摘要

摘要: 以草酸和FeSO₄7H₂O为原料，利用液相沉积法对玄武岩纤维（BF）进行表面改性，以SEM、EDS、XPS、接触角分析仪和Zeta电位测试仪研究BF改性前后的微观形貌、元素组成、表面亲水性和电负性等性能。以枯草芽孢杆菌在不同的生长环境中的生长曲线来判断BF改性前后的生理毒性，以纯菌吸附实验和活性污泥固定实验考察有机铁改性玄武岩纤维（MBF）对微生物附着行为的影响。结果表明：MBF的亲水性和电负性得到明显改善，MBF的水接触角由89.71°降至为56.74°，表面Zeta电位由-18.53 mV提升至-5.03 mV； MBF对细菌的生长无抑制作用，不存在生理毒性；在12 h后MBF表面固定的微生物量可达27.91 gm^-2，表明有机铁改性BF有助于促使更多的生物量附着在载体表面，进而有利于提高载体的污/废水处理效果。

Abstract: The basalt fiber (BF) was modified with oxalic acid and FeSO₄7H₂O as the raw materials by liquid phase deposition method. The basalt fibers before and after being modified were characterized by SEM, EDS, XPS, contact angel analyzer and Zeta potential analyzer to observe the micro-morphology, elemental composition, hydrophilic and electronegativity. The toxicity of basalt fiber was evaluated by the growth curves of bacillus subtilis in different environment and the impacts of basalt fiber modified with ferric oxalate (MBF) on microorganism adhesion were evaluated by pure adhesion and activated sludge immobilization tests. The results show that the hydrophilic and electronegativity are significantly improved, the water contact angle of MBF decreases from 89.71° to 56.74° and the Zeta potential of MBF increases from -18.53 mV to -5.03 mV by comparison with BF. The MBF do not inhibit bacteria growth and possess no bacterial toxicity. The amount of sludge immobilized onto MBF is 27.91 gm^-2 after 12 h, indicating that ferric oxalate could promote more biomass adhering on MBF surface, thus being favor to the improvement of the effect of waste water treatment.
