چکیده انگلیسی
In order to maximise the efficiency of biogas desulphurisation and reduce the oxygen cost during microaerobic digestion, it is essential to know how the process occurs. For this purpose, a reactor with a total volume of 266Â L, treating 10Â L/d of sewage sludge, was operated with 25.0Â L and without headspace. Under anaerobic conditions, the H2S concentration in the biogas varied between 0.21 and 0.38%v/v. Next, O2 was supplied from the bottom of the reactor. At 0.25-0.30 NLO2/Lfed, the biogas was entirely desulphurised, and its O2 content remained below 1.03%v/v, when the digester had 25.0Â L of gas space. However, with almost no headspace, the H2S content in the biogas fluctuated from 0.08 to 0.21%v/v, while the average O2 concentration was 1.66%v/v. The removed H2S accumulated in the outlet pipe of the biogas in the form of S0 due to the insufficient headspace.
