摘要
以重庆唐家桥污水处理厂活性污泥为研究对象,对其中的活性微生物菌群进行了富集培养、分离纯化、絮凝活性测试,并采用显色反应和傅里叶变换红外光谱法对其产生的微生物絮凝剂进行了结构表征。结果表明,絮凝活性最强的优势菌种为酵母菌菌落,其絮凝率超过95%;该酵母菌菌落进行发酵培养、分离、提纯得到黄色晶体状的微生物絮凝剂,通过呈色反应和红外光谱分析,推测出该微生物絮凝剂为一种糖类物质及可能存在的官能团结构。
Active bacteria from activated sludge in Tangjiaqiao sewage treatment plant were enriched, cultivated, separated and purified, and their degree of activity tested. Structural characteristics of the microbial flocculant produced by the activated bacteria were analyzed using coloration reaction and Fourier transform infrared spectrometry. The results show that the most active bacterium is saccharomycetes with a flocculation ratio reaching as high as 95%. Yellow crystal microbial flocculent was obtained through fermentation cultivation, separation and purification from these saccharomycetes. Results of the coloration reaction and infrared absorption spectrometry indicate this microbial flocculent is a type of sugar in which there are numerous functional groups.
