| Abstract: | The oxidative biocide,which is called sodium dichloroisocyanurate, was used to control the growth of the microbe in the circulating cooling water.The adding concentration of the biocide,the temperature, interaction time and pH were investigated respectively for the bactericidal ratio.The parameter for operation by evaluating each factor and its three level variations' effect on the bactericidal result could be obtained.The experiments show the biocide concentration has the biggest influence on bactericidal result,the second is interact time,the third is temperature and the last is pH. |

| Keywords: | microbe biocide cooling water influence factor bactericidal performance activated carbon and biochemical oxygen demand |
