摘要

采用绿色屋顶工程作为生物填料，在生物滤池中对油烟进行生物降解。结果表明:当生物滤池培养形成生物膜10 d，进水温度约为33℃，停留时间大于25s，相对湿度85%，VOCs浓度1.0 mg·L−1，流速3.35 m3·h−1时，油烟中VOCs的生物降解效率达到90%以上，去除负荷极限0.30 g·(L·h)−1，而生物填料ΔP保持在2960 mmH2O·m−1以下。

Biodegradation of oil fume in biofilter with green roof engineering

Oil fume was biodegraded in biofilter with green roof engineering as biological packing. The results showed that with biofilter culture forming biofilm for 10 days, inlet temperature at about 33 °C, residence time longer than 25s, relative humidity 85 %, VOCs concentration 1.0 mg·L⁻¹, flow rate 3.35 m³·h⁻¹, biodegradation efficiency of VOCs in oil fume reached over 90%, removal loading limit 0.30 g·(L·h)⁻¹ while ΔP of biological packing kept below 2960 mmH2O·m⁻¹.
