Abstract

Abstract: Based on the gas production experiment of sludge quantity， standing time and before and after impurity removal， combined with SEM， particle size analysis， element analysis and microbial community analysis， the composition and law of gas production were analyzed to study gas production mechanism. The experimental results show that the gas produced by the sludge is composed of H₂， CO₂ and a small amount of CH₄. The gas production is proportional to the amount of sludge and the standing time. The mechanism of gas production is that fermentation and hydrolysis bacteria produce H₂ and CO₂ in the metabolic process， and produce acidic substances which can corrode the protective film on the surface of aluminum alloy and form holes. Moisture enters the interior of particles along the holes and reacts with the alloy to produce hydrogen. H₂ and CO₂ provide metabolic materials for Methane archaea in sludge to produce CH₄.

Key words: microorganism; hydrogen; methane; carbon dioxide; aluminum alloy; sludge
