            Abstract A  five-compartment  purification  tank  reactor  (FcPTR)  with  the  same  volume  as  three-compartment
            septic tank (TcST) was constructed to address the problem of substandard effluent from TcST, and a study of the
            start-up  characteristics  of  FcPTR  and  TcST  for  treating  actual  domestic  wastewater  was  conducted.  The  results
            showed that the removal rates of FcPTR and TcST of COD  decreased to 44% and 31%, respectively, on the 13th
                                                              Cr
            day (HRT is 80 h). On the 46th day (HRT is 36 h), the removal rates of FcPTR and TcST of COD increased to
                                                                                                 Cr
            86% and 61%, respectively, by reducing HRT. On the 46th day, pH of FcPTR anaerobic fold 1 zone was generally
            larger than that of anaerobic fold 2 zone, and the acid to basic ratio of FcPTR anaerobic zone was 0.12-0.20, which
            had better acidification and methanation separation characteristics. On the 46th day, the filler and sludge in FcPTR
            were observed by sweeping electron microscopy, the morphology of biofilm on the fillers was successful, and the
            microorganisms in the sludge were mainly short bacilli and spherical bacteria. Research shows FcPTR had a better
            treatment effect than TcST, and COD effluent reached the Class Ⅰ A of Discharge Standard of Pollutants for
