通过自行设计的强磁水处理循环系统,进行了葡萄糖和淀粉溶液这两种模拟有机污水的磁处理试验研究.结果表明:磁处理使两种溶液的COD值出现不同程度的下降,其中300mg/L葡萄糖溶液在磁场强度1150mT,流速2m/s,水温30℃,处理2h条件下,COD最大降幅达到10.1%;300mg/L淀粉溶液在磁场强度1200mT,流速2m/s,水温30℃,处理时间2.5h条件下,COD最大降幅为17.6%.由此可见,对于不同溶液,影响磁处理效果的最佳条件不同.文章最后对其作用机理进行了推断.

High-strength magnetic fields generated by a lab-scale device of static magnets were applied to the experi-ment for treating aqueous solutions containing glucose and starch respectively. The study found that magnetic treatment reduced COD of the both aqueous solutions for the glucose, a max degradation of 10.1% of COD when magnetic intensity was 1150mT; for starch, a max degradation of 17.6% of COD when the magnetic intensity was 1200 roT. It was also found that the solution, flow velocity and retention time in the magnetic field affected the treatment. Mechanism involved with the COD decline of organic matters treated in magnetic fields was discussed as well.
