O_3-BAC工艺在饮用水处理中的应用

Application of O_3-BAC process in drinking water treatment

以南方某水厂为例,探讨了O3-BAC工艺在饮用水处理中的应用。运行结果表明,O3-BAC出水p H值随运行时间的延长而下降,因此影响亚硝化作用及后期投碱量;O3-BAC工艺运行初期对CODMn的去除作用以物理吸附为主,运行后期以生物降解为主,二者均具有较好的去除效果;O3-BAC工艺应对突发性氨氮污染较滞后,但在高氨氮环境下随着运行时间的推移,对氨氮的去除效果较好。

Taking a waterworks in southern area of China as an example, the application of O_3- BAC process was discussed in drinking water treatment. The operational results indicated that O_3-BAC outflow pH was declined with the extension of operational time, therefore the nitrosation and alkalinity dosage in latter period were influenced. The removal of COD_Mn was mainly physical absorption in the initial operation of O_3-BAC process, and biological degradation in the latter operation. Both process had the satisfied removal effects. The O_3-BAC process was delayed coping with the urgent ammonia contamination. The removal effect of ammonia was good with operational time lapse in high concentration of ammonia environment.
