羟基对海水水质影响的研究

低浓度羟基溶液能100％致死浮游动植物、细菌、弧菌、孢子，同时又大幅度改善了压载水水质。在每小时处理2t压载水的模拟试验中取得如下改善水质数据：对生物有害的亚硝酸盐、氨盐的下降率高达98．35％、99．5％；浊度下降50％，水的透明度有明显的改善；C0T从0．54mg／L减少到未检出；由于羟基对细胞残骸的氧化分解，使TOC含量上升了1倍；Cu、Pb、Fe下降幅度分别达到38．1％、70．8％、40．3％，对生物无害的Zn增加近2倍，这是因Zn是许多酶和蛋白质分子的活性中心原子，羟基分解细胞后，溢出溶入水中所致。保证了排放地域水生生物的安全。

Effect of Hydroxyl Radical on Quality of Seawater

Low concentration hydroxyl is enough to kill the Zooplankton,phytoplankton,germ,vibrion,spore with 100% efficiency,meanwhile to improve significantly the quality of ballast water.The experimental data for 2 t/h system of ship's ballast water indicated that the removal efficiency of nitrite and ammonium salt reached to 98.35%and 99.5% ,the turbidity was decreased to 50% resulting in the better transparency,and COT was reduced from 0.54 mg/L to no test.Because of the oxygenolysis of hydroxyl to cell body,TOC increased 1 time,the contents of Cu,Pb,Fe decreased 38.1% ,70.8%,40.3% respectively.Zn which is no any harm to organism raised 2 times because Zn,as an activated center element of many enzymes and protein,was extracted out and dissolved into water after the cells were decomposed by hydroxyl.In this way,the aquatic species in maritime space and port are in safety.
