Four trickling biofilter designs were assessed as low-energy alternatives to aerobic activated sludge (AS) for the treatment of personal care product industry wastes. The designs included partially submerged packed-media and sponge reactors with and without active aeration. Partial submergence was used to reduce active aeration needs. Simulated colourant wastes (up to COD=12,480 mg/L, TN=128 mg/L) were treated for 201 days, including wastes with elevated oxidant levels. COD and TN removal efficiencies were always >79% and >30% (even without aeration). However, aerated sponge reactors consistently had the highest removal efficiencies, especially for TN (∼60%), and were most tolerant of elevated oxidants. This study shows sponge biofilters have great potential for treating colourant wastes because they achieve high treatment efficiencies and reduce energy use by >40% relative to AS systems.
四种滴滤生物滤池设计被评估为比需氧活性污泥（AS）更节能的替代方案，用于处理个人护理产品工业废物。这些设计包括部分淹没的填充介质和海绵反应器，以及有和没有主动曝气的设计。部分淹没是为了减少主动曝气的需求。模拟的着色剂废物（高达 COD=12480mg/L，TN=128mg/L）进行了 201 天的处理，包括氧化剂水平升高的废物。COD 和 TN 的去除效率始终>79%和>30%（即使没有曝气）。然而，曝气的海绵反应器始终具有最高的去除效率，尤其是对于 TN（约 60%），并且对氧化剂的升高具有最高的耐受性。这项研究表明，海绵生物滤池具有处理着色剂废物的巨大潜力，因为它们实现了高效率，并且与 AS 系统相比，能源使用减少了>40%。
