改性淀粉絮凝剂的研究

改性淀粉絮凝剂具有无毒、原料来源广、价格低、易于生物降解等优点,近年来得到重视和发展应用。综述了接枝类改性淀粉絮凝剂、离子化改性淀粉絮凝剂如淀粉醚类化合物以及淀粉黄原酸脂类等天然改性淀粉絮凝剂的研究进展及在水处理中的应用。提出改性淀粉絮凝剂未来的发展前景和研究方向。利用我国极为丰富的淀粉资源,开发出更多高效、无毒、价廉的改性淀粉絮凝剂,以满足各种废水处理的不同需要;开发以淀粉为原料的改性天然高分子絮凝剂具有重要的现实意义。

Study of Modified Starch Flocculant

Modified starch flocculants had a series of virtues such as non-toxicity,abundance in resources,low price and biodegradability.In recent year people had paid highly attention to develop and apply it in treating wastewater.The research progress in graft copolymers starch,ionized modified starch such as etherified starch and xanthate modified starch,and theirs application in water treatment were introduced.The advanced prospect and research aspect of modified starch flocculent were predicted.By making full use of resources abundant in starch in our state,a great deal of highly effective,non-toxic and cheap modified starch will be studied to adapt to all kinds of wastewater.It showed that developing modified organic flocculants made by natural starch was very significant.
