- 摘要:
- 传统滤料在处理复杂水质原水时存在效率低和维护成本高等局限性，亟待开发新型滤料以提高净水效率和降低运营成本。基于此，探讨了一种以煤焦渣和活化沸石为主要成分的新型滤料的过滤吸附及絮凝沉降性能，并以辽宁某乡镇地表水净水厂沉淀池出水为研究对象，通过新型滤料与传统石英砂滤料的过滤对比实验，评估该新型滤料的过滤效能及过滤周期等关键运行参数。新型滤料经高温烧结而成，主要成分为硅、铁、铝、碳，在8.15~12.80 m/h高滤速条件下，其过滤水量较传统石英砂滤料提升约16%~60%，且出水浊度低于0.5 NTU，出水Al3+浓度为0.16~0.19 mg/L，均优于传统石英砂滤料。因此，新型滤料具有替代传统石英砂滤料的潜力，能够提高过滤水量及工艺运行效果。
- Abstract:
- Traditional packing media exhibit limitations in treating complex water quality raw water, including low filtration efficiency and high maintenance expenses. Therefore, there is a pressing need to develop new packing media to enhance water purification performance and reduce operational costs. The performance of a new packing medium—primarily composed of coal coke slag and activated zeolite—in terms of filtration, adsorption, and flocculation sedimentation for drinking water purification was systematically evaluated. Using the effluent from the sedimentation tank of a surface water purification plant in a town in Liaoning Province as the source water, a comparative filtration experiment was conducted between the new packing media and conventional quartz sand to assess key operational parameters, including filtration efficiency and filtration cycle. The new packing media were sintered at high temperature and its primary components were silicon, iron, aluminum, and carbon. Under filtration velocities ranging from 8.15 m/h to 12.80 m/h, the filtration capacity of the new packing media increased by approximately 16% to 60% compared to conventional quartz sand. Furthermore, the effluent turbidity was lower than 0.5 NTU, with Al3+ concentration of 0.16~0.19 mg/L, both parameters demonstrating superior performance relative to traditional quartz sand. Therefore, the new packing media has the potential to replace traditional quartz sand, as it can enhance both the filtration capacity and the overall process performance.
