Abstract: Cellulase,laccase and α-amylase were used to hydrolyze kitchen waste mixture. Amount and rate of enzymes, pH of kitchen waste mixture solution, hydrolysis temperature and time were tested to check hydrolyzation. The results showed that kitchen waste hydrolysis was accelerated under above enzymes, DE and sCOD increased, meanwhile, TS were markedly reduced. Orthogonal experiment showed that DE and sCOD of hydrolysis solution were 38.6% and 23.2 g/L, respectively, TS reduced by 28.63% than that of blank controlled kitchen waste mixture.

Key words: enzyme, kitchen waste, hydrolysis, DE value
