摘要
污泥是城市污水处理厂的伴生产物,也是一类可利用性极高的二次资源,对污泥资源化技术的研究一直备受国内外学术界的关注。本文讨论了国内外污泥处理的现状,并对目前各种污泥处理方法进行了比较。在此基础上提出污泥资源化的一些途径,认为污泥资源化将是我国污泥处理的主要发展方向。同时指出,污泥资源化在中国的发展不仅需要在技术上持续创新,更重要的是在政策上大力支持。
As a concomitant of sewage treatment in urban effluent reatment plant,the sludge was also a kind of reuseful resource.More and more attention had been paid to the researched on sludge resource utilization technologies since the problem was brought out.The disposal actualities of the sludge in China and other countries were analyzed,and many disposal techniques at present were also compared.Based on these facts,some comprehensive utilization methods of the municipal sludge were put forward.It was considered that the comprehensive utilization should be the main development direction for the municipal sludge disposal in China.It was also pointed out that the persistent innovations of the technologies and support from government would act as the impetus for the sludge utilization in China.
