摘要：对松香深加工废水难治理的原因进行了重点分析,并提出了"预处理—生物接触氧化—混凝"组合工艺处理松香深加工废水。采用活性炭和Fe-C内电解2种预处理方式,COD去除率可达18%左右,提高了松香废水的可生化性。经预处理后的松香废水采用二段活性污泥处理后,COD降至358 mg/L。松香生化出水常规混凝剂(芬顿、PFS和PACF等)难于降解,而采用自主研发的F1混凝剂可明显降低废水中有机污染物。当F1混凝剂的质量浓度为4 g/L时,废水中的COD降至69.8 mg/L,与常规混凝剂相比具有明显的优势。为松香类废水的处理提供了一条切实可行的路线。
The reasons for the difficult treatment of rosin deep processing wastewater are analyzed. A combined process of pretreatment-biological contact oxidation-coagulation is proposed to treat rosin deep processing wastewater. The removal rate of COD is about 18% and the biodegradability of rosin wastewater is improved by the pretreatment of activated carbon and Fe-C internal electrolysis. After the pretreated rosin wastewater is further treated with second-stage activated sludge,COD is decreased to 358 mg/L. Rosin biochemical effluent coagulant（ Fenton,PFS and PACF,etc.） is difficult to degrade. By contrast,the self-developed coagulant（ F1） can significantly reduce organic pollutants in wastewater. When the mass concentration of F1 coagulant is 4 g/L,the COD in wastewater is decreased to 69. 8 mg/L,which has obvious advantages compared with conventional coagulant. It provides a practical route for the treatment of rosin wastewater.
