摘要利用自制的微型污泥发酵装置，加入不同微生物菌剂（RW酵素剂、RW促腐剂、如金环保专用原液、如金有机肥发酵剂、金宝贝有机肥发酵剂）对污泥进行好氧发酵21天，探讨污泥中固有的壬基酚类物质在加入不同微生物菌剂发酵后的变化情况，对比分析各微生物菌剂的效果。结果表明对NP来说降解效果最好的是如金环保专用原液，其次是RW促腐剂，降解率分别为21.32%、19.04%。对NP1EO而言降解效果最好的是如金环保专用原液与RW酵素剂，降解率分别为42.04%、40.09%。对NP2EO降解效果最好的是如金环保专用原液与金宝贝有机肥发酵剂，降解率分别为48.49%、41.24%。42682

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%.
