摘要
惡臭污染物是僅次于顆粒污染物的又一大類(lèi)氣態(tài)污染物。對(duì)于低濃度惡臭污染的控制較難。尋求合理的治理途徑和控制方案已成為世界各國(guó)亟待解決的熱點(diǎn)課題。生物法凈化惡臭氣體是近年來(lái)發(fā)展起來(lái)的工藝，與傳統(tǒng)凈化工藝相比，具有設(shè)備簡(jiǎn)單、投資少、運(yùn)行費(fèi)用低、無(wú)二次污染等優(yōu)點(diǎn)，因而受到學(xué)者的重視。

Abstract
Odor pollutant particles of pollutants is the second largest category of another gaseous pollutants. To control low-concentration smog pollution is difficult. For rational management and control programs have become the world's countries need to resolve the hot topic. Biological purification odors in recent years to develop the technology with the traditional purification process when compared with simple equipment, small investment, low operating costs and no secondary pollution advantages, thus academics seriously.
The graduation design direction is the use of biological treatment of low concentration of odorous gases design, taking into account the economic feasibility of engineering graduates of the design decisions biological trickling filter technology. Lin designed to hardwood timber sawdust as filler, by gas humidification and adjust pH, so that the stench of gas components of the microbial decomposition of the effects of carbon dioxide and water. Specific content of the gas flow is determined by the design of low biological filter, and other equipment to clean up the malodorous gases including gas gathering enclosures. piping layout, fan choice, the blower, fillers and other aspects of the design, to achieve 90% eliminate the stench of the ultimate effect of pollutants.
Keywords : Odor，Biological，Biotrickling filter
