污水处理厂污泥处理与处置探索 总被引:4,自引:1,他引:4
嘉兴联合污水处理厂引进德国Passavant Roediger污泥脱水系统,脱水后的污泥含固率达45%。脱水污泥经干化后,运至邻近水泥厂作为水泥生产的原料而被综合利用。该厂污泥处理与处置的方法真正实现了污染物的零排放,具有经济可行性。 相似文献

Sludge production and disposal are entering a period of dramatic change, driven mainly by EC legislation. The urban waste water treatment Directive will result in at least 50% more sludge being produced by the end of 2005 and, during the next decade, sludge disposal to all the established outlets could become increasingly difficult or, in the case of sea disposal, will become illegal. The challenge facing the members of the European Union is how to (a) maintain cost-effective and secure methods of sludge disposal and (b) engender public confidence in all disposal and recycling options. What is required is not so much innovative technology, although this may be essential, but more innovative attitudes and approaches to promotion and defending existing outlets.
This paper describes the likely pattern of sludge production, treatment and disposal which will emerge during the implementation of recent EC directives and other national policies in Europe, and focuses on the areas and issues which require innovative approaches. 相似文献

This paper reviews the sludge treatment and disposal operation in The Netherlands where the total volume of sludge is increasing and the sales potential is falling due to stringent quality requirements. The sludge can no longer be recycled to agriculture and has to be dumped on land. The techniques available for this purpose make sludge disposal much more expensive.
A meticulous analysis of the entire sludge chain seems to be necessary to control the costs and minimize the environmental impact, and a start has recently been made on the formulation of ideas in this context. 相似文献

Current Technologies for Sludge Treatment and Disposal 总被引:3,自引:0,他引:3
This paper reviews the current sludge technologies and discusses likely future trends associated with those technologies. It describes the role of thickening, dewatering, pasteurization, stabilization, thermal destruction and product enhancement to satisfy environmental standards. Reference is made to technologies which, for decades, have been associated with sewage sludge but where market conditions have forced R and D initiatives to be introduced and commercialized. 相似文献

The paper attempts to review current and future practices in the UK against a European background.
Sludge disposal has become a subject which is developing rapidly again and, since the presentation of this paper, there have been a number of developments, e.g. the adoption by the EC of its hazardous waste Directive in December 1991. Untreated sludge or sludge which is unsuitable for use in agriculture will be classified as a hazardous waste, subject to certain criteria. This makes the work on sludge classification even more crucial. 相似文献

污水污泥处理的碳排放及其低碳化策略 总被引:3,自引:0,他引:3
污水污泥处理过程中的碳排放是温室气体的重要来源.为了促进污泥处理过程的碳减排,针对常用污泥处理技术采用质量平衡模型进行碳排放核算,通过低碳化程度评估,建立了面向不同层次需求的污水污泥低碳化处理策略.结果表明,污泥厌氧消化产沼利用、余热干化后焚烧或混烧发电等技术的低碳化程度最高,分别为89.6%、80.3%和76.6%;... 相似文献
