| | 基础排水论文 摘要:壳聚糖可以有效去除三氯甲烷、二氯乙烷等具有变异性或致癌性的基础排水论文消毒副产物,并且对饮用水中的基础排水论文细菌有一定的灭菌作用。最新研究发现,将壳聚糖作为聚合氯化铝的助凝剂,处理北京昆明湖的湖水,结果表明,其助凝作用明显,浊度及有机物的去除率明显提高。壳聚糖在吸附去除饮用水中有害物质的同时,不吸附水中的K+、Ca2+、Na+、Mg2+、SO42-、Cl-、HCO3-等离子,不影响天然水体的本底浓度,且有抑菌、杀菌作用,是饮用水净化的理想吸附剂。考虑到壳聚糖的生产成本及我国给水水质的实际情况,将无机高分子絮凝剂和壳聚糖天然絮凝剂复配,是我国水处理剂发展的趋势。 关键词:壳聚糖 蛋白废水 絮凝剂
Abstract:The shell can get rid of chloroform , two chlorine ethane ,etc. effectively and have variability or carcinogenic disinfecting accessory substances while gathering candies, and have certain sterilization function on the bacterium in the drinking water . Discover , gather shell candy is it get chlorine to help and congealing the pharmaceutical aluminium together to regard as newly, dealing with the lake water of Kunming Lake in Beijing, the result indicates , it helps function of congealing to be obvious, turbid degree and getting rid of rate of the organic matter obviously improve. Shell gather candy in absorb while getting rid of drinking water harmful substancing , K+、Ca2+、Na+、Mg2+、SO42-、Cl-、HCO-3 ,etc. of adsorbed water, do not influence this density of bottom of the natural water body , and restrain funguses , sterilization function , it is the ideal absorbent which drinks aqueous cleaning. Consider shell gather production cost and our country of candy supply water actual conditions of water quality, gather inorganic high polymer flocculant and shell candy natural flocculant is it mix to reply , of our country water treatment pharmaceutical development trend Keyword:The shell gathers candies Albumen waste water Flocculant 壳聚糖是甲壳素的脱乙酰基产物。甲壳素广泛地存在于甲壳类动物的外壳以及许多低等植物如菌、藻类的细胞壁中。自然界每年可生物合成甲壳素数十亿吨,它是储量仅次于纤维素的又一丰富的自然资源。80年代以来,对甲壳素、壳聚糖的性质和应用的研究日趋活跃,它们在生物、医学、化工、食品等许多领域中都显示了广阔的应用前景。壳聚糖在水处理方面的应用又表现出其独特的优势,由于壳聚糖分子中含有大量的游离氨基,在适当条件下,能够表现出阳离子型聚电解质的性质,是一种很有发展前途的天然高分子絮凝剂。我们将壳聚糖絮凝剂用于蛋白质的回收试验,取得了很好的效果。另外,还测了壳聚糖乙酸溶液的黏度。
