摘要: 将广州城市污泥与稻草进行翻堆、接菌翻堆、连续通气和间歇通气4种方式的堆肥,应用GC/MS技术对堆肥中6种属于USEPA优控污染物的邻苯二甲酸酯化合物(PAEs)进行分析,探讨堆肥产物中PAEs的含量分布以及不同方式堆肥对PAEs的降解效果.结果表明,4种方式堆肥中PAEs总含量(∑PAEs)在9.815~17.832mg·kg-1之间,依次为翻堆(17.832mg·kg-1)>接菌翻堆(13.927mg·kg-1)>间隙通气(10.765mg·kg-1)>连续通气(9.815mg·kg-1).堆肥中PAEs以邻苯二甲酸正二辛酯(DnOP)为主,占∑PAEs的82.2%~89.6%.不同方式堆肥中∑PAEs的降解率为连续通气(45.71%)>间隙通气(40.46%)>接菌翻堆(22.97%)>翻堆(1.37%)(平均降解率为27.63%),其中邻苯二甲酸二乙酯(DEP)、邻苯二甲酸正二丁酯(DnBP)和邻苯二甲酸丁基苄基酯(BBP)的降解率分别为95.76%~98.68%、79.56%~99.46%和87.42%~98.42%;但邻苯二甲酸二甲酯(DMP)和邻苯二甲酸正二辛酯的含量反而增加.邻苯二甲酸(2乙基己基)酯(DEHP)在所有堆肥中均未检出.

Abstract: Four composting treatments for municipal sludge and rice straw were carried out, which included turning composting, inoculation-turning composting, continuous aeration, and intermittent aeration. GC/MS determination of phthalic acid esters (PAEs) in different composted composts showed that the total contents of six PAEcompounds (∑PAEs) ranged from 0.980~17.832 mg·kg-1, decreasing in the order of turning composting (17.832 mg·kg-1) >inoculation-turning composting (13.927 mg·kg-1) >intermittent aeration (10.765 mg·kg-1) > continuous aeration (9.815 mg·kg-1). DnOP was dominated in the composts. The degradation rate of ∑PAEs after composting was 1.37~45.71% (mean27.63%), and that of diethyl phthalate (DEP), di-n-butyl phthalate (DnBP) and butylbenzyl phthalate (BBP) was 95.76~98.68%, 79.56~99.46% and 87.42~98.42%, respectively. The concentration of di-n-octyl phthalate (DnOP) was increased in the composts. Aeration-composting, and continuous aeration composting in particular, was more efficient than other treatments to degrade PAEs in municipal sludge.
