Abstract

Abstract: Load magnetic flocculation method has the advantages of high sedimentation efficiency, low hydraulic retention time and good treatment effect, but it has little treatment effect for high concentration of heavy metal wastewater.In this paper, the influences of the temperature, pH, the content of pollutants, hydraulic conditions, the kinds of flocculation and dosing quantity impact on flocculation effect were introduced.The application of load magnetic flocculation in the treatment of paper mill wastewater, wastewater containing copper and arsenic and waste filter and so on was expounded.It was found that load magnetic flocculation is not only suitable for heavy metal wastewater treatment, but also has best effects in oil, suspended solids, and sewage treatment. And with the mature and perfect of the technology, load magnetic flocculation method will be more broad prospects for development.

Key words: load magnetic flocculation method, magnetic separation technology, wastewater, flocculation, degradation, nucleation

摘要： 磁加载絮凝法具有高沉降性、占地面积小、处理优良等特点,但存在对处理高浓度重金属废水的出水效果不好及尚未达到工业化等问题。本文介绍了温度、pH、污染物的含量、水力条件、絮凝剂的种类及投加量对絮凝作用的影响,阐述了磁加载絮凝法在处理造纸厂污水、含砷废水、含铜废水、垃圾滤渗液等各种重金属废水的应用研究,并通过对其应用研究的分析表明了磁加载絮凝技术不仅适用于重金属废水处理,在油类、悬浮物及生活污水的处理中也取得了很好的结果,并且随着该技术不断成熟和完善,磁加载絮凝法会有更为广阔的发展前景。
