城镇污水厂除臭技术应用现状及发展前景概述

摘要

Aiming at present pollution situation of stench in municipal sewage treatment plant, application status and development prospect of deodorization techniques in sewage plant at home and abroad were summarized. A variety of present techniques used in sewage treatment plants' stench were introduced, mainly including biological, chemical, masking method, ion method and adsorption method, and the advantages, disadvantages and application examples of each techniques were listed; several deodorant techniques and assembled techniques with great development prospect for sewage treatment plant were summarized respectively, including biological (Biological Filter, Biological Trickling Filter, and Soil Filter Bed), ion method (High-energy Ion Method, Active Oxidation Method, and the method of Low Temperature Plasma), and Plant Extraction+Biological Filtration, Chemical Washing+Biological Filtration, Plasma+Biological Filtration, etc.%针对城镇污水处理厂臭气污染现状，对目前国内外污水厂除臭技术应用情况和发展前景进行了概述。介绍了现阶段应用于污水厂恶臭污染治理的多种技术，主要包括生物法、化学法、掩蔽法、离子法、吸附法几大类，列举了每项技术的优缺点及应用实例；总结了几类极具发展前景的污水处理厂除臭技术及技术组合，包括生物法(生物滤池、生物滴滤池、土壤过滤床)、离子法(高能离子法、活性氧化法、低温等离子法)和植物提取液+生物过滤、化学洗涤+生物过滤、等离子体+生物过滤等。
