摘　　要：选取厦门市8大重点监测行业370家企业的439套废气处理系统进行了调研,对不同VOCs治理技术在不同行业的应用情况及实际净化效果进行分析,并结合GIS平台,对厦门市的VOCs治理效果进行了区域性评估。结果表明:活性炭吸附、UV光解、UV光解+活性炭、等离子+UV光解、燃烧类工艺及其他类(低温等离子法、冷凝回收法、生物法)等6类治理技术对VOCs的平均去除率分别为79.6%、73.7%、71.9%、69.2%、82.1%、68.6%;燃烧类工艺对苯系物去除率最高,其次是活性炭吸附工艺,UV光解及其组合工艺对苯系物的去除率较低;UV光解及其组合工艺在设备管理及企业工艺选取方面尚存在问题,整体处理效果较差,但该工艺适用于低浓度有机废气的处理,例如在汽修行业的去除率较高(80%左右);燃烧类工艺及活性炭吸附工艺处理效果较好,燃烧类工艺的去除率较高,且对工况的适应性较强,可用于高浓度VOCs(>1000 kg·d^(-1))和高进口风量(>20000 m^(3)·h^(-1))条件下的废气治理;其他类相关工艺由于成本较低,虽处理效率不高,但可根据实际情况选择应用。厦门市域各二级行政区对VOCs 8大重点监测行业区域治理效果排序为:思明区>湖里区>海沧区>翔安区>集美区>同安区。370 enterprises(439 waste gas treatment systems)in 8 industries subject to intensive monitoring in Xiamen were selected to investigate the application of VOCs treatment technique in different industries and the actual VOCs removal effect.The effect of VOCs treatment in Xiamen regionally was evaluated based on a GIS platform.Results show that the average removal rates of VOCs by 6 treatment processes,i.e.activated carbon adsorption,UV photolysis,UV photolysis+activated carbon,plasma+UV photolysis,combustion process and other processes(cryogenic plasma,condensation recovery and biological process)were 79.6%,73.7%,71.9%,69.2%,82.1% and 68.6%,respectively.Combustion process has the highest removal rate of Monoaromatic Hydrocarbons(MACHs),followed by adsorption of activated carbon process,and UV photolysis and its associated processes.UV photolysis and its associated processes have problems in equipment management and selection of process and the overall treatment effect is poor.However,the process is suitable for the treatment of low concentration waste gas,e.g.the removal rate is high(about 80%)in the automobile repair industry.Combustion process and activated carbon adsorption process have good treatment effect.Combustion process has high VOCs removal rate and strong adaptability to different working conditions.It can be used for the treatment of high concentration of waste gas under high VOCs production(>1000 kg·d^(-1))and high inlet air volume(>20000 m^(3)·h^(-1)).Although the treatment efficiency of other processes is not high,they can still be used because of its low cost.The regional treatment effect of 8 industry enterprises subject to intensive monitoring of VOCs decreases in the order of Siming District,Huli District,Haicang District,Xiang’an District,Jimei District,and Tong′an District.
