摘要:
对高强磁化处理技术在景观水治理中杀藻的应用效果进行了研究。实验结果表明:在磁场强度为3700Gs的高强磁水处理器的作用下,水体中藻类数量由50万个/mL降到5万个/mL,蓝藻基本消除;COD、氨氮、总磷的含量分别由处理前的56.1mg/L、3.37mg/L、1.53mg/L降到28.0mg/L、0.26mg/L、0.96mg/L;水体溶氧量和透明度则分别由原来的2.40mg/L、40cm提高到7.20mg/L、75cm(见到池底),水体质量明显改善。

abstract:
Based on experimental analysis of magnetization in landscape water treatment, this paper studied the magnetic treatment effects on the growth of algae and the removal of nutrient material. The results indicated that at the magnetic field intensity of 3700Gs the density of algae can decreased from 50×104cells/mL to 5×104cells/mL, COD, NH3-N, TP from 56.1mg/L, 3.37mg/L,1.53mg/L to 28.0mg/L,. 0.26mg/L, 0.96mg/L and DO, transparency increased from 2.40 mg/L, 40cm to 7.20mg/L, 75cm.
