Abstract Waste incineration is one of the important sources of PM_2.5. At present, there is no control unit for the effective removal of PM_2.5 in the flue gas system. In this paper, the removal effect of several filter media on PM_2.5 produced by the combustion of three kinds of organic solid wastes, namely sawdust, pork and sludge, was studied. These filter media are polyester knitting fabric, polytetrafluoroethylene (PTFE) fabric, polyvinylidene fluoride (PVDF) micro-filtration membranes, graphene and their combinations. The combination of PTFE fabric and PVDF micro-filtration membrane has the best filtration effect on PM_2.5 produced by sawdust burning, which can reach 97.45%. The filtration effect of double layer PVDF micro-filtration membrane on PM_2.5 of pork and sludge burning are 99.39% and 98.03%, respectively. According to the experimental results and SEM-EDS analysis, PVDF micro-filtration membrane has a high selectivity retention effect on particles made of C. The combined use of filter can greatly improve the filtration efficiency of PM_2.5. However, double-layer filtration may increase resistance, which is not conducive to a large number of exhaust gases for dust treatment.

Key words： PM_2.5 organic solid waste filter medium filtration performance
