specific Embodiment approach 1
[0007] Embodiment 1: A method of serially removing algae by using zooplankton and filter-feeding fish in this embodiment is accomplished as follows: at least two water storage facilities are connected in series, and then the algae-containing water flows through each water storage in sequence facilities, the hydraulic retention time in each water storage facility is 1 to 3 days, and zooplankton or filter-feeding fish are alternately stocked in two adjacent water storage facilities. The fish in the water storage facilities stocking zooplankton are completely cleaned out or carnivorous fish are put in to eliminate the filter feeding of Daphnia daphnia by filter-feeding fish. The fish in the water storage facilities stocking filter-feeding fish are silver carp and Bighead carp or silver carp only; silver carp and bighead carp or only silver carp are stocked at a density of 40-200g / m 3 , the weight of a single silver carp is 60-500g, the stocking density ratio of bighead carp to si...
specific Embodiment approach 2
[0008] Specific implementation mode 2: The zooplankton in the water storage facility for stocking zooplankton in this embodiment adopts the stocking method of artificial dosing or natural growth, and one can be selected according to actual needs. Other method steps are the same as those in the first embodiment.
specific Embodiment approach 3
[0009] Embodiment 3: The water storage facilities in this embodiment are reservoirs, reservoirs or lakes, and these waters can be treated to remove algae. Other method steps are the same as those in the first embodiment.
