摘　　要：在强电离放电电场作用下,H2O、O2分子进行电离、分解电离和电荷交换反应,在分子层次上加工成高浓度羟基溶液,加入压载水输送管道内,仅距加入点4m长度地方取样检测,压载水的羟基比值浓度达到0.63mg/L时,原生动物、浮游植物、细菌浓度分别从4.4×104/mL、6.0×104/mL、1.9×105/mL均减少到低于检测方法的最低限;剩余羟基药剂分解成H2O、O2等,无残留物.羟基溶液是治理压载水有效、廉价、无残留物的理想方法.Under strong electric field, molecules of H_2O and O_2 undergo a series of changes of ionization, deassociation and charge exchanging, and finally most of them turn into hydroxyl radicals. In this experiment, high concentration solution of hydroxyl is injected into the main pipe for transporting ballast water and then samples for testing are taken 4 m away along the main pipe. As the ratio concentration of hydroxyl amounts to 0.63 mg/L, the content of protozoan, phytoplankton and germs,with initial concentration of 4.4×10~4/mL, 6.0×10~4/mL and 1.9×10~5/mL respectively, decreases so greatly that it's lower than that can be detected. Surplus hydroxyl degenerates into H_2O and O_2. It is verified that the solution of hydroxyl is a new and ideal method, with the characteristic of effect, low cost and residue free, to treat ballast.
