摘要
对近几年国内外污水处理厂(WWTPs)污泥中磷回收技术的研究进行了总结,概述了人为活动引起的磷的循环过程,详述了污泥中磷回收过程中污泥的预处理、磷的回收方法和工艺技术。在此基础上,对该领域的研究前景进行了展望,总结了各种技术的优缺点,提出应进一步对污泥水解释磷的最佳条件以及有机磷的回收进行探索研究。
The recent researches on phosphorus recovery from sewage sludge in WWTPs have been reviewed in this literature review,and the cycle of phosphorus due to the human activities has been summarized.According to the latest research,the technology of phosphorus recovery and the pre-process of sludge have been analyzed in the meantime.Moreover,the advantages and disadvantages of various technologies have been discussed in the end.It put forward that the future research should focus on the optimum condition for phosphorus release from sludge and the recovery of the organic phosphorus.
