摘要

本文选取生态碳纤维为研究对象,分别从其吸附性能、挂膜情况、去氮除磷效果等方面进行了研究。研究表明:碳纤维的吸附功能基本在试验60h左右达到最大,之后趋于稳定,对NH~+_4-N、TP的去除率分别为29.7%、26.7%;将碳纤维放置在含有污泥团的水中72h后可形成成熟的生物膜,生物膜上主要的附着物为耐毒的菌胶团,此外还有一部分轮虫、变形虫、线虫等,在吸附与生物膜的共同作用下,碳纤维对NH~+_4-N、TP的去除率分别达到72.7%、56.3%。碳纤维既可以作为生物膜法的载体材料也可单独应用于水体的修复与治理中,具有良好的推广应用前景。
        In this paper, ecological carbon fiber was selected as the research object, and its adsorption performance, film formation and nitrogen and phosphorus removal effects were studied respectively. The results showed that the adsorption function of carbon fiber reached the maximum basically in about 60 hours, and then tended to be stable. The removal rates of NH~+_4-N and TP were 29.7% and 26.7% respectively. The mature biofilm can be formed after carbon fiber is placed in water containing sludge aggregates for 72 hours. The main attachments on the biofilm are toxic-resistant micelles. In addition, there are some rotifers, amoeba, nematodes, etc. Under the combined action of adsorption and biofilm, the removal rates of NH~+_4-N and TP by carbon fiber reach 72.7% and 56.3% respectively. Carbon fiber can be used as a carrier material for biofilm process and can also be used alone in the restoration and treatment of water bodies, thus having good popularization and application prospects.
