摘要
对目前国内外污水厂除臭技术的现状进行了综述,介绍了目前应用于城市污水厂恶臭污染治理的多种技术,并对其优缺点进行比较。分析结果表明,水洗法和喷淋法简单易行,但对臭气的去除率较低;药剂吸收法和活性炭吸收法可以达到较好的去除效果,但是运行费用较高;而生物除臭法对臭气的去除率高、运行费用低、无二次污染,是一种较为经济有效的除臭技术,也是今后污水厂除臭技术的主要发展方向。
The development of odor-control technology currently used in domestic and overseas was reviewed in this paper, various technique used to control the odor gases generated from municipal wastewater treatment plants were introduced, and the advantages and disadvantages of each present method of removal technology were compared. The compared result indicated that water washing and spewing was easy to do but had low removal rate. The method of chemical absorbing and active carbon can remove most of the odors, but the expense is also very high. Biotechnology was economical and effective. It can keep high removal rate with no secondary contamination and will be extensive applied in the ordor treatment of municipal wastewater treatment plants in future.
