Abstract

Graphical abstract: Highlights: Composting of 4-nonylphenol-contaminated river sediment was studied. Inocula of Phanerochaete chrysosporium ( Pc ) could accelerate 4-NP's degradation. 4-NP contents in sediment were negatively correlated with Pc 's laccase actives. Pc increased the activities of catalase and polyphenol oxidase in the sediment. Composting time was reduced by inocula of Pc into 4-NP contaminated sediment. Abstract: A composting study was performed to investigate the degradation of 4-nonylphenol (4-NP) in river sediment by inoculating Phanerochaete chrysosporium ( Pc ). Pc was inoculated into composting Reactor A, C and D, while Reactor B without inocula was used as control. The results showed that composting with Pc accelerated the degradation of 4-NP, increased the catalase and polyphenol oxidase enzyme activities in contaminated sediment. The dissipation half-life (t1/2 ) of 4-NP in Reactor A, C and D with inocula of Pc were 2.079, 2.558, 2.424 days, while in Reactor B without inocula of Pc it was 3.239 days, respectively. Correlation analysis showed that the contents of 4-NP in sediment in Reactor A and D were negatively correlated with the actives of laccase, whereas no obvious correlation was observed in Reactor B and C. All these findings also indicated that Pc enhanced the maturity of compost, and the best composting C/N ratio was 25.46:1.
