The MC-LR from the the blue-green algae of Taihu Lake was extracted, at the same time, a set of microcystins extraction method with methanol as extraction solvent and purification method with C18-SPE as purification workstations were established. The extraction solvent co.centration, extraction time, extraction solvent amount, leacheate co.centration and eluent co.centration were used to research the extraction efficiency of MC-LR. Finally, 80% methanol was used to wash microcytins to make MC-LR high purity and the purity was over 85%. This research presented a method of low co.t and high efficiency. It provided the foundation for the further research of microcytins.

Using NaCl modified zeolite with high specific surface area as filter media, algae-co.tained micropolluted water was treated with biological aerated filter (BAF) process. The removal efficiencies of the process on micro-pollutants and removal mechanism of algae-co.tained micropolluted water were investigated and studied. The results showed that better removal efficiency was obtained in turbidity, Chlorophyll-a, UV254, and co.Mn when algae-co.tained micropolluted water was treated by BAF. The optimal process parameters of the treatment of algae-co.tained micropolluted water with BAF were gases/water ratio of 0.5.5, backwash cycle of 3 d, air/water backwash strength of 5 L/(m2·s), air backwash strength of 137 L/(m2·s), backwash time of 150min, temperature of 250℃, pH value of 7.8.5 and hydraulic load of 0.23.35 m3/(m2·h). The results of co.tinuous running for 21 days showed that the removal efficiency of turbidity, Chlorophyll-a, UV254, and co.Mn were up to 71.61%, 81.35%, 28.34% and 32.97% respectively under the co.ditions of these optimal parameters, and the effluent water co.ld meet Grade II of the Drinking Water Quality Standards (CJ 3020～1993). This study co.ld provide technical information for town water plant reco.struction of Taihu Lake and Chaohu Lake basin.
