摘　　要：研究了不同磁场强度对不同成分有机污水COD浓度的影响,试验表明不同成分有机污水COD浓度磁处理后都有所降低,自来水、有机污水磁处理后,溶解氧浓度降低,去离子水磁处理后溶解氧浓度没有变化.机理分析结果,认为磁处理一方面增强了空气的氧化性能;另一方面,由于吸收了磁场中的能量,物质从稳定态向不稳定的激发态靠近;再一方面,磁场促进了有机物的自由基反应,从而表现出磁处理后有机污水COD浓度降低.This paper deals with the effect of different magnetic intensities on the chemical oxygen demand(COD) of different organic sewage components. The results show that the COD of different organic sewage components could be decreased. With the magnetic treatment impact, the dissolved oxygen of the tap water and the municipal sewage also could be decreased and the dissolved oxygen of the deionized water could not be changed. The experimental results are analyzed as viewed from three points: the first is that, with the magnetic field impact, the air oxidation ability could be accelerated; the second is that the organic substance would trend to instability due to the absorption of magnetic energy; and the third is that the radical pair reaction could be accelerated in the magnetic field.
