Abstract

The invention discloses a cordierite-polylactic acid fiber composite blue-green alga treating agent. The blue-green alga treating agent is prepared from, by weight, 10-15 parts of cordierite, 30-40 parts of sodium bentonite, 1-2 parts of boric acid, 1-2 parts of nanometer zirconia, 3-5 parts of polylactic acid fiber, 0.2-0.4 part of acrylamide, 0.03-0.05 part of ammonium persulfate, 3-5 parts of sisal residue, 0.5-1 part of sodium potassium tartrate tetrahydrate and 10-15 parts of compound additive. The blue-green alga treating agent has high adsorption activity and flocculating performance, blue-green alga flocculating effect is good, blue-green alga removal speed is high, cost is low, secondary pollution is avoided, blue-green alga toxin adsorption removal efficiency is high, the effect of removing various organic and inorganic pollutants in water is good, water quality is effectively improved, and the blue-green alga treating agent is suitable for treatment of a complicated water environment.

Description

technical field

[0001] The invention relates to the field of cyanobacteria treatment, in particular to a cordierite-polylactic acid fiber 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....
