城市污水磁化处理的试验研究

Experimental Study on Municipal Sewage Magnetization Treatment

用电磁装置对城市污水进行磁化试验的研究,发现磁化能引起BOD_5、COD_(Cr)、藻类生产力和细菌总数等一系列污染指标呈周期性异常变化。对变化机理进行初步探讨,认为是由于磁场力的直接作用使有机污染物矿化引起的。试验结果表明,磁化引起污水耗氧特性的改善和促进藻类生产力提高的后期效应,可应用于研究开发污水处理的新技术和强化传统污水处理工艺。

A series of sewage were treated with a set of magnetic equipments, and caused abnormal changes of BOD5, CODcr, primary production of algae and total number of bacteria. The author gave a preliminary explanation that the magnetic field force directly caused the mineralization of some organic pollutants. The results showed that magnetization caused ameliorating oxygen demand characteristic and promoting posterior effect of algae production. This method could be developed as a new sewage treatment technology and strengthening the traditional sewage treatment process.
