Embodiment 1

[0032] Weigh each component according to the following weight (unit: kg): copper sulfate 8, zinc carbonate 2, aluminum sulfate 50, bentonite 25, calcium carbonate 10 and modified starch (purchased from Shanghai Kanghu Chemical Co., Ltd., its trade name It is "oxidized starch") 5; after dissolving copper sulfate and zinc carbonate with 5 liters of water, mix them with aluminum sulfate, bentonite, calcium carbonate and modified starch, and mix the uniform powder according to the routine, and use conventional methods (such as extruding or disc) granulation to obtain granules, the specifications of which are as follows: diameter is 2-5mm, specific gravity<2.0, can stay in water for 3-5 minutes and keep its geometric prototype, 24-hour discreteness is greater than 80-90%.

Embodiment 2

[0034] Each component was weighed according to the following weight (unit: kg): copper sulfate 15, zinc carbonate 5, aluminum hydroxysulfate 60, montmorillonite 30, calcium carbonate 15 and modified starch (purchased from Shanghai Kanghu Chemical Co., Ltd., Its trade name is "oxidized starch") 10; Dissolve copper sulfate and zinc carbonate in 10 liters of water, mix the solution with aluminum hydroxysulfate, then mix evenly with montmorillonite, calcium carbonate and modified starch, and mix according to the conventional method Uniform powder, granulated by conventional methods (such as extrusion or discs) to obtain granules, the specifications are as follows: diameter 2-5mm, specific gravity <2.0, can stay in water for 3-5 minutes and maintain its geometric prototype, 24 Hourly dispersion is greater than 80-90%.

Embodiment 3

[0036] Weigh each component (unit: kg) according to the following weight: copper sulfate 2, zinc carbonate 5, aluminum chloride 40, diatomaceous earth 20, calcium carbonate 5 and modified starch (purchased from Shanghai Kanghu Chemical Co., Ltd., Its trade name is " oxidized starch ") 0.5; After dissolving copper sulfate and zinc carbonate with 6 liters of water, mix them with aluminum chloride, diatomaceous earth, calcium carbonate and modified starch, and mix them uniformly according to the conventional method. Powder, granulated by conventional methods (such as extrusion or disc) to obtain granules, the specifications are as follows: diameter 2-5mm, specific gravity <2.0, can stay in water for 3-5 minutes and maintain its geometric prototype, 24 hours discrete Sex greater than 80-90%.

Abstract

The invention discloses a water body algaecide and a method for the production thereof. The water body algaecide comprises the following components by weight: copper agent in an amount of 2 to 15 parts, zinc agent of 0 to 10 parts, aluminum agent of 40 to 60 parts, carriers of 20 to 30 parts, calcium carbonate of 5 to 15 parts and coating agent of 0.5 to 10 parts. The water body algaecide of the invention has a plurality of persistent efficacies of alga removing, flocculation, sedimentation and phosphorus consolidation, and can remove the algae effectively and prevent water bloom.

Description

technical field [0001] The present invention relates to a water purifying agent, in particular to a water purifying agent composed of copper, zinc, aluminum, iron, calcium and other metal ions loaded on clay, which has the functions of algae removal, flocculation, precipitation and phosphorus fixation. The algae agent, the invention also relates to the preparation method of the water body algicide and its application in water treatment, belonging to the field of water treatment engineering. Background technique [0002] As we all know, the reason for the deterioration of urban landscape water bodies is the eutrophication of water bodies, or the phenomenon of algal blooms. If people can eliminate and alleviate water blooms and inhibit the growth of algae, they can realize the purpose of clear water, happy fish, fresh air and tourists' willingness to stop. [0003] The eutrophication process of the water body is the result of the continuous reproduction of the algae of the au...
