Abstract

The invention relates to the field of biological carrier technology, in particular to an activated carbon polyvinyl alcohol ball. Components of the activated carbon polyvinyl alcohol ball include 5-16% of polyvinyl alcohol, 1-25% of activated carbon, 0.5-5% of sodium alginate, and 65-85% of water. The activated carbon polyvinyl alcohol ball is small in diameter, contains the activated carbon on the surface and inside, and enables the specific surface areas of carriers with the same filling ratio to be greatly increased. Meanwhile, many -OH radicals exist in the activated carbon polyvinyl alcohol ball, so the activated carbon polyvinyl alcohol ball has the advantages of being good in hydrophilicity and superior in endophilicity with microorganisms, and the like. In addition, the invention further discloses an activated carbon polyvinyl alcohol ball preparation method which has the advantages of being simple in process, strong in operability, and the like.

Description

technical field

[0001] The invention relates to the technical field of biological carriers, specifically an activated carbon polyvinyl alcohol ball, and meanwhile, the invention also discloses a preparation method of the activated carbon polyvinyl alcohol ball. Background technique

[0002] Biofilm sewage treatment technology is the development direction of the current sewage treatment technology. Through certain technical means, the selected microorganisms are enriched on the carrier, so that the microorganisms can be fixed and grow, which is conducive to improving the quality and quantity of microorganisms in the bioreactor and improving the system. Capability and adaptability, shorten processing time, reduce processing cost, keep it active and reusable. Biofilm technology was mainly used in the field of fermentation production at first, and was used in the field of water treatment in the late 1970s. Compared with traditional sewage biological treatment technology, biofilm...
