Problems solved by technology

However, the use of chemical reagents is likely to cause secondary pollution to the water body, and it is not easy to carry out follow-up treatment; in addition, among the biological improvement measures currently used, the bacteria with the most obvious application effects mainly include photosynthetic bacteria, bacillus, lactic acid bacteria, and actinomycetes etc., because they belong to different species, photosynthetic bacteria are photoautotrophic, while other species are chemoheterotrophic, bacillus are spore-forming bacteria, while other species are non-spore-forming bacteria, the growth conditions and nutritional requirements vary greatly, At present, most of the microbial preparations for improving water bodies are mixed multi-effect strains. The compound strain preparations with different functions and growth conditions are not only easy to interact with each other in the growth period, but also unable to play a role in the later process of water body treatment. To a good effect of improving the environment

Abstract

The invention discloses a compound bacteria culture composition, which includes proteus morganii culture, proteus mirabilis culture, filamentous Streptomyces culture, bacillus thuringiensis culture and candida mycoderma bacteria culture. The compound bacteria culture composition is prepared by mixed-culturing proteus morganii culture, proteus mirabilis culture, filamentous Streptomyces culture, bacillus thuringiensis culture and candida mycoderma bacteria culture according to part by weight; under the condition of tolerating toxicity of heavy metals, the composition releases antibiotic and canplay safe and effective purifying effect to sewage commonly polluted by pathogenic bacteria and heavy metals.

Description

technical field [0001] The present invention relates to a microbial composition, its preparation method and application, in particular to a compound bacteria culture composition used for the treatment of sewage polluted by pathogenic bacteria and heavy metals, and its preparation method and application. Background technique [0002] The pathogenic microorganisms in the water body mainly come from human and animal feces and domestic sewage pollution, which can be divided into three categories: bacteria, viruses and protozoa; there are various ways for pollutants to enter the water source. Particulate matter settles into natural water sources under the action of gravity, and the solid and liquid wastes in domestic wastewater enter the water body directly with sewage pipes; in addition to pollutants such as pathogenic microorganisms that easily cause public safety hazards, industrial water separation wastewater It carries a large amount of heavy metal pollution sources into the...
