In this study, the degradation of organophosphate esters (OPEs) in sewage sludge with aerobic composting and anaerobic digestion was investigated. The total concentrations of six OPEs (ΣOPEs) in the whole treatment process reduced in the order of anaerobic digestion combined with pig manure (T3) > aerobic composting combined with pig manure (T1) > aerobic composting (T2) > anaerobic digestion (T4). The addition of pig manure significantly enhanced the removal rate of OPEs in both aerobic and anaerobic treatments. The abundance and diversity of bacterial community reduced after the treatment process. Shannon index, principal component analysis, network analysis, and heat map further confirmed the variation of bacterial community compositions among different treatments. Five genera (i.e., Flavobacterium, Bacillus, Alcaligene, Pseudomonas, and Bacillus megaterium) might be responsible for the degradation of OPE compounds in sewage sludge.
在本研究中，研究了好氧堆肥和厌氧消化处理污水污泥中有机磷酸酯（OPEs）的降解情况。在整个处理过程中，六种 OPEs（ΣOPEs）的总浓度按以下顺序降低：与猪粪结合的厌氧消化（T3）＞与猪粪结合的好氧堆肥（T1）＞好氧堆肥（T2）＞厌氧消化（T4）。添加猪粪显著提高了好氧和厌氧处理中 OPEs 的去除率。处理过程后，细菌群落的丰度和多样性降低。Shannon 指数、主成分分析、网络分析和热图进一步证实了不同处理中细菌群落组成的变化。有五个属（即黄杆菌属、芽孢杆菌属、产碱杆菌属、假单胞菌属和巨大芽孢杆菌属）可能负责污水污泥中 OPE 化合物的降解。
