Abstract :
A response surface regression analysis (RSREG) were employed to determine the optimum conditions and interaction effects of chloroform and acetylene in the anaerobic digestion process of the food origin wastes. Acetylene promoted the inhibition efficiency (p < 0.01) more effectively than chloroform (p > 0.05). Chloroform had significant effect on enhancing the production of propionic acid and a minimum molar ratio of acetic acid to propionic acid of 0.707 was reached with the chloroform concentration of 9.24 mg/kg and acetylene concentration of 4.0 times 10-3 (v/v). Moreover, biological inhibition technology practice at landfills was feasible and the environmental damage was negligible, according to the analysis and experimental results.
