污水处理厂臭气的生物滤床处理

恶臭作为世界七大环境公害之一，对人体健康和生态环境会造成严重危害。在污水的输送和处理过程中，以及对所产生的污泥进行处理的过程中，都会有臭味气体散发。如果不施行有效地控制，则对周围空气环境产生污染，影响污水处理厂的正常运行。这里仅对城市污水处理厂和居民生活小区恶臭处理工艺在国内应用现状及局限性进行了介绍和分析，尤其是选择生物滤床这种优化的土壤处理工艺，它利用土壤基质的过滤、吸附、吸收、物理和化学反应、生物降解等功能净化臭气，同时表面种植的植物亦有一定的净化功能，因此，具有经济、美观、管理方便、运行稳定、处理效果好等优点。

Sewage Treatment Plant Ozone Biological Filter Bed Processing

The odor took world one of seven big environment damages, can cause the serious harm to the human bodyhealth and the ecological environment. In in the sewage transportationand the treating processes, as well as to the sludge which producescarries on processing in the process, all can have the fetid odor gassending out. If does not execute effectively controls, then has thepollution to the surrounding air environment, affects the sewagetreatment plant the normal operation. Here only has carried on theintroduction and the analysis to the city sewage treatment plant andthe inhabitant small - unit residential area odor processing craft inthe domestic application present situation and the limitation, choosesbiological filter bed this kind, of optimization in particular the soilprocessing craft, it filters, function purification ozone and so on the adsorption, absorption, physics and chemical reaction, biodegradation using the soil matrix, simultaneously the superficialplanter plant also has the certain purification function, therefore, has artistic, the management economically convenient, the movementstable, the processing effect is good and so on the merit.
