Blue algae treating agent containing alfalfa roots and preparation method thereof

Abstract

The invention discloses a blue algae treating agent containing alfalfa roots. The blue algae treating agent is prepared from the following raw materials in parts by weight: 40-60 parts of clays, 20-30 parts of brick slag, 20-30 parts of alfalfa roots, 14-18 parts of aluminum potassium sulfate, 5-7 parts of calcined gypsum, 9-13 parts of calcium chloride, 6-9 parts of ferric oxide, 8-10 parts of rice chaff, 13-17 parts of sophora alopecuroide, 2-3 parts of carrageenan, 12-15 parts of ammonium alum, proper amount of water and 3-4 parts of adsorption auxiliaries. According to the blue algae treating agent, the alfalfa roots are used, so that nitrogen content of water quality is increased, N / P ratio is increased, and the growth of the blue algae can be inhibited; by adding rice chaff and sophora alopecuroide, the growth of the blue algae can also be inhibited, and the growth of green algae is promoted; meanwhile, the clays and the brick slag which are subjected to high-temperature treatment and grinded are cooperatively used and are high in suspension property, so that the adsorbability to the blue algae is high and the blue algae is easy to fish out. Not by using a chemical or physical method, the treating agent can inhibit the growth of the blue algae for a long time, cannot destroy the biological balance, is suitable for preventing and controlling the blue algae and can also remove heavy metal ions and organic pollutants in the water at the same time.

Description

technical field [0001] The invention relates to a treatment agent for sewage treatment and environmental treatment, in particular to a cyanobacteria treatment agent containing alfalfa root 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 ...

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.
