The invention discloses a
bacteria-
algae composition for degrading water and directionally eliminating blue-
green algae, the
bacteria-
algae composition comprises the following components in percentage by weight: 80%-85% of compound
bacteria, 5%-10% of compound
enzyme and 10%-15% of
nutrient elements, and the compound bacteria comprise 25%-30% of
bacillus licheniformis, 20%-25% of
bacillus subtilis, 5%-10% of compound
enzyme and 10%-15% of
nutrient elements, 17%-28% of
lactobacillus plantarum, 13%-20% of
rhodopseudomonas palustris and 13%-20% of
rhodotorula glutinis; the compound
enzyme comprises the following components in percentage by
mass: 30% of
pectinase, 30% of
glucanase and 40% of
cellulase. Stable proliferation can be realized under a relatively
low dissolved oxygen condition, and the
energy consumption required by
aeration is reduced. The selected strains are consistent in growth rate and have compound
fermentation conditions, so that the production and use cost is reduced. By adding
chlorella into the complex
microbial inoculant, the proliferation stability and the
nitrogen,
phosphorus and COD removal capacity of the complex
microbial inoculant are improved, the directional degradation effect on
cyanobacteria is achieved, and
cyanobacterial bloom is inhibited.
