聚丙烯酰胺(PAM)广泛用于油田的三次采油,由此产生了大量的含聚废水。由于PAM的高分子特性,使得含聚废水难以处理。基于生物膜法,利用Circox反应器对模拟含聚废水进行处理,经过93 d的运行,反应器出水水质稳定,对PAM、COD、TN的去除率分别达到65.7%、69.7%、54%。Circox生物膜反应器处理含聚废水在技术上是可行的。 Polyacrylamide (PAM) is widely used in the tertiary recovery of oil fields, resulting in a large amount of polycyclic waste water. Due to the high polymer properties of PAM, poly-containing wastewater is difficult to handle. Based on the biofilm method, the wastewater containing simulated wastewater was treated by Circox reactor. After 93 days of operation, the effluent quality of the reactor was stable, and the removal rates of PAM, COD and TN were 65.7%, 69.7% and 54% respectively. Circox Biofilm Reactor is technically feasible to treat polymer-containing wastewater.
