污泥焚烧工艺技术研究

THE STUDY ON THE WASTEWATER SLUDGE INCINERATION TECHNOLOGY

目前焚烧工艺被世界各国认为是污泥处理中的最佳实用技术之一。在欧洲、美国、日本等国家,该工艺已日渐成熟,它以处理速度快,减量化程度高,能源再利用等突出特点而著称。并且由于近年来,世界各国的环境条件均对废弃物处理所花费的时间和所占的空间提出了更为严格的要求,因而污泥焚烧技术已逐步成为污泥处理的主流技术。我国在废物焚烧的研究方面起步较晚,特别是在污水厂剩余污泥焚烧这一领域更是缺乏基础性的研究,因此对污泥处理中焚烧这一技术的研究就显得日益重要。

At present the incineration technology is thought as one of the most practicable technology in the field of sewage sludge treatment in the world.In most of countries, such as European countries,America,Japan,etc.,this technology has been very popular and operated successfully step by step.Its obvious advantages are fast disposal speed,decreasing components efficiently and recycle energy as well.And in the recent years most of countries make much more strict regulations on the time and space of disposing wastes, so incineration technology has been a main method of sewage sludge treatment.In China, the study on wastes incineration lags behind the developed countries, especially lacking of fundamental research on the field of sewage sludge incineration.Therefore, the technology of incineration becomes increasingly necessary.
