摘要：

We designed and prepared the container-type movable "treatment equipment for preventing and controlling non-indigenous marine organism invasion risk in case of emergency" with a volume of 30 t/h based on advanced oxidation processes of strong electric-field discharge at atmospheric pressure and the hydrodynamic cavitation technology, and the equipment was used to perform the application experiments of sea water in the fourth wharf of Dalian Port. Moreover, we investigated the performance of ballast water treatment system from bio-availability, related chemical analysis and water quality change. The results show that when the processing capacity is 35 t/h, the contents of phytoplankton and bacteria are 1.6×103 mL-1 and 610 CFU•mL-1, respectively, and the treatment effect can meet the discharge standard of D-2 of International Maritime Organization (IMO). The total organic carbon (TOC), the turbidity and chlorophyll significantly decrease in treated water; however, the concentration of Tribromomethane (TBM) slightly increases in treated water and is lower than World Health Organization drinking water standard. Finally, the water quality is improved significantly. Therefore, the emergency treatment device is safe and reliable to deal with the risk of foreign marine biological invasion, and the treatment effect meet the requirements of discharge standard of IMO. © 2019, High Voltage Engineering Editorial Department of CEPRI.
