| 中文摘要 |
| 介绍以纤维素为主的植物高分子硅酸改性新型絮凝剂的结构、粘度等性能,以给水水源为研究对象,在磁场的协同作用下强化混凝处理,通过浊度、残铝量、耗氧量等指标反应了在常规给水处理工艺的基础上进行有效深度处理的可能性。结果表明,本工作条件下可以将絮凝后出水的铝含量降至0.05mg/L以下,耗氧量也有降低。磁场作用与水体的性质有关,pH值为6-6.7左右时磁场有利于絮凝降铝。机理分析认为磁场促进了吸附过程和高分子絮凝剂的搭桥作用,使得水体中的微颗粒净化效果得以改善。 |
| 英文摘要 |
| A new type of natural plant polymer mainly made of cellulose which was modified with silicon was studied.The properties such as the structure and viscosity were tested and the effects on the coagulation in cooperation with magnetic field were experimentally researched.The targets of turbidity,aluminum remains and oxygen consumption reflected the possibilities of the deeply effective treatment on the basis of the routine feed water treatment technique.The results showed that the aluminum content could be reduced below 0.05mg/L after the flocculation and the oxygen consumption was also decreased.Furthermore,the magnetic effects bear relationship with the nature of the water system.When the pH value of water is 6—6.7,the magnetic field is benefit to the sedimantation of aluminum.The magnetic field was considered to promote the adsorption and the bridge formation of the polymer flocculant so that the tiny particles in the water were removed more completely. |
