This paper shows property conversion of water and removing characteristics of Escherichia coli for discharge tube with $ZrO_2$ beads. At the result of the removal characteristic experiments of Escherichia coli using the discharge tube with $ZrO_2$ beads, because the electric field is also increased when input voltage is increased, the removal characteristic of Escherichia coli was appeared relation connection to input voltage. And if a passing number of test water in discharge tube with $ZrO_2$beads is increased, the removal ratio of Escherichia coli is to be increased because passing number of electric field section is increased. And if diameter of $ZrO_2$beads is increased, the removal time of Escherichia coli is to be decreased because dielectric polalization of $ZrO_2$beads. Also, the removal ratio of Escherichia coli of the discharge tube with $ZrO_2$beads. is appeared higher than the removal ratio of the discharge tube without $ZrO_2$beads. And a satulation punt of ozone and $H_2$ $O_2$generation density inner water was appeared near 60[min].
