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．
This paper introduces the structure and viscosity properties of a novel flocculant modified with silicic acid, a plant-based polymer, and uses a water supply source as the research object. The coagulation treatment is performed under the synergistic action of a magnetic field, and the turbidity, amount of residual aluminum, Oxygen consumption and other indicators reflect the possibility of effective depth treatment based on conventional water treatment processes. The results show that the aluminum content in the effluent after flocculation can be reduced below 0.05mg/L under this working condition, and the oxygen consumption is also reduced. The effect of the magnetic field is related to the nature of the water body. When the pH is around 6 to 6.7, the magnetic field is conducive to flocculation and aluminum reduction. The mechanism analysis suggests that the magnetic field promotes the adsorption process and the bridging effect of the polymer flocculant, so that the purification effect of the micro-particles in the water body is improved.
