| 中文摘要 |
| 以海藻酸钠做包埋材料制备的固定化光合细菌,可以在不同浓度豆制品废水中进行光照放氢。豆制品废水COD浓度在7560—12600mg/L时,可以维持稳定产气260h以上,平均产气率为146.8-351.4ml/(L·d),气体中H2含量在60%以上,废水COD去除率为62.3%─78.2%;当废水COD浓度在1260─5040mg/L时,可以维持产气93h,平均产气率为120.7─140.oml/(L·d),气体中H2含量在75%以上,废水最终COD去除率为41%─60.3%。 |
| 英文摘要 |
| This paper presents the results of hydrogen production from soybean wastewater by immobilized photosynthetic bacteria(IPSB).The results showed that the IPSB in sodium alginate could produce hydrogen from a wide range of the concentrations of soybean wastewater.When the concentrations of wastewater ranged from 7560 to 12600 mgCOD/L,the IPSB could maintain stable hydrogen production for 260 hours,with an average gas production rate of 146.8—351.4 ml/(L·d),a hydrogen content of above 60% in the gas,and a COD removal of 62.3%—78.2%. When the concentrations of wastewater ranged from 1260 to 5040 mgCOD/L,the IPSB could maintain arable hydrogen production for 93 hours,with an average gas production rate of 120.7—140.0 ml/(L·d),a hydrogen content of above 75% in the gas,and a COD removal of 41%—61.3%. |
