Blue alga treatment agent capable of purifying water and preparation method thereof

Abstract

The invention relates to a blue alga treatment agent capable of purifying water. The blue alga treatment agent is prepared from the following raw materials in parts by weight: 20-25 parts of activated bauxite, 10-20 parts of Chinese medicine residues, 3-5 parts of anhydrous sodium sulfate, 10-20 parts of mordenite, 20-25 parts of starch microspheres, 5-7 parts of polyaspartic acid, 0.1-0.2 part of potassium permanganate, 0.4-0.6 part of NaOH, 10-14 parts of aluminum potassium sulfate, 2-4 parts of hydroxypropyl methyl cellulose, 5-7 parts of benzalkonium bromide, 10-20 parts of mushroom residues, 4-6 parts of ZnO, a suitable amount of water and 4-6 parts of adsorbing auxiliary agents. The blue alga treatment agent disclosed by the invention has the advantages of good adsorption and good flocculation effect, is capable of fast removing the blue algae, the bacteria and the organic pollutants, has good floatability through alkali treatment by using the Chinese medicine residues and the mushroom residues, achieves the antibacterial effect and good adsorption effect and is environmental-friendly and energy-saving without secondary pollution to the environment.

Description

technical field [0001] The invention relates to a treatment agent for sewage treatment and environmental treatment, in particular to a water-purifying 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 in...

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.
