Abstract:研究采用本课题组研发的亲电改性聚乙烯为悬浮生物膜载体,构建移动生物膜与活性污泥复合工艺(integrated free-floating biofilm and activated sludge,IFFAS),对东北某工业园区污水处理厂的污水处理进行现场中试.结果表明,当进水ρ(COD)、ρ(NH3-N)、ρ(TN)分别为139 ~741,19.3 ~44.9,29.6 ~ 148.6 mg/L时,改性载体在10d左右即可完成挂膜;中试IFFAS工艺稳定运行阶段,出水COD、NH3-N、TN的平均去除率分别高达88%、97%、80%,出水浓度分别为36 ~48,0.1 ~0.9,5~14.3 mg/L,达到GB 18918-2002《城镇污水处理厂污染物排放标准》一级A排放标准.出水水质明显优于污水处理厂原有A2/O工艺出水,说明以亲电改性聚乙烯为载体的IFFAS工艺可显著提高净化污水的能力.
