Problems solved by technology

Monovalent cation Na + 、K + etc. have a certain coagulation-promoting effect, but the effect is not obvious; while divalent cations, such as Ca 2+ It is generally believed that it mainly plays the role of chemical bridging, which can significantly improve the flocculation effect of organic flocculants, Mg 2+ , Fe 2+ It can also improve the flocculation effect of organic flocculants; trivalent cations are mainly Al3+, etc., which have a better coagulation-promoting effect, but because the residues in water are rich in toxicity and easy to accumulate in the environment, so it is rarely used

Abstract

The invention discloses a key material of a modified straw flocculant and a technical method for same. The key material includes, by weight part ratio: ozonized ultrapure water, straw powder, phenyl succinic acid, nonyl phenol sulfosuccinic monoester disodium salt, N-(2-methphenyl)trichloroacetamide, 1-amino-2-bromo-4-[(4-methphenyl)amino]-9,10-anthracenedione, 1-amino-4-bromoanthraquinone, 3,5-dimethoxybromobenzene, berkelium nano particles, 1-amino-2-bromo-4-hydroxyanthraquinone, 2-[(4-chloro-2-nitrophenyl)azo]-N-(2,3-dihydro-2-oxy-1H-benzoimidazole-5-yl)-3-oxo-butanamide, and 2-[[4-cyclohexylamino-9,10-dihydro-9,10-dioxy-1-anthryl]amino]-5-ethoxybenzenesulfonic sodium salt. The key material herein achieves synchronization of an organic flocculant during production and avoids complex steps of producing and purifying a bio-flocculant and compounding the bio-flocculant with the organic flocculant to complete the production of the compound flocculant, thereby reducing synthesize process and reducing cost.

Description

technical field [0001] The invention belongs to the field of flocculants for environmental treatment, and in particular relates to a key material of a modified straw flocculant and a technical method thereof. Background technique [0002] Flocculant is a polymer substance with flocculation activity produced by organic matter. It is biodegradable and environmentally safe. Its main components are protein, polysaccharide, cellulose, lipid and nucleic acid. It is non-toxic, safe to use, and A new type of flocculant with biodegradation and other characteristics. [0003] The flocculation performance of flocculants is greatly affected by cations, and different valence cations have different effects on the flocculation performance of biological flocculants. Metal ions can strengthen the bridging and neutralizing effects of bioflocculants. Monovalent cation Na + 、K + etc. have a certain coagulation-promoting effect, but the effect is not obvious; while divalent cations, such as ...
