浸没式水处理填料制备技术研究进展

Research Progress on Preparation Technology of Submerged Water Treatment Fillers

综述了污水处理领域曝气生物滤池中常用浸没式填料——新型陶粒填料和改性火山岩填料的制备技术,利用文献比较了不同制备原料在最佳配比及最佳制备条件下得到的多种新型陶粒填料的理化性能指标和生物处理效果,关注了经改性处理的火山岩填料的性能提升以及该领域的研究缺失,指出利用传统填料进行改性处理以及有效利用工业生产废弃物开发新型填料,可以达成制备成本低廉且性能优良的目的,将是浸没式水处理填料领域的未来发展方向。

Preparation technology of two types of immersion packings used in biological aerated filters,including ceramsiteand volcanic rocks,were reviewed in this paper.Physical-chemical properties and biological treatment effect of ceramsitefillers,in the preparation of the best ratio of different raw materials and the best preparation conditions were comparedby literature.The improvement of the performance of modified volcanic rock fillers and the lack of research in this field werealso discussed.It is pointed out that the use of modification treatment by traditional fillers and the new development of packingmaterials with industrial waste could achieve the goal of low cost and good performance.It would be the developmentdirection of the field of immersion water treatment fillers.
