【摘要】 采用新型工艺UV/微曝气对水中内分泌干扰物4-叔丁基苯酚(BP)进行降解研究.结果表明,UV/微曝气是一种高级氧化法,可以有效去除水中BP;UV/微曝气联用工艺降解BP受本底TOC值、BP初始浓度值、UV光强以及溶液初始pH影响较大.随着TOC值的降低,BP降解速率k1迅速增加;随着光强的增大,BP的降解速率呈线性增长;在189~410μg/L浓度范围内,k1随着BP浓度的增大而逐步增大,在410~971μg/L浓度的范围内,k1随着浓度的增大而逐步降低;pH 2.77~4.01范围内UV/微曝气对BP降解速率较大,pH 4.70~8.16范围内UV/微曝气对BP降解速率较低.更多还原

【Abstract】 The removal performances of EDCs 4-tert-butylphenol（BP） in water using a new process UV/micro-aeration was introduced.The results show that UV/micro-aeration process is also an advanced oxidation and BP can be effectively degraded by UV/micro-aeration process;the degradation of BP by UV/micro-aeration process is greatly influenced by TOC value,BP initial concentrations,intensity of UV radiation,and initial pH of solution.The k₁ value of BP degradation increases with TOC values decreasing,or with intensity of UV radiation increasing.The effect of different BP initial concentrations on removal of BP has also been investigated.The k₁ value of BP degradation increases with increasing BP initial concentrations in the range of 189～410（μg/L）,while decreases with increasing initial BP concentrations in the range of 410～971（μg/L）.The degradation of BP has been investigated under UV/micro-aeration over a wide pH range（2.77～8.16）,and BP degradation rate in UV/micro-aeration process was significantly enhanced by the initial pH in the range of 2.77～4.01,while decreases in the pH range of 4.70～8.16.更多还原
