| 中文摘要 |
| 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189～410 μg/L浓度范围内，k1随着BP浓度的增大而逐步增大，在410～971 μg/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. |
| 英文摘要 |
| 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. |
