固定化光合细菌处理豆制品废水产氢研究

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％。

Hydrogen production from soybean wastewater by Immobilized Photesynthetic Bacteria

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%.
