Problems solved by technology

[0005] At present, there are hundreds of commercially produced bacterial agents, but due to the particularity of the water quality of black and odorous water bodies, ordinary microbial agents are not suitable for black and odorous water bodies, and the treatment effect is not good, especially cannot be removed or inhibited in a targeted manner Harmful algae in water bodies make water ecology difficult to restore

Abstract

The invention discloses a composite micro-ecological preparation for treating black and odorous water body, which belongs to the technical field of biology and water treatment. The composite micro-ecological preparation for treating black and odorous water is prepared from the following components: 50-70mL of composite microorganisms with the concentration of 107-1010cfu / mL, 10-15g of enzyme, 3-8gof a biosurfactant, 5-10g of microorganism source algistat and the balance of water, totaling 100mL, according to the composite micro-ecological preparation for treating the black and odorous water body, the black and odorous water body is treated through the synergistic effect of all the components, the water quality is rapidly and effectively improved, the water ecology is restored, and the self-cleaning capacity of the water body is restored.

Description

technical field [0001] The invention belongs to the technical field of biology and water treatment, and in particular relates to a compound microecological preparation for treating black and odorous water bodies. Background technique [0002] Black and odorous water body is a general term for water bodies that exhibit unpleasant colors (black and blackish) and / or emit unpleasant odors (stinky or foul smell). With the acceleration of industrialization and urbanization in my country, improper protection of water bodies, wide sources of nutrients in water bodies, and abnormally high background concentrations have resulted in many water bodies being in a state of eutrophication, and the water body environment is very fragile. [0003] Urban black and odorous water treatment is a systematic project, the main treatment idea is: source control-burden reduction-purification-restoration, mainly including physical methods, chemical methods and biological methods. Commonly used physic...
