Abstract

The technologic condition of immobilization of photosynthetic bacteria and its treatment for the wastewater of bean products were studied.The results showed that 10% PVA,4% SiO_2,0.15% sodium alginate and 30% cell suspension were the optimal immobilization conditions of PSB.Under the condition of aerobic culture in darkness,100 mL inventory/250 mL flask,pH 8.0 and 20% inoculation amount,the COD_(cr)() of the wastewater by immobilization of PSB was reduced by 91% after 120 h treatment.
