摘要
针对苯酐、邻苯类增塑剂废水浓度高和难降解物质浓度高的特点,提出了物化预处理—生物流化床—厌氧生化—活性污泥生化的废水处理工艺,可使处理后水质COD达到60 mg/L以下,达到循环回收利用的目的。
Based on the characteristics of high comcentration and high concentration of difficult decomposites of phthalic anhy dride and phthalate plasticizers wastewater treatment process of physical and chemical pretreatment - biologi- cal fluidized bed - anaerobic biochemical - aerobic biological was presented, which can enable the treated water quality of COD below 60 mg/L and achieve the purpose of recycling used.
