| 中文摘要 |
| 报告了升流式固体反应器(USR)在35C条件下处理鸡粪废水的实验结果。进水COD浓度41900-61500mg/L,SS45-55g/L,SCOD为7200mg/L,总挥发酸浓度3174mg/L,pH=6.61.USR运行67d后,消化器负荷达到10.45g/(L·d),产气率为4.88L/(L·d),所产沼气中平均甲烷含量59.75%,COD去除率86.62%.在HRT5d时,计算出SRT为24.8d,SS去除率66.16%,说明USR适用于高SS含量废水的处理。 |
| 英文摘要 |
| The paper presents the result of Chicken farm wastewater anaerobic digestion in upflow solid reactor(USR) at 35℃.The in fluent concentration was as follows:COD:41900-61500 mg/L,SS:50-60 g/I-,TVA:3174 mg/L,pH=6.61.After 67 days of USR proceeding,the loading rate of USR reached to 10.45 g/(L·d), gas production rate achieved 4.88 L/(L·d),and average amount of CH4 was 59.75% in which,the COD removing rate increased to 86.62%.At 5 days of HRT,the SRT was 24.8 d,SS removing rate was 66.16%. |
