脉冲生物滤池脱氮途径
脉冲生物滤池中,附着在滤料表面的硝化细菌和反硝化细菌共同作用实现脱氮。废水生物处理中脱氮过程包括氨化反应、硝化反应和反硝化反应。在氨化菌的作用下,有机氮分解转化为氨氮;氨氮通过硝化菌的作用转化为硝酸氮;硝酸氮再通过反硝化菌的作用还原成气态氮,从水中逸出。

脉冲生物滤池运行影响因素

滤料

滤料是生物滤池处理单元的主体,滤料的选用和布置直接影响滤池对污水净化效果;滤料用具备质地轻、化学稳定性好、强度适宜、表面粗糙易挂膜、吸水性适中等特点。早期选用碎石块作为滤池的填料,粒径一般为25100mm,滤料形状不规则,布置深度一般为l~2m。随着对生物滤池滤料的研究,近年来生物陶粒滤料、煤炭渣等新型填料被广泛使用,净化效果提高,部分滤料优质价廉。滤料的填充用保证层次分明、均匀混合。

PH

污水处理中,微生物的生理活动需要适宜的酸碱度,一般最佳的pH范围在6585之间,生物滤池中亚硝化细菌适宜范围为785,硝化菌的适宜pH675。污水中pH值过高或过低会影响微生物的生理活动以及反硝化反应的产物。对滤池进出水pH要进行监测和记录,必要的情况下进行水质调节。
