Kaolin composite processing agent for blue-green algae and preparation method thereof

Abstract

A kaolin composite processing agent for blue-green algae is prepared from the following raw materials in parts by weight: 15-20 parts of dolomite, 4-6 parts of polyethyleneimine, 6-8 parts of zinc sulfate, 5 parts of fructus bruceae, 7-10 parts of alfalfa root, 50-60 parts of kaolin, 3-5 parts of sodium hexametaphosphate, 2-3 parts of oxalic acid, 0.4-0.7 part of sodium dithionite, 5-7 parts of silicon oxide, 3-5 parts of sodium silicate, 9-12 parts of hollow glass microsphere, 2-4 parts of calcium dihydrogenphoshate, proper amount of water and 4-5 parts of a dispersing auxiliary agent. The blue-green algae processing agent is capable of rapidly killing blue-green algae and other harmful algae in water, is strong in polymerization capability and good in dispersibility and suspension property, enables blue-green algae to be easily salvaged and processed, and has the characteristics of being nontoxic, harmless to waterweeds, free of residues and the like after being used. By using alfalfa root, the nitrogen-phosphorus ratio of water is improved, growth of green algae is facilitated, and growth of blue-green algae is inhibited.

Description

technical field [0001] The invention relates to a treatment agent for sewage treatment and environmental treatment, in particular to a kaolin composite 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 lakes i...

AI Technical Summary

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.
