Self-active nitrogen and phosphorus removal carrier material as well as preparation method and application thereof

The invention relates to a self-active nitrogen and phosphorus removal carrier material as well as a preparation method and application thereof. The self-active nitrogen and phosphorus removal carrier material comprises a sulfur-containing carrier, and a weakly alkaline mineral material, an iron-based material and a microbial growth promoter which are dispersed and filled in the sulfur-containing carrier, the sulfur-containing carrier is a porous carrier material loaded with sulfur. The self-active nitrogen and phosphorus removal carrier material is large in specific surface area and high in uniformity, so that the self-active nitrogen and phosphorus removal carrier material is high in nitrogen removal efficiency and stable in nitrogen removal effect, and the self-active nitrogen and phosphorus removal carrier material is good in sewage treatment effect. 本发明涉及一种自活性脱氮除磷载体材料及其制备方法与应用。该自活性脱氮除磷载体材料包括含硫载体及分散填充于含硫载体的弱碱性矿物材料、铁基材料及微生物生长促进剂；含硫载体为负载有硫磺的多孔载体材料。该自活性脱氮除磷载体材料的比表面积较大且均一性高，因而自活性脱氮除磷载体材料的脱氮效率较高且脱氮效果稳定，该自活性脱氮除
