Anaerobic digestion (AD) is one of the most significant processes for treating fecal sludge. However, a substantial amount microplastics (MPs) have been identified in septic tanks, and it remains unclear whether they impact resource treatment feces. To investigate this, polyethylene terephthalate (PET) was used as an indicator MPs to study their effect on anaerobic sludge (FS). Two systems were developed: FS mono-digestion co-digestion with granular The results indicated that effects PET varied between two systems. inhibited volatile fatty acid synthesis both systems, but inhibition period differed. During mono-digestion, slightly increased gas methane production, contrast system, where reduced production by 75.18%. Furthermore, soluble chemical oxygen demand ammonia nitrogen concentrations while blocking phosphorus release, whereas system showed opposite effects. Ultimately, choice method crucial utilization tank sludge, AD cannot be ignored.
