In this paper, biodegradation experiments of 9 PAEs were carried out with acclimated inoculation The results showed that biodegradation rate constants(kb) of 9 PAEs decreased, and biodegradation halflife time(t1/2) increased,with the increase of alkyl chain length。降解半衰期與烷基鏈長(zhǎng)度同時(shí)存在相關(guān)，t1/2= (r=)。9種鄰苯二甲酸酯化合物的模擬曝氣降解研究摘要： 鄰苯二甲酸酯是一類全球性的重要污染物，本課題進(jìn)行了9種鄰苯二甲酸酯化合物的模擬曝氣生物降解行為研究。結(jié)果表明，鄰苯二甲酸酯的降解速率常數(shù)（kb）與其烷基鏈長(zhǎng)度之間存在良好的相關(guān)性，lnkb= (r=)。 關(guān)鍵詞： 鄰苯二甲酸酯 模擬曝氣法 生物降解Aerobic Degradation of 9 Phthalic Acid EstersXia Fengyi1,2，Zheng Ping1，Zhou Qi2 and Feng Xiaoshan1(1 Department of Environmental Engineering,Zhejiang University,Hangzhou,310029。 There have been correlations between alkyl chain length and biodegradation rate constant or halflife time, relational equation: lnkb= (r=),
