| Abstract: | Iron-carbon reduction method was used to treat high concentrated monosodium L-glutamate wastewater. Results showed that cast-iron was better than stainless steel to raise pH value of monosodium L-glutamate wastewater, and pH value could be increased from 1.97 to 4.88 when cast-iron was used. COD removal rate increased with pH rising in iron-carbon reduction process and the removal reached 52.5% at pH 9.0. The increment of Fe~(2+) concentration was 3395mg/L when pH was raised from 1.96 to 4.88. |
