英文摘要	Conference Name:7th International Conference on Applied Electrostatics, ICAES 2012. Conference Address: Dalian, China. Time:September 17, 2012 - September 19, 2012.; Ministry of Education of China; National Natural Science Foundation of China; Dalian University of Technology; Nanjing Suman Electronics Co. Ltd; Shekonic Electric/Mechanical Co. Ltd; Suzhou TA and A Ultra Clean Technology Co. Ltd.; Global Environment Facility has identified that the spread of marine invasive alien species is one of the four major risk factors threatening the safety of global marine environments. Ballast water discharge is the main cause of biological invasion. With physical methods of strong electric field ionization discharge at atmospheric pressure, O2 and sea water (gaseous) were ionized, and then dissociated to a number of oxygen active particles (ROS) such as ·OH, O2+, H 2O+, etc. ROS was injected into 0.6 t h-1 ballast water treatment system to form high concentration ROS solution in order to kill the harmful micro-organisms in ballast water. According to the land-based test standard of International Maritime Organization (IMO) Guidelines for Approval of Ballast Water Management Systems (G8), this paper concludes that single-cell algae of 3.0 × 104 cell ml-1 and bacteria of 2.0 × 104 cfu ml-1 were killed by ROS solution of 2.0 ppm. Death rate could reach almost 100%. The results meet the requirements of Regulation D-2 of International Convention for the Control and Management of Ships' Ballast Water and Sediments completely. ?
