Abstract

The invention relates to a microorganism immobilization carrier material, a bio-adsorbent prepared from the microorganism immobilization carrier material, and a preparation method and application of the bio-adsorbent. The microorganism immobilization carrier material is a material which is composed of carbonized straw powder, sodium alginate and a chitosan / CNT material and used for immobilizing aerobic microorganisms. The bio-adsorbent is obtained by immobilizing microorganisms on the carrier material through adsorption-embedding-chemical bonding of the microorganism immobilization carrier material. According to the invention, a three-dimensional structure is formed between inorganic and organic carriers, oriented macropores are generated, a pore diameter is uniform, attachment growth of microorganisms is facilitated, and relatively high microbial activity and relatively good mass transfer property can be maintained; and the bio-adsorbent is high in a selective phenol adsorption rate, small in influence on the environment of a water body, optimal in adsorption performance in a pH value range of 5-8, high in an adsorption speed, and capable of basically achieving balance within 60 minutes.

Description

technical field

[0001] The invention relates to a carrier material for water treatment, in particular to a microorganism immobilized carrier material, a biosorbent prepared by using it, a preparation method and an application. Background technique

[0002] Common industrial wastewater, such as coal chemical industry, dyestuff, pharmaceutical, pesticide, and papermaking, contains high concentrations of organic substances, and is a common highly toxic and refractory organic wastewater. If discharged randomly, it will not only harm the growth and reproduction of animals and plants, but also endanger human life and health. For the treatment of industrial wastewater, there are usually adsorption methods, flocculation sedimentation methods, biodegradation methods, etc., and good results have been achieved in past research. However, with the continuous development of society, treatment methods and treatment agents also need to be updated.

[0003] Biodegradation is an economical,...
