摘　　要：综述了粉煤灰、改性粉煤灰、粉煤灰制备无机高分子调理剂在污泥调理中的应用,并对各调理剂的调理机理进行了探讨。最后对粉煤灰类调理剂应用于污泥调理时的优缺点进行了分析。认为粉煤灰类调理剂应与其他调理剂联合使用以减少投加量,对于经粉煤灰类调理剂调理后的污泥,其脱水泥饼的后续处置应以资源化利用为主,根据其性质进行不同方式的资源化利用。The application of fly ash, modified fly ash and fly ash-based inorganic polymer conditioner in sludge conditioning were summarized in this article. And and the mechanism of various conditioners were was discussed. At last, the merit and demerit were analysed analyzed when fly ash-based conditioners were applied to the sludge conditioning. The combined utilization between the fly ash-based conditioners and others was considerable, and so that the dosage can be decreased.The subsequent disposal of the sludge after the conditioning of by fly ash-based conditioners should be based on resource recovery based. And different resource utilization ways should be used according to the properties of the sludge.
