Sodium bentonite processing agent for blue-green algae and preparation method thereof

Abstract

A sodium bentonite processing agent for blue-green algae is prepared from the following raw materials in parts by weight: 10-20 parts of serpentine, 40-45 parts of sodium-base bentonite, 2-3 parts of magnesium chloride, 8-13 parts of calcium chloride, 15-20 parts of potassium ferrate(VI), 12-16 parts of equisetum hyemale, 13-16 parts of pericarpium granati, 3-5 parts of polymaleic acid, 3-4 parts of sodium pyrophosphate, 2-3 parts of urea, 3-5 parts of anhydrous sodium sulfate, 3-5 parts of boric acid, 4-6 parts of polyvinyl alcohol, proper amount of water, and 3-4 parts of an adsorption auxiliary agent. By adding potassium ferrate(VI), the processing agent for blue-green algae has synergic effects of oxidation, adsorption, flocculating, precipitation, sterilization, disinfection, decoloring and deodoring, also does not generate any toxic and harmful substances, is capable of increasing water dissolved-oxygen content, has good removal effects on ammonia nitrogen, nitrites and algae in water, and is used to remove fulvic acid and suspensions in water and eutrophication phenomenon in fresh water. The processing agent for blue-green algae is good in dispersing suspending property and good in adsorption property, and can help to rapidly aggregate and salvage blue-green algae.

Description

technical field [0001] The invention relates to a treatment agent for sewage treatment and environmental treatment, in particular to a sodium-based bentonite 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 l...

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.
