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％。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 of41 %-61. 3%.
