Studies on the effects of pretreatment on production hydrogen from municipal sludge anaerobic fermentation
Abstract: Municipal sludge was rich in organic matter, period of natural degradation was long and low efficiency, leachate would pollute underground water. In this paper, a comparative study of the ways of pretreatment with acid alkali treatment, heat digestion and ultrasonic treatment were done. The results showed that The dehydro-genase activity were increased, the SCOD (soluable chemical oxygen demand, SCOD) in-creased more than 2.47~2.83, 1.70~1.76, 2.6~ 2.77 times respectively. The hydrogen yield in-creased more than 11.5~12.2, 24.1~24.7, 34.2~ 34.9 mL.g-1 (VS) respectively. The period of pro- hydrogen was shorten to 7.5, 8.0, 6.5 d respec-tively. The degradation rate was up to 72.04%, 81.4%, 80% respectively, the methane concen-tration in the gas was close to “zero” and ul-trasonic treatment was better than others. Gompertz model curve fitting on hydrogen production was carried out. All the values of correlation factor R2 were more than 0.97.
