以生活污水为底物,利用改造后的BIOLOG微平板,对活性污泥激活剂进行定性和定量试验;利用初筛的活性污泥激活剂,采用活性污泥法对生活污水进行降解试验.实验结果表明,VC、VE、L-His、γ-氨基丁酸、L-Ala对活性污泥有一定的激活作用.当底物为200μL时,L-His的最佳用量为1μL;γ-氨基丁酸的最佳用量为0.5μL;L-Ala的最佳用量为0.5μL;VE的最佳用量为1μL;VC的最佳用量为1μL.其中VE对提高生活污水COD的降解效果明显.
In this experiment , domestic sewage was used as substrate .Using the modified BIOLOG microplate , a series of qualitative and quantitative test of the activated sludge activators was done .Using activated sludge acti-vators, the domestic wastewater was degraded by the method of active sludge .The experimental results showed that VC,VE, L-His,γ-aminobutyric acid , L-Ala had certain activation effect on activated sludge .When the substrate was 200 μL, the optimum dosage of L-His is 1μL;the best dosage of γ-aminobutyric acid is 0.5μL;the optimum dosage of L-Ala is 0.5 μL;the optimum dosage of VE is 1 μL;the optimum dosage of VC is 1 μL.The degrada-tion effect of VE on COD was significantly increased .
