Modified zeolite-nanocarbon cyanobacteria treatment agent and preparing method thereof

Abstract

The invention discloses a modified zeolite-nanocarbon cyanobacteria treatment agent. The modified zeolite-nanocarbon cyanobacteria treatment agent is prepared from, by weight, 30-40 parts of zeolite, 10-20 parts of kieselguhr, 3-5 parts of nanocarbon, 0.1-0.2 part of maleic anhydride, 1-2 parts of ethyl orthosilicate, 3-5 parts of kapok fibers, 0.2-0.4 part of acrylamide, 0.3-0.5 part of hydroxyethyl cellulose, 0.03-0.05 part of ammonium persulfate and 10-15 parts of a composite assistant. The cyanobacteria treatment agent has good adsorption activity and flocculating performance, has very good flocculation on cyanobacteria, is high in cyanobacteria removing speed, low in cost and free of secondary pollution, also has a good adsorption and removing effect on cyanobacteria toxins and various organic and inorganic pollutants in water, especially has the decomposition and conversion effects on organic pollutants and toxins, and is capable of effectively improving the water quality and suitable for treatment in complex water environments.

Description

technical field [0001] The invention relates to the field of cyanobacteria treatment, in particular to a modified zeolite-nano carbon 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. The physical...

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
