摘要:
砂滤池过滤是目前水处理工艺中常用的技术手段，其中滤料作为关键材料需要定期检测以符合水处理标准。以天津市某净水厂砂滤池旧滤料为研究对象，与不同有效粒径的新滤料进行掺混，通过过滤试验对比旧滤料、标准粒径滤料、掺混滤料的过滤效果及运行参数，通过筛分试验探讨滤料掺混更新的可能性并进行生产性应用。结果表明，新、旧滤料以相同比例混合后对出水浊度、耗氧量等指标有较好的去除效果，对比旧滤料运行情况，其出水浊度更稳定。实际生产中将旧滤料与有效粒径为0.75~0.85 mm的细滤料进行掺混，当掺混比为15%~20%时，能够满足水处理滤料有效粒径标准，可有效恢复水厂老旧滤池的过滤性能，相比整体更换滤料能明显降低成本。
Abstract:
Sand filter filtration is a widely adopted technology in current water treatment processes, wherein the filter media, as a critical component, requires regular testing to ensure compliance with the water treatment standards. The old filter media from the sand filter in a water purification plant in Tianjin was blended with new filter media featuring different effective particle sizes. Through filtration experiments, the filtering performance and operational parameters of the old filter media, standard filter media, and mixed filter media were systematically compared. Additionally, the feasibility of mixing for upgrading the filter media was evaluated via screening tests, followed by practical application in production. After the new and old filter media were mixed in equal proportions, the effluent demonstrated improved performance in terms of turbidity and oxygen consumption removal. Additionally, the effluent turbidity remained more stable compared to the operation using only the old filter media. In full-scale application, blending the old filter media with fine filter media having the effective particle size of 0.75-0.85 mm could meet the effective particle size standard for water treatment filter media when the mixing ratio was maintained at 15%-20%. This approach effectively restores the filtration performance of the existing filters in water treatment plants while significantly reducing production costs compared to complete replacement of the filter media.
