Abstract
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.
Highlights
This dataset provides detail information on the analytical methods of organophosphate esters (OPEs) in sludge samples, including the sample preparation, ultra-high performance liquid chromatography-tandem mass spectrometric (UPLC-MS/MS) analysis, quality assurance and quality control (QA/QC)
The concentration of target OPEs was measured by using an UPLCMS/MS (Ultimate 3000, Thermo Scientific, USA) system equipped with a triple quadrupole mass spectrometer (TSQ Endura, Thermo Scientific, USA)
High concentration levels of OPEs were found in the dewatered sewage sludge because of the adsorption on the activated sludge during the wastewater treatment process [4]
Summary
Degradation of organophosphate esters in sewage sludge: Effects of aerobic/anaerobic treatments and bacterial community compositions. Article history: Received 25 January 2018 Received in revised form 8 February 2018 Accepted 12 February 2018 Available online 16 February 2018 abstract This dataset provides detail information on the analytical methods of organophosphate esters (OPEs) in sludge samples, including the sample preparation, ultra-high performance liquid chromatography-tandem mass spectrometric (UPLC-MS/MS) analysis, quality assurance and quality control (QA/QC). To investigate the variation of bacterial community compositions, principal components analysis (PCA) was provided based on the high-throughput sequencing These data would be useful for clarifying the removal of OPEs under aerobic and anaerobic conditions.
