%X The effects of temperature, substrate concentration, pH and modification methods on the biodegradation of carriers and biofilm attachment to the carriers were investigated. The results showed that the final degradation rates of unmodified, crosslinked, and crosslinked-cationic carriers were 55.2%, 23.9%, and 20.5%, respectively. The volume of biofilm on crosslinked-cationic carriers achieved a maximum of 0.247 g·g-1. Carrier degradation supplies carbon for bacteria, which accelerate the initial degradation of the carriers, as well as improves degradation ratio of SO2-4 in wastewater by 51% at most. In addition, increasing the pH from 5.0 to 6.5 caused the final degradation rate of the carriers to decline and the biofilm volume to gradually increase.
