Carbon-based cyanobacteria inhibiting and purifying material as well as preparation method and application thereof

The invention discloses a carbon-based cyanobacteria inhibiting and purifying material as well as a preparation method and application thereof. The material is prepared from the following raw materials in parts by mass: 40-50 parts of a carbon-based material, 15-25 parts of an inhibiting and purifying material, 5-10 parts of potassium humate, 5-10 parts of nitro humic acid and 5-10 parts of a complex microbial inoculant. The carbon-based cyanobacteria inhibiting and purifying material can effectively improve the growth and metabolism environment of benthic algae in water, supplement a carbon source, improve the C/N/P ratio of the water and adjust the C/N/P balance, and is beneficial to growth and propagation of benthic organisms, water purification, efficient removal of organic pollutantsin the water and reduction of heavy metal pollution. Therefore, the growth and propagation of the cyanobacteria are effectively inhibited by inhibiting cell division, and the inhibiting and purifyingmaterial is low in prepara
