Sewage treatment filler can improve the effect of sewage treatment, but its clogging problem will reduce the treatment capacity and deteriorate the operating conditions, which needs to be solved urgently. In order to improve the anti-clogging ability of sewage treatment filler, this paper reviewed the relevant research on the clogging of sewage treatment filler. The formation mechanism of clogging for sewage treatment filler was summarized from the aspects of filler characteristics, application scenarios, material classification, clogging characteristics, development mechanisms and influencing factors. Seven common control measures for clogging of sewage treatment filler were discussed from three aspects:pre-event,in-event and post-event. According to current studies, the research suggestions on clogging formation mechanism, clogging control measures and filler design optimization were proposed to provide support for the subsequent research and technology development of sewage treatment fillers, and improve the application of sewage treatment fillers.
