The Effect of Photosynthetic Bacteria on the Treatment Efficiency of High-strength Monosodium Glutamate Wastewater

Ai Cuiling(College of Civil Engineering,Fuzhou University,Fuzhou 350002,China)  
In this paper,monosodium glutamate wastewater was treated using photosynthetic bacteria in modified SBR reactor,namely added the semi-soft material in the traditional SBR reactor.This paper studied the effect of two different metabolic methods of photosynthetic bacteria on removal rate of COD and on the flocculation property of activated sludge based on the characteristic of cyto-architecture and metabolic method through enrichment separation photosynthetic bacteria from activated sledge and biomembrane.The results showed that:the flocculation capacity of activated sludge of treated wastewater was better under the aerobic and darkness condition than that under the aerobic and illumination condition;the photosynthetic bacteria were forced to act as aerobic respiration under the aerobic and darkness condition,so organics biodegradation rate of monosodium glutamate wastewater was improved,moreover effluence COD of treated wastewater and removal rate of organics were better under the aerobic and darkness condition than that under the aerobic and illumination condition.
