Anaerobically treating wide range of waste biomass materials

摘要: The multistage anaerobic treatment for biomass, with simultaneous recovery of biogas, comprises mechanically separating contaminants followed by a preliminary stage mechanical breakdown; disrupting the cells ultrasound before and/or after later stages; microbiologically pre-hydrolysing; and conditioning hydrolysing, separate sedimented solid material floating light material. Heating pH adjustment are methanisation (i.e. digestion), solids being treated separately. separated digestion residues composted aerobically, process water treatment. Also claimed is plant above process, in which hydrolysis reactor rectangular base sloping, has sludge extraction screw over length sump.
