污泥消毒技术的应用及进展

Application and Progress of Sludge Disinfection Technologies

污泥是污水处理过程中产生的固体物质,不仅含有大量的有机质和N、P、K等营养元素,同时还含有大量细菌、病毒及寄生虫,需进行消毒处理后才能处置,但其消毒副产物会引起生态环境的负面效应。安全、可靠的消毒技术成为近年来污泥处理研究的热点。介绍了目前污泥消毒技术的应用及进展,并指出了今后的发展方向。

Sludge is the solid materials produced in wastewater treatment, which contains a lot of organic matter and plant nutrition matters （nitrogen, phosphorus and potassium） as well as a great deal of bacteria, virus and parasite. Therefore, sludge must be disinfected before disposal. However, the byproducts from sludge disinfection will result in negative ecological effect. So the research in sludge treatment focuses on safe and effective disinfection technologies for these years. The application and progress of sludge disinfection technologies were introduced, and the perspective of the technological development in the future was pointed out.
