城市污水处理厂恶臭气体的生物处理方法

Biological Treatment Methods of Odor in Urban Sewage Treatment Plants

城市污水处理厂城主要的臭气源是进水和污泥处理部分,即进水格栅、曝气沉砂池、生化池、污泥浓缩池以及最终贮泥池等工序。国内外治理臭气所采用的方法主要有吸附法、吸收法、焚烧、化学氧化和催化燃烧等,然而这些传统的物理化学法存在设备复杂、工艺过程繁琐、能耗高、二次污染后再生困难等问题。生物法具有处理效率高、环境友好、能耗低、运行费用低廉等优点,已广泛应用于恶臭污染问题的解决。

Urban sewage treatment plant is the main odor source of the city water and sludge treatment parts, namely the intake grille, aerated grit chamber, biochemical pool, sludge concentration pool and eventually mud pools and other process. Governance at home and abroad to smell the method adopted by the adsorption method, absorption method, burning, such as chemical oxidation,catalytic combustion, however,the traditional physical chemi cal method exist complicated equipment,process trival,high energy consumption,secondary pollution after regenera tion difficulty. Biological method has high processing efficiency ,environmental friendly,low energy consumption,op eration cost is low wait for an advantage,has been widely applied in the stench pollution problem.
