Food-waste recycling wastewater (FRW) contains high particulate organic materials (POM) cause a serious drawback for the use of high rate anaerobic reactors [1]. To enhance the anaerobic digestion process, the effects of changing hydraulic retention time (HRT, 1-3 days), pH (4-6) and temperature (T, 25-45℃) on the efficiencies of bacterial hydrolysis of POM treating FRW was investigated by using response surface methodology (RSM). The maximum hydrolysis efficiency was estimated as 47% reduction of VSS when (HRT), pH and (T) were at 3 days, 6.0 and 45℃, respectively. To determine the bacterial community structures, denaturing gel gradient electrophoresis (DGGE) analysis targeting the bacterial 16S rRNA genes from reactor samples of 16 experimental trials carried out. Lactobacillus amylovorus appeared to be dominant species to hydrolysis of POM in the FRW. BMP test was conducted to compare the effect of the hydrolysis optimization with the raw FRW. The results indicated that methane yields of raw FWR wastewater and effluent of the hydrolysis reactor were 0.635 and 0.988 L CH4/g VSreduction, respectively.
