| 中文摘要 |
| 生物法净化废气通常可分为生物洗涤、生物过滤及生物滴滤等几种形式。不同组成及浓度的废气有其各自合适的生物净化方式。与传统的吸收、吸附及焚烧法相比,生物法净化废气具有费用低,无二次污染等特点。早期的生物废气净化技术主要用于脱臭,近来开始应用于化工等行业排放的挥发性有机废气的净化。在德国、荷兰及日本等国已有近千套生物净化装置投入运行。 |
| 英文摘要 |
| Three biological processes to treat waste gases are the bioscrubber, the bio filter and the biotrickling. Selecting the best biological processes suited for one paticular application depends on the contaminant concentration,stream comPOSition etc. The biological treatment of gaseous emissions offers an inexpensive and environmentally safe alternative to conventional air treatment technologies such as absorption, adsorption and incineration. At first,the biological treatment of gaseous emissions are used to dedorize, and more recently,to remove volatile organic compounds from waste gases emited from chemical processe of industries.In Germany, Netherlands and Japan, there are nearly 1000 biological gaseous treatment systems in service. |
