[0022] Example 1:
[0023] A blue-green algae scavenger with pumice as a carrier, which is prepared from cerium nitrate solution, sodium hydroxide solution and bulk pumice raw materials. The addition amount of sodium hydroxide solution is 1% of the volume of the cerium nitrate solution. The amount added is 5% of the total mass of the cerium nitrate solution and the sodium hydroxide solution; wherein the mass concentration of the cerium nitrate solution is 0.2%, and the mass concentration of the sodium hydroxide solution is 5%; the massive pumice is: the pumice is broken Into a block with a diameter of 0.5 cm, wash with a sodium hydroxide solution with a mass concentration of 8% for 1.5 hours, wash it to neutrality, and dry to obtain block pumice.
[0024] The above-mentioned preparation method of cyanobacteria scavenger using pumice as a carrier includes the following steps:
[0025] 1) Crush the pumice stone into blocks with a diameter of 0.5 cm, stir and wash for 1.5 hours with ...

[0029] Example 2:
[0030]A blue-green algae scavenger with pumice as a carrier. It is prepared from cerium nitrate solution, sodium hydroxide solution and bulk pumice raw materials. The amount of sodium hydroxide solution added is 5% of the volume of the cerium nitrate solution. The amount added is 10% of the total mass of the cerium nitrate solution and the sodium hydroxide solution; the mass concentration of the cerium nitrate solution is 0.5%, and the mass concentration of the sodium hydroxide solution is 10%; the massive pumice is: the pumice is broken Into a block with a diameter of 3 cm, stir and wash with a sodium hydroxide solution with a mass concentration of 12% for 2.5 hours, then wash to neutrality, and dry to obtain block pumice.
[0031] The above-mentioned preparation method of cyanobacteria scavenger using pumice as a carrier includes the following steps:
[0032] 1) Crush the pumice stone into blocks with a diameter of 3 cm, stir and wash for 2.5 hours with a sod...

[0036] Example 3:
[0037] A blue-green algae scavenger with pumice as a carrier. It is prepared from cerium nitrate solution, sodium hydroxide solution and bulk pumice raw materials. The amount of sodium hydroxide solution added is 3% of the volume of the cerium nitrate solution. The added amount is 8% of the total mass of the cerium nitrate solution and the sodium hydroxide solution; wherein the mass concentration of the cerium nitrate solution is 0.4%, and the mass concentration of the sodium hydroxide solution is 8%; the massive pumice is: the pumice is broken Into a block with a diameter of 1 cm, stir and wash with a sodium hydroxide solution with a mass concentration of 10% for 2.0 hours, then wash to neutrality, and dry to obtain block pumice.
[0038] The above-mentioned preparation method of cyanobacteria scavenger using pumice as a carrier includes the following steps:
[0039] 1) Crush the pumice stone into blocks with a diameter of 1 cm, stir and wash with a sodium hyd...
