摘　　要：阐述了水热、超声、微波、臭氧、化学淋滤、生物沥浸、水解酸化等堆肥预处理方法的概念、原理和特点,分析了不同预处理方法对污泥堆肥特性、污染物的降解和去除以及肥质肥效的影响。基于堆肥的污泥预处理,可去除污泥中部分有毒有害物质、缩短堆肥时间、加快发酵速度、减少氮素损失、提高养分含量,是满足污泥安全土地利用的有效手段。还对组合预处理相较单一预处理的技术优势进行了归纳总结,指出高效、低耗、安全的预处理组合方法将成为城市污泥堆肥及其土地利用研究的重点。The concepts,principles and characteristics of compost pretreatment methods such as hydrothermal,ultrasound,microwave,ozone,chemical leaching,biological leaching,hydrolytic acidification,etc.are described,and the characteristics of sludge composting and the degradation of pollutants by different pretreatment methods are analyzed.Removal and the effect of fertilizer efficiency.Pretreatment of sludge based on composting can remove some toxic and harmful substances in sludge,shorten composting time,speed up fermentation,reduce nitrogen loss,and increase nutrient content.It is an effective means to meet safe land use of sludge.At the same time,the technical advantages of combined pretreatment compared with single pretreatment are summarized,and it is pointed out that efficient,low-consumption,and safe combined pretreatment methods will become the focus of urban sludge composting and land use research.
