SBR法降解味精废水中有机质的试验研究

Study on degradation of organic substrate of MG wastewater with sequencing batch reactor

用 SBR法处理味精废水中有机质的实验结果表明 ,ML SS在 50 0 0～ 6 0 0 0 m g/L、有机负荷在 0 .3～ 0 .4 kg CO DCr·( kg MLSS· d) -1时有机质降解效果最好。二段 SBR法克服了葡萄糖效应 ,提高了有机质的降解效果。其中 SBR( )反应器中有机质降解呈零级反应动力学关系 ,在 SBR( )

The optimum process operating conditions for SBR were found to be: MLSS 5 000~6 000 mg/L, \{F/M\}0.3-0.4 kgCOD\-\{Cr\}/(kgMLSS\5d). The degradation of organic substrate in the first stage of a two\|stage SBR was followed by zero order kinetics, while it followed first order kinetics in the second stage. Because two\|stage SBR overcame 'glucose effect', the biodegradation performame of organic substrate was increased.\;
