摘要
采用羟基处理压载水技术,使用羟基处理设备和管道作为模拟船舶排放压载水的管道。研究了羟基对海产小球藻、游仆虫和异养细菌的杀灭效果,说明羟基能有效杀灭压载水中的微小生物;并模拟船舶排放压载水过程中排放地的海水对处理后压载水的稀释作用,稀释后的水样经过96h的培养,没有发现微小生物复活的情况,证明了羟基杀灭船舶压载水微小生物在长度为4m(接触时间为2s)的接触管道内已经完成。并研究了羟基处理压载水技术对水质情况的影响,结果表明羟基有效杀灭船舶压载水微小生物的同时能改善压载水水质。
The authors used the ship ballast water treatment equipment of hydroxyl radicle and its piping as the letting piping of ballast water on the ship. Experiment results of Euplotes,Chloreua Pyrenoidesa,and Heterotrophic Bacteria prove that hydroxyl radicle can effectively kill tiny organisms in ship ballast water. And they simulated the hydroxyl radicle diluedness by seawater in the area under ship in the course of ballast water letting. The results show that no living organism is found after 96hr culture in dilued ballast water, and prove that the killing process has been completed in the blending piping of 4 m length or in blending time of 2 s. The water quality experiment results show that hydroxyl radicle can improve the status of ship ballast water as well as kill invasive organisms.
