摘要
运用磁场对生活废水进行磁化处理并观察其生物效应.对磁化杀菌作用、好氧生物活性变化和藻类生长促进作用等进行了试验测定.结果表明,磁化处理对污水中的细菌具有较强的杀菌作用;当磁场强度达到3500Gs时,好氧生物活性增加18%;与未磁化污水比较,磁化水藻类初级生产力可以提高1倍.本文还进一步分析探讨了其生物效应机制.
The biologic effects of the magnetic treatment of sewage were studied by applying magnetic filed to sanitary wastewater. Tests on the bactericidal action, activity of aerobe and the promotion action of algae growth wore carried out. The result showed that magnetic treatment had the effective power to kill bacteria in sewage. The acrobc activity increased by 18% when the magnetic field was at 3500 GS: the primary productivity of algae was two times as big as the mi-magnetized sewage. Moreover, the bactericidal mechanism, acceleration function to aerobe activity and algae productivity of magnetic treatment have been analyzed.
