摘要
利用OxiTopBOD测试仪测定微生物耗氧量的方法,对邻氟苯酚、间氟苯酚和对氟苯酚的好氧生物降解性能进行了研究,结果表明:邻氟苯酚、间氟苯酚和对氟苯酚的耗氧生物降解速率常数分别是0.0093L·g-1·h-1,0.0133L·g-1·h-1和0.0145L·g-1·h-1.降解活性与化学结构的相关性分析表明:辛醇/水分配系数和分子连接指数是影响受试物好氧生物降解性能的两个重要因素.
By measuring the respiratory oxygen consumption, a study on the aerobic biodegradability of o-fluorophenol, m-fluorophenol and p-fluorophenol was conducted spectively. The experimental results show that the using activated sludge acclimated by themselves re- degradation rate constant is 0. 0093 L· g^-1 . h^-1, 0. 0133 L· g^-1 · h^-1 and 0. 0145 L · g^-1 · h^-1 respectively. The octanol/water partition index and molecular connectivity index are the main factors which can affect the aerobic biodegradation of fluorophenols.
