Deoiling powdery blue-green algae treatment agent and preparation method thereof

Abstract

The invention relates to a deoiling powdery blue-green algae treatment agent which is prepared from the following raw materials in parts by weight: 14-18 parts of tetra calcium aluminoferrite, 5-7 parts of hydroxyethyl cellulose, 10-15 parts of filter powder, 10-14 parts of expanded graphite, 20-24 parts of vermiculite, 14-19 parts of calcium carbonate, 3-5 parts of ligneous calcium sulphonate, 6-9 parts of titanium dioxide, 8-12 parts of iron oxide red powder, a proper amount of water, 13-16 parts of tea dregs, 13-16 parts of astragalus smicus and 3-4 parts of an adsorption auxiliary. By using astragalus smicus, the deoiling powdery blue-green algae treatment agent after high-temperature treatment is not only good in suspension property and good in adsorption on blue-green algae, but also is high in nitrogen content of astragalus smicus; the n/p ratio of water quality can be improved, the growth of blue-green algae is inhibited, and by match of expanded graphite and vermiculite, the deoiling powdery blue-green algae treatment agent can adsorb blue-green algae, is good in suspension property and easy to gather and fish. Moreover, the expanded graphite is good in oil absorption. By adding titanium dioxide and iron oxide red powder, ecological balance is not affected while the blue-green algae are killed by catalytic oxidation.

Description

technical field [0001] The invention relates to a treatment agent for sewage treatment and environmental treatment, in particular to an oil-removing powdery cyanobacteria treatment agent and a preparation method thereof. Background technique [0002] Cyanobacteria are algae, also known as blue-green algae. Of all algal organisms, cyanobacteria are the simplest and most primitive. The phenomenon that the ecological balance is destroyed due to the extremely bad water resource environment leading to the proliferation of cyanobacteria is called "cyanobacteria bloom". Cyanobacteria blooms can cause the death of fish and shrimp, lead to water pollution, and have a serious impact on human production and life. In addition, cyanotoxins can seriously endanger human health. In the United States, Japan, Australia, Brazil and other countries, there have been reports of fish, livestock and human poisoning deaths caused by algae toxins. The frequency of cyanobacterial blooms in many la...

Problems solved by technology

Other biological methods, such as filter-feeding fish control and algae competition, are not very effective or safe enough for large green bloom outbreaks

[0007] Application of commercial flocculants (such as polyaluminum chloride and polyferric chloride) to remove algae in natural water bodies has safety problems, such as aluminum in polyaluminum chloride can cause damage to the brain and nervous system, and the amount of flocculants is large , high cost, which also limits its use

[0008] Although there are many methods for controlling cyanobacteria, each method has its own advantages and disadvantages and cannot be widely used.
