Porous biological filler for purifying polluted seawater as well as preparation method and application of porous biological filler
The invention discloses a porous biological filler for purifying polluted seawater as well as a preparation method and application of the porous biological filler, and belongs to the technical field of sewage treatment. The biological filler is composed of an external porous mineral sphere and an embedded carbon source organism, the mass ratio of the porous mineral sphere to the embedded carbon source organism is 7.5-8.5: 1.5-2.5, the porous mineral sphere has a single channel and a porous skeleton structure, the embedded carbon source organism forms a slow-release organic carbon source, and the slow-release organic carbon source forms a slow-release carbon source. The biological filler contains a plurality of mineral substances, has a large surface area due to intercommunication of gaps, and has the advantages of slow release of a carbon source, facilitation of biological redox and the like. The porous biological filler prepared by the invention has a relatively large specific surface area, a communicated pore structure, multiple mineral components, a slow-release organic carbon source and a substance for promoting electron transfer, is not easy to harden, and can obviously improve the problems of slow growth, difficult aggregation and the like of water treatment microorganisms caused by the conditions of high seawater salinity and the like; the method can be used for removing pollutants in polluted seawater, and especially has an ideal nitrogen removal effect.
本发明公开了一种用于污染海水净化的多孔生物填料及其制备方法与应用，属于污水处理技术领域。该生物填料由外部的多孔矿物球体和内嵌碳源有机体，所述多孔矿物球体和内嵌碳源有机体的质量比为：7.5‑8.5:1.5‑2.5，所述多孔矿物球体具有单通道及多孔骨架结构，所述内嵌碳源有机体形成缓释有机碳源，所述生物填料含有多种矿物质、空隙互相连通表面积大、具有缓释碳源、利于生物氧化还原等优点。本发明制得的多孔生物填料具有较大比表面积、连通孔隙结构、多矿物组分、缓释有机碳源和促进电子传递的物质，不易板结，可显著改善因海水盐度高等条件造成的水处理微生物生长缓慢和聚集困难等问题，可用于去除污染海水中的污染物，尤其对氮的去除效果较为理想。
