Abstract

The invention discloses antibacterial and algae-killing active carbon and a preparation method thereof, which comprises the following steps: applying acrylonitrile-styrol reisn to the surface of active carbon; performing chemical treatment so as to combine the acrylonitrile-styrol reisn with copper ions. The acrylonitrile-styrol reisn is firmly combined on active carbon, thus being safe and nontoxic to the environment. The antibacterial and algae-killing active carbon has an antibacterial effect on tested golden staphylococcus, colon bacillus, white candida, micrococcus lutea, bacillus subtilis, etc., and has a good effect of killing various types of algae such as microcystic aeruginosa DS, microcystic aeruginosa 7820, Plectonemaboryanum IU594, chlammydomonas reinhardtii, scenedesmus obliquus, etc., which cause algae bloom in fresh water. The antibacterial and algae-killing active carbon can be used for sterilization and treatment of algae bloom in fresh water in environmental cleaning.

Description

technical field The invention relates to an antibacterial and algaecidal activated carbon, and also relates to a preparation method of the antibacterial and algaecidal activated carbon. The application scope of the antibacterial and algaecidal activated carbon is the field of sterilization in environmental purification and freshwater bloom control. Background technique "Water blooms" are a natural ecological phenomenon in fresh water. The vast majority of water blooms are caused only by algae, such as cyanobacteria (strictly called cyanobacteria), green algae, diatoms, etc. When " wawter bloom " took place, water generally was blue or green. This " wawter bloom " phenomenon that just has in nature, just on the books in ancient my country history. After eutrophication in fresh water, "water blooms" appear frequently, the area spreads year by year, and the duration is extended year by year. According to a recent survey, 53%, 28%, 48% and 41% of the lakes in Europe, Africa,...
