| 摘 要： | 水葫芦强化预处理后再进行两相厌氧生物处理,其平均产量气量可达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。

| Abstract: | 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. |
