摘要: Ships’ ballast water can carry aquatic organisms into foreign ecosystems. In our previous studies, a concept using ion exchange membrane electrolysis to treat has been proven. addition other substantial approaches, new strategy for inactivating algae is proposed based on the developed treatment system. strategy, means of multi-trial injection with small doses electrolytic products applied algae. To demonstrate performance contrast experiments between strategies and routine processes were conducted. Four species including Chlorella vulgaris, Platymonas subcordiformis, Prorocentrum micans Karenia mikimotoi chosen as samples. The different experimental parameters are studied times products. Compared conventional one trial method, mortality rate time (MRT) available chlorine concentration be saved up about 84% 40%, respectively, under application strategy. approach great potential in practical treatment. Furthermore, also helpful deep insight mechanism algal tolerance.
