污水处理厂恶臭污染物处理方法概述

城镇污水厂排放出的H2S，CH4，NH3，以及胺类、硫醇、有机硫化物等臭气对人类身体健康造成很大危害，也对空气质量带来很大压力。根据去除恶臭气体的原理对物理法、化学法、生物法进行了介绍，分析了各种除臭方法的适用条件及缺点。研究表明，利用单一方法除臭效率有限，难以满足除臭要求，因此需采用两种以上方法进行联合处理，以提高除臭效率。;Odors such as H2S,CH4,NH3,amines,mercaptans,and organic sulfides emitted from municipal wastewater plants pose great harm to human health and put great pressure on ambient air quality.Physical,chemical,and biological methods are introduced based on the principle of removing malodorous gases.The applicable conditions and shortcomings of various deodorization methods are analyzed.Deodorization efficiency is limited by a single method,and it is difficult to meet the deodorization requirement.Therefore,it is necessary to consider two or more methods to jointly improve the deodorization efficiency
