摘要
采用强电场电离氧、水分子,在分子层次上按羟基物质结构加工成羟基溶液,再把它加入压载水主输送管道内,实现在压载水输送管道中杀灭浮游动植物、细菌.在0.6mg/L低浓度下,仅2.67s致死浮游动植物、细菌效率达100%.羟基具有氧化、分解浮游植物光合色素能力,在8s内使叶绿素a、b、c及类胡萝卜素含量均减少了35%～64%,停滞5min后,叶绿素a、b、c及类胡萝卜素含量均减少到低于检测方法的最低限值,是浮游植物致死原因之一.剩余羟基分解成H2O、O2等无害物质,不存在任何残留药剂.实现了在输送管道中治理压载水,成为船上治理压载水惟一有效可行的绿色新方法,解决了由于船舶压载水造成海洋外来入侵性传播的问题.
Using strong electric field, the molecules of oxygen and water are ionized. According to the substantial structure of hydroxyl radical, they are made into hydroxyl solution on the molecule scale, then hydroxyl solution is injected into the main pipe of transporting ballast water, which realizes the process of killing phytoplankton, zooplankton and bacterium during transporting ballast water in the pipe. When the concentration of hydroxyl solution is 0.6 mg/L, it is only in 2.67 seconds that the rate of killing phytoplankton, zooplankton and bacterium attains to 100%. Owing to the characteristic of hydroxyl radical decomposing the photosynthetic pigment of phytoplankton, the contents of chl-a, chl-b, chl-c and carotenoid are all decreased 35%～64% in 8 seconds, while the contents of chl-a, chl-b, chl-c and carotenoid are all decreased to below the lowest limit of test method after 5 minutes, which is one of the reasons of killing the phytoplankton. The residual hydroxyl radicals are decomposed into some innocuous substances such as H_2O and O_2 without any residua. This method realizes the process of treating ballast water in ship's transporting pipe and becomes an only effective green new method to treat ballast water on ship and control the invasive spread of exotic specials in the ballast water.
