用味精废水活性污泥处理厌氧废水实验研究

A TEST STUDY OF TREATMENT OF WASTEWATER FROM FERMENTATION BY ACTIVE SLUDGE OF MONOSODIUM GLUTAMATE WASTEWATER

试验结果表明 :在双氧水作用下 ,利用驯化的味精废水活性污泥处理厌氧废水 ,对CODCr,BOD5和色度具有较高的去除效果 ,处理过程受到温度、活性污泥加入量和双氧水加入量的影响 ,活性污泥用量是最主要的影响因素 ,双氧水的加入量与TOC (总碳 )的去除率成正比 ,而色度与TOC的去除率有密切关系。在 30℃、活性污泥用量等于废水量、理论双氧水加入量、不另加氮源、曝气 72h等实验条件下 ,活性污泥法处理厌氧废水 ,CODCr去除率达 79 1 % ,BOD5去除率达 71 0 % ,脱色率高达 93 8% 。

Under affecting of H 2O 2,an active sludge of monosodium glutamate waste water has been used to treat waste water from fermentation .Experimental results show that treatment processor is found to be the best method in terms of color and affected by temperature,added active sludge and hydrogen peroxide amount.79 1% COD Cr ,71 0% BOD 5, 93 8% color have been removed under the operating conditions as 30 ℃,active sludge waste water amount and stoichiometric hydrogen peroxide without nitrogen source a...
