摘要:A method was developed for cyanobacteria bloom (unicellular and colonial Microc;ystis aeruginosa) mitigation using calcium hydroxide and an illite composite algicide. The maximum cell removal efficiency was 84.72% when calcium hydroxide was used alone. When illite and calcium hydroxide were used together, the removal efficiency increased to 90.43% within 9 h. In addition, the results also showed that the composite algicide could remove total nitrogen (TN) and total phosphorus (TP) in eu-trophic water. However, the removal efficiency of TP is more evident than that of TN under the same composite algicide doses. Thus, the method would provide an alternative composite algicide to mitigate cyanobacteria blooms using calcium hydroxide and illite in eutrophic water.
