摘　　要：通过小试装置,考察了温度、曝气位置、曝气强度等因素对人工生态滤床运行效果的影响。结果表明,温度对滤床运行影响较大。但在低温情况下,滤床亦有一定的处理效果。在滤床沿程不同单元进行人工强化曝气,滤床前端处理效果明显优于滤床中后端。低温情况下强化曝气,滤床处理效率也可提高10%以上。这表明人工强化生态滤床技术在河流水体改善应用中处理效果明显,具有可行性和实用性。Artificial strengthen ecological filter bed is a new water purification tecnology which is in accordance with bio-chemicalbed and artificial wetlands principle. Through a small pilot plant, we investigated the influence these factors had on artificial ecological effect of filter bed from the temperature, aeration position, aeration intensity perspectives. The results showed that ： the temperature of the filter bed runs a grea- ter impact. However, at low temperatures, the filter bed has certain treatment effects. In different locations in the artificial filter bed enhanced aeration, filter bed in front is better than the back-end processing filter bed. Even at low temperatures, by strengthening the aeration, filter bed treatment efficiency can be increased by 10% or more. This indicates that the technology of artificial strengthen ecological filter bed is feasible and practical in river water quality improvement applications.
