The growth inhibition of M.aeruginosa was investigated in the packedbed plasma reactor from the aspects of the content of malonaldehyde (MDA), electrolysis on the membrane permeability, and changes in dissolved organic carbon (DOC) to analyze the mechanism of the inactivation of M.aeruginosa. The results show that the content of MDA of the test sample is higher than that of the control sample, but the difference between the test and control sample decreases. The electrolysis on the membrane permeability is 7130% and 8061%, respectively after 40 min and 60 min treatment, which are higher than those of the control sample (56% and 50%). In the storage period, the electrolysis on the membrane permeability increases rapidly, and then decreases, but it is still higher than that of the control sample. The content of DOC of the test sample is higher than that of the control sample immediately after 40 min and 60 min treatment. Then, the content of the test sample decreases while that of the control sample obviously increases from 604 mg/L to 1067 mg/L.

Low frequency microwaves propagate through coplanar waveguide in the quasistatic TEM mode, and the cross section electric field and magnetic field interact to produce electromagnetic body force along the coplanar waveguide.
