Organic microsphere with blue-green alga removing function and preparation method thereof

Abstract

The invention discloses a preparation method of an organic microsphere with a blue-green alga removing function. The preparation method comprises the following steps: (1) dissolving sodium alginate and polyglutamic acid in water; (2) putting 0.15 g of graphene oxide into 50 ml of deionized water, adding the formed solution into a mixed solution of sodium alginate and polyglutamic acid obtained inthe step (1), and adding diatomite and bentonite; (3) dropwise adding a mixture obtained in the step (2) into a calcium chloride stationary liquid, carrying out a reaction for 30-120 minutes, and carrying out washing with deionized water 2-3 times for later use after the reaction is finished; (4) treating a solid substance prepared in the step (3) for 10-30 minutes under the condition that a microwave power is 600-1200W so as to obtain an organic microsphere; and (5) putting the organic microsphere into a blue-green algae removal microbial inoculum, and conducting standing for 5-10 hours to obtain the organic microsphere with the blue-green alga removing function. The organic microsphere is capable of reducing the sunlight irradiation amount of a water body and inhibiting excessive propagation of blue algae, moss and the like in the water body.

Description

technical field [0001] The invention belongs to the technical field of water body purification, and in particular relates to an organic microsphere with the function of removing cyanobacteria and a preparation method thereof. Background technique [0002] Cyanobacteria are cyanobacteria, also known as blue-green algae. It is one of the most primitive and ancient algal plants. Its main features are: simple plant body, unicellular, various groups and filaments; there is no eukaryote in the cell, but the center of the cell contains nuclear material, which is usually granular or reticular, without nuclear membrane and nucleolus, and has a nuclear function, so it is called prokaryotic. Because of this, most modern scholars advocate separating cyanobacteria from the plant kingdom, together with prokaryotic bacteria, and standing alone as the prokaryotic kingdom. Cyanobacteria do not have organelles such as chloroplasts, mitochondria, Golgi bodies, endoplasmic reticulum, and vac...

Problems solved by technology

[0004] In the prior art, when degrading cyanobacteria, cyanobacteria-removing bacteria agents are often sown into the water body, but the cyanobacteria-removing bacteria agents sink to the bottom of the water soon after spreading from the water surface, thereby affecting its function
