In view of complex and multi-factor characteristics of anaerobic digestion treatment for municipal solid waste, orthogonal experiment was used to select the best technical conditions considering TS, temperature and C/N ratio. The results showed temperature had the biggest, followed by TS, and C/N ratio had minimum effect on digestion process. Besides, high TS can bring high gas quantity whereas VFA was also high which may hinder the digestion process.
