【摘要】 污水处理厂产生大量的成分复杂的污泥，如果不加以妥善处理，将会对环境造成危害。脱水是污泥处理处置中的关键环节。对污水处理厂剩余污泥预处理技术进行了综述，论述了几种化学预处理方法，包括酸/碱预处理、臭氧预处理、Fenton预处理、过硫酸盐预处理、高锰酸盐和高铁酸盐预处理等技术的研究进展，讨论了不同预处理方法对污泥脱水性能的影响。更多还原

【Abstract】 Sewage treatment plants produce a large amount of sludge with complex composition, which will cause harm to the environment if not properly treated.Dewatering is a key step in sludge treatment and disposal.Several chemical pretreatment methods, including acid/alkali pretreatment, ozone pretreatment, Fenton pretreatment, persulfate pretreatment, permanganate pretreatment and ferrate pretreatment, were reviewed in this paper.The influence of different pretreatment methods on sludge dehydrating performance was discussed.更多还原
