摘要
The present invention relates to the field of water environment treatment, and particularly discloses a method for treating phytoplankton by non-traditional biomanipulation. The method comprises: introducing filter-feeding fishes into an area where the to-be-treated phytoplankton is located, carrying out premagnetisation on a water body entering the area, and then arranging an electromagnetic type magnetisation reactor in a direction perpendicular to water flow in the area to carry out intermittent magnetisation on the water body, wherein the magnetic field intensity is 50mT to 2000mT, an intermittent period is 3h to 240h, and the one-time magnetisation time is 5min to 300min. According to the method, the activity of algae cells can be inhibited and the activities of amylase and plant cellulase in digestive systems of the filter-feeding fishes can be improved so as to improve the digestibility of algae and promote metabolism of the fishes; and meanwhile, reproduction of bacteria can also be inhibited, and decomposition of fish faeces by the bacteria is reduced, so that the secondary outbreak of the algae is avoided.
