摘要
测试了自制的高取代度阳离子淀粉作为絮凝剂时的性能,试验表明高取代度的阳离子淀粉对于高浊度水有较好的絮凝效果,其絮凝效果与阳离子聚丙烯酰胺(CPAM)的絮凝效果接近,且在弱酸性条件下絮凝效果较好,而在碱性条件下絮凝效果较差。与阳离子聚丙烯酰胺相比,高取代度阳离子淀粉具有成本低、无毒性、高效、易降解等优点。
This cationic starch with high degree substitution can be used as a flocculent. The flocculating result was excellent when we put the starch into the high turbidity water. The flocculating effect and removing turbidity were as good as that of cationic polyacrylamide (CPAM). What is more, the flocculating effect was affected by pH measurement. The flocculating effect was better in acid solution as well as worse in alkaline solution.
