Garlic straw-nanocopper composite blue alga treatment agent and preparation method thereof

Abstract

The invention discloses a garlic straw-nanocopper composite blue alga treatment agent. The blue alga treatment agent is prepared from, by weight, 40-60 parts of diatomite, 5-10 parts of plant ash, 5-10 parts of garlic straws, 3-5 parts of nanocopper, 0.2-0.4 parts of acrylamide, 3-5 parts of sodium gluconate, 0.3-0.5 parts of polyethyleneimine, 0.03-0.05 parts of ammonium persulfate, 1-2 parts of alum, 0.5-1 part of hydroxyethylurea, 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, lasting effectiveness, 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 garlic stalk-nanometer copper composite cyanobacteria treatment agent 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. T...

AI Technical Summary

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
