| 中文摘要 |
| 水葫芦强比预处理后再进行两相厌氧生物处理,其平均产气量可达134L/kg鲜水葫芦,较之单纯两相厌氧处理,产气量提高40%;气体中甲烷含量为75.1%左右;系统出水CODCr320mg/L左右,SS在40mg/L左右。在系统稳定运行过程中,产酸相处于酸化状态。 |
| 英文摘要 |
| In this paper,diphas fermentation of water hyacinth pretreated with dilute sulphuric acid was studied.Experimental results demonstrated that specific biogas yield of 134 litre Per kilogram fresh water hyacinth was obtained with methane content of biogas about 75.l%.Effluent CODCr,SS were less than 320 mg/L,40 mg/L respectively.And microbiologlcal mechanism was also studied. |
