摘　　要：为解决城市黑臭水体的问题,构建基于玄武岩纤维(BF)仿生载体、微生物菌剂和曝气复氧净化黑臭水体的组合工艺,对黑臭水体净化效能进行试验研究。结果表明:BF仿生载体、微生物菌剂和曝气复氧三者相结合对黑臭水体具有良好的净化效果。经过28d的平稳运行,COD、NH+4-N和TP去除率分别为75.1%、99.4%和94.2%。经预挂膜处理的BF仿生载体在曝气复氧条件下,达到相同净化效果所需时间更短。同时BF仿生载体可有效降低水体浊度,对水体中游离微生物具有良好的吸附和富集作用,其吸附的微生物数量最高为3.57×10^7CFU/g。To solve the problem of black-odorous waterbodies, the black-odorous water purification effect based on the combination of basalt fiber (BF) biomimetic carrier, microbial agent and aerated oxygenation was studied in this work.The results showed that the combination of BF biomimetic carrier, microbial agent and aerated oxygenation had a good purification effect on black-odorous water.After a smooth operation for 28 days, the removal efficiencies of COD, NH + 4-N and TP were 75.1%, 99.4% and 94.2%, respectively.Interestingly, the pre-coated membrane BF biomimetic carrier could achieve the same purification effect faster under aerated oxygenation,which could also effectively reduce turbidity of water and had good adsorption to free microorganisms with a high adsorption capacity of 3.57×10 7 CFU/g.
