Description

technical field [0001] The invention relates to the field of embedding and immobilizing microorganisms and the field of preparation equipment for embedding and immobilizing microorganisms, in particular to a preparation method and a preparation device for embedding and immobilizing microorganism balls. Background technique [0002] In the past few decades, my country's industry has developed rapidly and the living standards of the people have been continuously improved. However, with the development of industry, the pollution of industry to the environment has become more and more serious. In recent years, people's awareness of environmental protection has gradually strengthened, and the government has paid more and more attention to environmental governance. [0003] Among the many sources of pollution, the problem of water pollution is particularly prominent. Among them, the pollution of oceans and rivers caused by blowouts, leaks from transport ships, sinking ships, and l...
