Composite biochar immobilized microbial filler and its application in the degradation of volatile organic pollutants

Abstract

The present invention discloses a composite biochar immobilized microbial filler and its application in the degradation of volatile organic pollutants. The composite biochar immobilized microbial filler utilizes bamboo fiber, thermoplastic polyurethane, and bamboo biochar as the carrier, and is made with efficient degradation bacterial suspension for volatile organic pollutants as the active microorganism. The composite biochar immobilized microbial filler prepared by the present invention has advantages such as high surface activity, high mechanical strength, high degradation efficiency, and high microbial immobilization capacity. It enhances the adsorption and degradation ability of microorganisms towards VOCs while simultaneously improving the mechanical strength of the immobilized microbial filler, thereby addressing challenges in biological purification technology. The biochar immobilized microbial filler of this invention is used for the degradation of volatile organic pollutants, wherein the polyurethane and bamboo material are inexpensive and easily obtainable, and the preparation process is simple and efficient, offering significant economic cost advantages.
