摘　　要：在某鱼粉厂建立了三甲胺（TMA）、臭气生物过滤床工程装置.该系统采用了棕纤维复合生物填料，在温度为25-35℃、空床停留时间（EBRT）20.0s、TMA进气浓度为536-895mg/m^3、臭气浓度为9724-13431倍时，系统对TMA、臭气的平均去除率分别达91.98%、98.70%.EBRT和进气浓度对净化效率影响明显，进气TMA浓度1500-1600mg/m^3时，EBRT从22.5s增加至60.0s，TMA去除率从64.67%提高到84.38%.同时，系统对TMA降解中间产物NH3也表现出良好的去除效果.A full-scale biofilter was installed at a fish-meal manufacturing factory to degrade high concentration trimethylamine contaminated waste gas. Palm fibre combined media was packed in the biofilter. The average removal efficiency of TMA, odor was 91.98% and 98.70% at the temperature of 25-35℃, the empty bed residence time （EBRT） of 20.0s for the TMA inlet concentration of 536-895 mg/m^3 and the odor inlet concentration of 9724-13431 times. The influences of EBRT and inlet concentration on the removal efficiency of trimethylamine were investigated and discussed. When trimethylamine concentration was 1500-1600 mg/m^3, EBRT increased from 22.5s to 60.0s, trimethylamine removal efficiency enhanced from 64.67% to 84.38%. Additionally, the intermediate NH3 was also removed in this system during trimethylamine degradation.
