Unfired autotrophic denitrification nitrogen and phosphorus removal filter material as well as preparation method and application thereof
The raw materials of the filter material comprise sulfur, pyrite and siderite, the mass ratio of the sulfur to the pyrite to the siderite is (5-7): (2-4): 1, and the particle size of the sulfur, the particle size of the pyrite and the particle size of the siderite are all 100-200 meshes. The invention also provides a preparation method and application of the unfired autotrophic denitrification nitrogen and phosphorus removal filter material. According to the method, the preparation process of the filter material is simplified, a high-temperature firing process is not needed, and the prepared unfired autotrophic denitrification nitrogen and phosphorus removal filter material has the advantages of being low in preparation cost, small in investment and easy to implement; the preparation process is simple and low in technical difficulty; the production cost is low, and the benefit is good.
本发明公开了一种该滤料的原料包括硫磺、硫铁矿及菱铁矿，所述硫磺、硫铁矿及菱铁矿的质量比为5‑7：2‑4：1，所述硫磺、硫铁矿及菱铁矿的粒径均为100‑200目。本发明还提供了一种免烧自养反硝化脱氮除磷滤料的制备方法和应用。本发明方法的制备过程简化了滤料制作工序，无需高温烧制过程，制备得到的免烧自养反硝化脱氮除磷滤料具有制作成本低、投资小，易于实施；制备工艺简单，技术难度小；生产成本低，效益好等优点。
