Abstract

In this study, X-ray photoelectron (XPS) was used to investigate the sulfur existing forms and transformation of dewatered sewage sludge which collected form a wastewater treatment plant using A2/O process in different seasons. The S2p spectra obtained curves were resolved into 6 peaks: sulfate-S(170.0±1.0 eV), sulfone-S(168.0±0.5 eV), sulfoxide/sulfite-S(166.0±0.5 eV), thiophene-S(164.1±0.2 eV), sulfide-S(163.3±0.4 eV) and mercaptan-S(162.2±0.3 eV). The results show that the existing forms of sulfur can mainly be divided as inorganic-S and organic-S, the content of sulfur in the sewage sludge sample increased with the environmental temperature rising. The content of each component was closely related to the environmental temperature, inorganic sulfur decreased with the increasing environmental temperature, while organic sulfur increased with the raise of environmental temperature and reached the maximum value in July.
