Blue alga treatment agent adopting licorice root residues as raw material, and preparation method thereof

Abstract

The invention discloses a blue alga treatment agent adopting licorice root residues as a raw material. The blue alga treatment agent is prepared from, by weight, 5-10 parts of the licorice root residues, 3-5 parts of pine needle powder, 0.2-0.4 parts of sodium dodecyl sulfonate, 30-40 parts of diatomite, 20-30 parts of meerschaum, 3-5 parts of glutinous rice flour, 0.2-0.4 parts of acrylamide, 0.03-0.05 parts of ammonium persulfate, 0.5-1 part of an EVA emulsion and 10-15 parts of a composite assistant. The blue alga treatment agent has the advantages of good adsorption activity and flocculation performance, very good flocculation effect on blue algae, fast blue alga removal rate, low cost, no secondary pollution, high cyanotoxin adsorption and removal efficiency, good removal effect on various organic and inorganic pollution substances in water, bacterium killing and alga inhibiting efficacy, effective improvement of the quality of water, and suitableness for treatment of complex water environment.

Description

technical field [0001] The invention relates to the field of cyanobacteria treatment, in particular to a cyanobacteria treatment agent with licorice residue as raw material and a preparation method thereof. Background technique [0002] my country is a country with many lakes and reservoirs. In recent years, with the aggravation and expansion of eutrophication in water bodies, freshwater cyanobacteria blooms have flooded, which not only seriously hinders the normal life of residents, but also affects the water ecosystem. Development has a greater negative impact. At the same time, cyanotoxins, secondary metabolites produced in cyanobacterial blooms, are toxic to organisms and pose serious health risks to humans. Therefore, the control of cyanobacterial blooms has become a research hotspot that has received extensive attention. [0003] At present, the control of cyanobacterial blooms in lakes can be roughly divided into three methods: physical, chemical and biological. The...

Problems solved by technology

The physical method is mainly based on mechanical algae removal, which has the problems of large engineering volume, long operation cycle, and high one-time investment cost; although the effect of chemical algae removal is good, it is easy to cause secondary pollution to the environment; biological algae removal technology is not mature, Practical application faces certain difficulties

Moreover, existing conventional water treatment processes cannot effectively remove algae toxins present in water
