Abstract:
Objective To assess the efficiency of algae extermination by the combined copper electrolysis technology. Methods The combined copper electrolysis technology and copper sulphate were used to treat the Synechocystissp strain PCC6803 in the steady stage of culture in different time and the efficiency of algae extermination was assessed. Results No alga in the water sample was detected after 0.5 and 1 hour of treatment with copper electrolysis technology and copper sulphate respectivly as the concentration of Cu2+ was at 0.3 mg/L. The extermination rate of algae was 80.75% after 12 days of treatment of combined copper electrolysis. This technology could effectively decrease the turbidity, smell, COD, ammonia nitrogen and increase the dissolved oxygen in the treated water. Conclusion The Cu2+ released by copper electrolyzing has a stronger efficiency of algae extermination compared with copper sulfate. The combined copper electrolysis technology will be a satisfactory method for algae extermination in the landscape water.
