% and 80%, 51% and 69%, 44% and 70%.The removal rate were increased by 19%, 45% and 35%, 59%.Test results show that the change of magnetic medicament can improve the reaction tank of the pollutant removal effect , and has a good application prospect. |
