随着中国经济和城镇化的迅速发展,城市污水处理量大幅增加,污水处理厂产生的污泥也随之增长.由于污水厂污泥产量增长迅速、成分复杂等特点,若处理不当,不仅会对环境造成二次污染,同时也是对污泥中所含营养资源的一种浪费.不同的国家根据本国的国情对污泥处置的方法各有不同的特点和侧重.本文对各国污水处理厂污泥处理的现状进行了比较和分析.同时对世界各国污泥处理的研究及最新进展工作进行了梳理和介绍,特别着重介绍了厌氧消化技术与其他技术结合处置城市污泥研究进展和技术创新.同时结合国内实际,指出了污泥处理的发展趋向.

With the rapid development of China's economy and urbanization,the waste sludge discharged from city sewage treatment plant also has a rapid output growth. Because of the complex composition of the sludge,if treated improperly,it can cause not only second pollution to the environment,but also a waste of resources of nutrient components in the sludge. Different countries,according to their local conditions for sludge disposal,have different treatment methods with their own characteristics. In this paper,the present situation of sludge treatment is analyzed and different treatment methods are com-pared. At the same time the global wide study of sludge treatment process and the latest progress were reviewed and intro-duced,with a special attention being given to the combination of anaerobic digestion and other technology to the treatment and disposal of sludge. Taking into consideration the actual situation of sludge treatment in China,the authors pointed out the technological development trend of sludge treatment.
