摘要： A method of biogas production enhancement for an anaerobic digestion process is provided. The method of biogas production enhancement uses a cationic polymer to improve the efficiency of converting organic waste into biogas, such as methane containing gas. The cationic polymers typically used are a copolymer of acrylamide / dimethylaminoethyl acrylate methyl chloride. Biochemical methane potential (BMP) assay was carried out with varying amounts of cationic polymer. The results indicated much earlier and higher biogas production rates compared to the control and increasing COD removal efficiency. Further, the low concentration of cationic polymer additive can condition the charges on the surface of the anaerobic microbes and enhance synergy of the microbe community resulting in better kinetics of hydrolysis, acidogenesis and methanogenesis. Further, the low concentration of the cationic polymer can enhance the tolerance of the microbes to the toxicity of the wastewater by conditioning the microbial community.
