Abstract
The invention belongs to the technical field of biological denitrification, and particularly relates to a core-shell composite material, a preparation method and application thereof, and a treatment method of nitrogen-containing wastewater. The core-shell type composite material provided by the invention is applied to an Anammox process, so that the rapid enrichment of anaerobic ammonia oxidation sludge is realized, and the protection effect on the anaerobic ammonia oxidation sludge is realized by screening adverse factors such as heavy metals and antibiotics in wastewater; under the synergistic effect of the biochar, the transition metal and the molecular sieve, the combined effect of enriching and protecting the AnAOB is realized. The core-shell composite material provided by the invention can promote stable operation of an anaerobic ammonia oxidation process in an actual wastewater treatment process and large-scale engineering application of the process.
