Abstract

The invention provides a high-efficiency high-temperature activated carbon adsorbent. Raw materials of the adsorbent comprise activated carbon and lipase liquid, wherein the mass ratio of the activated carbon to the lipase liquid is 1:(10-20); and the lipase liquid is lipase liquid secreted during mixed fermentation culture of pseudomonas putida, pseudomonas fluorescens and denitrifying bacteria.According to the adsorbent disclosed by the invention, the adopted lipase liquid is the lipase liquid secreted by mixed fermentation of the pseudomonas putida, pseudomonas fluorescens and denitrifyingbacteria on a culture medium added with industrial wastewater. The lipase liquid can adapt to an environment of the industrial wastewater in the culture medium, is applicable to high-temperature conditions, can still maintain extremely high activity under the high-temperature conditions, and has stability. The lipase liquid has excellent adsorption effects on heavy metal ions and organic matters.The activated carbon adsorbent prepared by performing synergistic matching on the lipase liquid with the characteristics and the activated carbon has excellent high temperature resistance.

Description

Technical field[0001]The present invention relates to the field of sewage treatment, and more particularly to a highly efficient high-temperature activated carbon suction agent.Background technique[0002]With the development of the economy, there are more and more chemical plants in all parts of the chemical plant, and the treatment of industrial sewage has become a hot spot in all sectors. At present, industrial wastewater treatment is common technologies with activated carbon adsorption, zeolite exchange. However, activated carbon has a small amount of adsorption of heavy metal ions and organic matter in wastewater, and a large amount of activated carbon is used for each treatment of wastewater, and the cost is higher. The use of bacterial secretion of lipase fluid treatment of activated carbon although the amount of activated carbon can be improved, these lipases currently utilized are very sensitive to temperature, and their activity will be restricted by temperature. At elevated...
