[0025] The preparation steps of treatment agent are as follows:
[0026] Step 1: Preparation of organic-inorganic flocculant
[0027] (1.1) Dissolve ferric chloride in distilled water at 0.5 g / ml and add sodium carbonate powder to stir. After the foam disappears, add sodium hydrogen phosphate according to the molar ratio of phosphorus: iron = 0.08, and continue to stir until dissolved to obtain polychloride Iron, wherein the mass ratio of ferric chloride to sodium carbonate is 17: (1-3);
[0028] (1.2) Control the reaction temperature in an ice bath at 10-20°C, add epichlorohydrin dropwise to dimethylamine, add ethylenediamine after 2 hours, raise the temperature to 60-75°C and react for 5-7 hours to obtain polycyclic Propylene oxide-dimethylamine, wherein the molar ratio of dimethylamine to epichlorohydrin is 1:1, and the molar ratio of ethylenediamine to dimethylamine is 0.1:1;
[0029] (1.3) Add the polypropylene oxide-dimethylamine prepared in the step (1.2) to the polyf...

The invention discloses a water blue-green alga treating agent as well as a preparation method and application thereof. The treating agent comprises an organic-inorganic flocculant, polyaluminum chloride, sodium metasilicate, a microbial agent and N-methyl pyrrolidone, wherein the organic-inorganic flocculant combines organic flocculation and inorganic flocculation, so that the organic-inorganic flocculant has adsorption neutralization and adsorption bridging functions at the same time, and the flocculation effect of a single flocculant is greatly improved; various flocculants are compounded,different flocculation mechanisms are combined, blue-green algae are flocculated rapidly and effectively, a large amount of flocculated blue-green algae float on the water surface, then the gathered blue-green algae are decomposed under the action of a microbial agent, and decomposition is carried out on the water surface, so the blue-green algae are prevented from releasing toxin in the water body, and the health of the water body is ensured; an anti-settling agent is also added into the treating agent, the stability of the treating agent is effectively improved, the uniform and stable performance of the treating agent is ensured, and the treating agent provided by the invention is simple and convenient in preparation process and suitable for wide popularization and application.
Description
technical field [0001] The invention relates to the technical field of environmental treatment, in particular to a water body cyanobacteria treatment agent and its preparation method and application. Background technique [0002] Cyanobacteria, also known as blue-green algae cyanobacteria, most of the cyanobacteria have a gelatinous coat outside the cell wall, so they are also called sticky algae. Among algal organisms, cyanobacteria are the simplest and most primitive single-celled organisms. They have no nucleus, and there is a nuclear substance in the center of the cell, which is usually granular or reticular. The pigment is evenly distributed in the cytoplasm, and the nuclear substance has no nuclear membrane and nucleolus. , has the function of nucleus, so it is called prokaryotic or pseudonucleoid. There are circular DNA plasmids in cyanobacteria, which act as carriers. In the water body, because it is mostly stagnant water, it is easy to cause the accumulation of org...
