摘　　要：传统的甲醛去除方法效率低、易致二次污染,微生物法则操作复杂、易受环境影响。固定化微生物技术有生物量浓度高、处理效率高、条件简易等诸多优点。本实验对以甲醛为唯一碳源的微生物进行培养和鉴定,采用反复冻融聚乙烯醇和海藻酸钠制作包埋颗粒,评估其降解效果。在9天的降解后,经筛选培养的微生物包埋颗粒使甲醛含量降至初始值的52.1%。本研究通过固定化生物技术降解室内甲醛,在兼顾环保的同时提高了甲醛降解的效率和稳定性。Traditional formaldehyde removal techniques suffer from low efficiency and potential secondary pollution,while microbial methods can be complex to operate and environmentally sensitive.Immobilized microorganism technology offers advantages such as high biomass concentration,enhanced treatment efficiency.This experiment involved culturing microbes that utilize formaldehyde as their sole carbon source and preparing embedded particles from polyvinyl alcohol and sodium alginate through freeze-thaw cycles.It was found that formaldehyde decreased by 52.1%in 9 days.The results indicate that the immobilized microbes can effectively degrade formaldehyde.It demonstrates that immobilized biotechnology offers a promising and eco-friendly solution for formaldehyde degradation.
