Abstract:A batch experiment of 48days was carried out under the conditions of mesophilic (35℃) and thermophilic (55℃) by using raw chicken manure (RCM), solid part of chicken manure (SCM) and liquid part of chicken manure (LCM) to test the biogas production dynamics and potential when the seed sludge obtained from the effluent of chicken manure methane fermentation reactors under mesophilic and thermophilic conditions, correspondingly. It's worth noting that both reactors were continuously operated more than 90days, which domesticated microorganisms in the reactors adapted to the methane fermentation of chicken manure. An obvious two-stage characteristic with RCM methane fermentation biogas production simulated by Gompertz model, first order kinetics model and two-stage model under mesophilic and thermophilic conditions was analyzed. The K1 of fast biogas production stage kinetics under mesophilic and thermophilic conditions were 0.4174 and 0.2104d-1, when the methane production during fast biogas production stage took 69% and 58% of total methane production, respectively. And then it entered slow biogas production stage in 4.5 and 6.4d. The first-order kinetic rate constants of RCM and LCM mesophilic methane fermentation were 0.4177 and 0.2330d-1, which higher than those getting from RCM and LCM thermophilic methane fermentation. Thus, compared to thermophilic methane fermentation, RCM and LCM mesophilic fermentation had a faster methane production rate. But the first-order kinetic rate constants of SCM mesophilic methane fermentation was only 0.4177d-1, which lower than those getting from LCM mesophilic methane fermentation and SCM thermophilic methane fermentation. So the hydrolysis process maybe one of the main factors limiting the methane production rate of chicken manure under mesophilic condition. The first-order kinetic rate constant of SCM and LCM thermophilic methane fermentation were 0.2310 and 0.22214d-1. So SCM thermophilic methane fermentation had a faster methane production rate than LCM thermophilic methane fermentation, which saying that the hydrolysis process was not the main factor limiting the methane production rate of chicken manure under thermophilic condition. The methane production potential of RCM under mesophilic and thermophilic conditions were 212.9 and 177.4mL/gTS. Therefore, compared with those in thermophilic condition, the methane production potential and the maximum methane-producing rates were higher and faster under mesophilic condition.
