Influence of Iron Salt on the Treatment of Monosodium-Glutamate Wastewater by Biochemistry Process
The manufacture of monosodium glutamate generates significant quantities of wastewater.Industrial monosodium-glutamate wastewater is usually characterized by low temperature,strong acidity,high chemical oxygen demand(COD) and biological oxygen demand(BOD)values,high concentration SO42-and high quantity of bacteria.The treatment of sulfate-laden industrial monosodium-glutamate wastewater by biochemistry process is Iimited by the high concentration of sulfate.Anaerobic reaction and two-stage anaerobic fluidized bed reactors are used to improve this process by suitable and highly efficient methods to remove sulfate.Based on experiments,the the effect of iron salt on the treatment efficiency of industrial monosodium-glutamate wastewater by biochemistry process was studied.Fe2+ facilitates the reduction of sulfate jon and inereases the removal ratio of sulfate ion.It is feasible to adopt biological iron method in treating monosodium-glutamate wastewater with two-stage anaerobic fluidized bed reactor.This process can increase the removal ratio of COD and SO42-manifestly.The SO42-loading and the COD loading remain in a high levelin the biochemical process,and the efnciency of wastewater treatment is improved considerably.
