| 摘 要： | 利用中温厌氧消化工艺,在CSTR反应器内对畜禽粪便、污水处理厂污泥及农村生活垃圾3种原料进行联合厌氧消化试验研究,重点探讨了3种原料的配比问题。结果表明,在温度为37℃,停留时间为20 d,粪便、污泥、垃圾TS之比为6∶3∶1,容积负荷为3.61 g/(L.d)的条件下,系统稳定性和处理效果都比较理想,单位VS的产气率为0.36～0.39 L/g,VS去除率为45.1%～49.4%。

| Abstract: | In order to solve the environmental pollution problems caused by manure,sludge and rural organic waste,we studied the joint treatment on the three pollutants by mesophilic anaerobic digestion processing.The anaerobic co-digestion experiments were carried out in a continual stir tank reactor under 37 ℃,operated with a HRT of 20 d,and focused on the proportion of the mixtures ratios.The experiment results showed when livestock manure,waste activated sludge and rural organic waste have the ratio was 6∶3∶1 on the TS basis,with an OLR of 3.61 g/(L·d),the optimal operate conditions of the process were perfect in terms of the stability and performance.The volatile solids removal efficiency,specific biogas production in these conditions achieved 45.1%～49.4% and 0.36～0.39 L/g respectively. |
