粉煤灰生物填料在污水接触氧化处理中的应用研究

The Research of the Biologic Padding of Fly Ash Applied in the Sewage Transaction

本文讨论了改性粉煤灰加气混凝土作为接触氧化生物填料在污水处理中的应用。叙述了该填料的吸附和接触氧化机理;研究了该填料的用量、曝气时间及曝气方式对污染物去除的影响;并与聚乙烯填料和粉状粉煤灰进行了比较;分析了改性粉煤灰加气混凝土填料在污水中曝气前后晶体结构的变化情况。

This paper discussed apply of modified fly ash vesicant concrete by way of the biologic padding of contact oxidation in sewage transaction. Narrated mechanism of adsorbent and oxidation about this padding ; Researched the influence about this padding dosage on wipe off pollutant, huff time and huff quomodo of packing; Compare capability of wipe off on pollutant with polythene packing and powdery fly ash ; Analysed crystal structure of the contact oxidation biologic padding of fore - and - aft at huff air in the sewage transaction.
