Effects of microbial inoculants on degradation of nonylphenol during sludge aerobic fermentation
Abstract Aerobic fermentation was conducted for 21 days by using homemade micro sludge composting device and adding different microbial bacteria agents (RW enzyme agent, RW promoting rot agent, Rujin special solution for environmental protection, Rujin organic fertilizer fermentation agent and Jin baobei organic fertilizer fermentation agent). The changes of nonylphenolic compounds were discussed when different microbial bacteria agent was added into sludge. Results indicate that Rujin special solution for environmental protection has the best effect for Nonylphenol, secondly is the RW promoting rot agent, degradation efficiency is 21.32% and 19.04%. The best degradation effect for NP1EO is the Rujin special solution for environmental protection and RW enzyme agent, degradation rate is 42.04%、40.09%. For NP2EO, the best one is Rujin special solution for environmental protection, and then is the Jin baobei organic fertilizer fermentation agent, degradation rate is 48.49%、41.24%.
