Microcellular foaming light pyrite material as well as preparation and application methods thereof
The invention discloses a microcellular foaming light pyrite material and a preparation and application method thereof, and belongs to the technical field of environment-friendly materials and sewage treatment. According to the invention, a carbon dioxide foaming technology under the condition of high pressure and even supercritical pressure is used for a foaming process of a modified inorganic material for the first time, CO2 fluid is pumped into a reaction kettle, and then pressure is released to obtain the microcellular foaming light material, and the material has a large number of uniform micron-sized microcellular structures, so that the foaming efficiency is improved. The compressive strength, the porosity and the sewage contact area of the material can be greatly increased, the pH can be autonomously regulated, and more biomass can be attached, so that the stable and rapid nitrogen and phosphorus removal capability is realized.
本发明公开了一种微孔发泡轻质硫铁矿材料及其制备与应用方法，属于环保材料和污水处理技术领域。本发明首次提出采用高压乃至超临界压力条件下的二氧化碳发泡技术用于改性无机材料发泡工艺，将CO2流体泵入反应釜中，而后泄压得到微孔发泡轻质材料，所述材料具备大量均匀的微米级微孔结构，不仅可以大大增加材料的抗压强度、孔隙率、与污水接触面积，还可自主调控pH、附着更多的生物量，以实现稳定快速脱氮除磷能力。
