Biological filter ball capable of synchronously purifying polluted water body and bottom mud, application of biological filter ball and farmland drainage ditch purification system
The invention belongs to the technical field of sewage treatment, and particularly relates to a biological filter ball capable of synchronously purifying polluted water and bottom mud, application of the biological filter ball and a farmland drainage ditch purification system. The invention provides a biological filter ball capable of synchronously purifying polluted water and bottom mud. The biological filter ball comprises a porous spherical filter screen (5) and a filter filler filled in the porous spherical filter screen (5), the filter filler comprises a biomass filler core (1), and an iron-carbon filler layer (2), a zeolite layer (3) and a ceramsite layer (4) which sequentially wrap the outer surface of the biomass filler core. The filler structure in the filter ball is accurately arranged, so that the obtained biological filter ball can effectively remove ammoniacal nitrogen, nitrate nitrogen, total phosphorus and organic pollutants in farmland drainage at the same time; in addition, in the using process, the biological filter ball is easy to update and maintain, and the long-term effective effect of the biological filter ball is achieved.
本发明属于污水处理技术领域，具体涉及一种可同步净化污染水体和底泥的生物滤球及其应用、农田排水沟净化系统。本发明提供了一种可同步净化污染水体和底泥的生物滤球，包括多孔球形滤网(5)和填充在所述多孔球形滤网(5)中的过滤填料；所述过滤填料包括生物质填料芯(1)和依次包裹在所述生物质填料芯外表面的铁碳填料层(2)、沸石层(3)和陶粒层(4)。本发明通过精确设置过滤球中的填料结构，使得到的生物滤球能够同时有效的去除农田排水中的氨态氮、硝态氮、总磷和有机污染物；且在使用过程中，生物滤球易于更新维护，实现了生物滤球的长期有效作用。
