人工强化生态滤床技术在条子河水体改善工程中的应用

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。

Applied Research on Artificial Strengthen Ecological Filter Bed Tecnology for the Improvement of the Water in TIAO ZI River Project

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 greater 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.
